Before, it took 30 minutes. What changed? My mPulse sauna **Developer response:** Thank you for bringing this to our attention. We're sorry to hear this has been your experience. We'd love the opportunity to better understand what's happening with your sauna. If you haven't already, please connect with our Customer Care team. They would be happy to review your setup and troubleshoot so you can get back to enjoying your sessions. Feel free to reach out at 877-292-0020 x3 or through our website: https://www.sunlighten.com/customer-service/#support-form ### 3/5 — Better Wireless Functionality *2026-03-08* The tablet within the sauna is slow and not always touch responsive. I would love it if the app was able to be able to connect to the sauna from anywhere (not specifically the same network). Also, with multiple users in the house, if the tablet isn’t logged into my profile after another user uses the sauna, the scheduled program won’t run. That seems like an oversight. **Developer response:** Thank you for sharing this with us. We’re sorry to hear this has been your experience. Our team is here to help ensure you’re getting the most from your sauna and app experience. If you haven’t already, we’d love to connect and share tips for using the tablet to help make things as easy as possible.

It turned the sauna on. It reported the correct temp. It didn’t push random popup windows. Now that has changed. The app is not reliable for the basics - turning on the sauna and reporting a correct temperature. And the developer added 2 new popup windows to bombard users and attempt to force them to share location and Bluetooth. Neither of these is necessary for the app to communicate with the sauna. But as expected, Sunlighten has jumped onboard the data collection train and made the customer into the product. We don’t appreciate the daily intrusion demanding that we share our location and connect via Bluetooth. Declining these options ONE TIME should be respected by the company. As they say, NO MEANS NO. We are daily sauna users but even our dedication to this company isn’t enough. They aren’t listening to the feedback. I will gladly update my review if they alter the app to respect the privacy and decisions made by customers. But if they can’t do that then we will definitely choose a different brand next time. **Developer response:** Thank you for taking the time to share your experience. We’re sorry to hear about your frustrations and want to assure you that we take customer feedback seriously. Our team has been making improvements to enhance app stability and connectivity, and we’d love the opportunity to assist in troubleshooting your specific issues. Please reach out to our Customer Care team at 877-292-0020x3 so we can work toward a solution. Your feedback is invaluable in helping us continue to improve, and we truly appreciate it. ### 3/5 — Remote Start app *2026-03-02, version 3.3.0* Finally! I can start the sauna up while I am coming back from gym! ### 2/5 — Mehhh *2026-01-29* This app is very limited. I cant turn my sauna on from wherever im at you have to be soo close. Mine is at my place of business, crazy how much we pay for the sauna's (which I do love) to not be able to turn it on without being soo many feet from it. I have a smart strip outlet that I can literally turn my things on and off from anywhere but I can't do the same with my sauna. Also it send notifications on the phone of when sauna is started when preheat is done and what program is starting and when program is done, but I can't go into the app and look at these notifications which is weird to me. The app needs more work to it in my opinion but I'm just one person I guess just a few things to take into consideration. **Developer response:** Thank you for taking the time to share this feedback. We’re sorry to hear about your experience and appreciate you being open about what would make the app more useful for your routine. Since your review was written, we’ve released an update that expands remote access range, making it possible to start your Sunlighten sauna from much further away. This was designed to add more flexibility, whether your sauna is at home or at a place of work, so you can have it ready when you are. We hope you enjoy the new updates, and please don’t hesitate to reach out if we can help with anything. Thank you again for choosing Sunlighten. We look forward to continuing to support you for years to come. ### 3/5 — Almost Perfect: Great Sauna, Frustrating App Limitations *2026-01-28* I love having my Sunlighten sauna at home. It feels like a luxury experience and the convenience of not having to go to the gym makes it much easier to use consistently and enjoy the benefits. The built-in tablet is easy to use and a great feature. I can log into preloaded apps to watch shows, connect to Bluetooth for music, or take phone calls, which really enhances the experience. My biggest frustration is the Wi-Fi and app functionality. I agree with other reviewers who are frustrated by the inability to connect to or start the sauna when not at home. At this price, remote start feels like a reasonable expectation, especially since many other home devices (like tvs, fridge, stove, washing machine, robot vac, etc) allow true remote access, so the technology is out there. This should have been disclosed at the time of purchase. I also notice occasional subtle creaking sounds when sitting inside. It looks solid overall, but the noise slightly detracts from the premium feel. Overall, I truly love my Sunlighten sauna and the convenience of having it at home. Adding true remote start capability and addressing minor build noises would make it an even better experience. **Developer response:** Thank you for taking the time to share such thoughtful and detailed feedback. We’re truly glad to hear how much you’re enjoying your Sunlighten sauna and that it has become a meaningful part of your home wellness routine. Since your review, we’ve released updates that expand remote access range, designed to make it easier to start your sauna from further away and add more flexibility to your routine. We understand how important this convenience is, and feedback like yours continues to help guide our improvements. We'd love for you to try it out and don't hesitate to reach out if you need assistance with the update. While some minor natural wood movement can occur with use and temperature changes, we understand how this can impact the premium feel, and we’ll be sure to share your feedback with our team. Thank you again for being part of the Sunlighten community and for helping us continue to improve your experience. ### 3/5 — Fix your Bluetooth it’s unreliable *2025-12-27, version 3.2.0* It’s an OK attempt at a first app. But the Bluetooth connection is wonky and unreliable with Spotify. Not a very professional app, given the awesome capabilities of the sauna. ### 2/5 — What is the point? *2025-12-23* Why make an app that only works on the house WiFi? My sauna takes almost an hour to heat up so unless I know exactly when I want to get in or have loads of time when I’m home, I can’t preheat the sauna and use it as much as I’d like. I don’t understand why you would make a $6000 sauna without that capability. I mean for goodness sake I can start my range remotely. I can open my garage remotely, I can turn my landscape lights off and on remotely. This is technology that has been around since WiFi . Sunlighten can’t make an app that allows me to turn on my sauna when I’m at the gym so it’s nice and hot when I get home? No I have to wait until I get home or ask my wife to turn it on. It’s funny I just assumed a WiFi connected sauna would have this capability. Had I known this was just a glorified control panel and that I have to be in my house to turn on my sauna I would have bought a different brand. Come on sunlighten, really?? **Developer response:** Thank you for taking the time to share your feedback. We greatly appreciate your patience as our team worked to release just what you were looking for! Since your review, we’ve released updates that expand remote connectivity and improve how you can control your Sunlighten sauna, including greater flexibility to start your sauna from further away than before. We’d love for you to give it a try and hope it enhances your experience by having your sauna ready when you are. We truly appreciate you sharing how important this functionality is to your routine. Feedback like yours helps guide ongoing improvements, and we’ll be sure to share it with our product team. If you need any assistance getting set up or updated, our Customer Care team is happy to help at 877-292-0020 x3 or via our support form here: https://www.sunlighten.com/customer-service/#support-form ### 3/5 — App needs improvement *2025-11-11* It is nice that I can turn on the sauna and preheat from my phone, but don’t like that preheat time is basically time added to the end of the program. Red light turns off after a while during pre-heat and if you don’t get in right away you don’t get the benefit of the red light. **Developer response:** Thank you for sharing this feedback. We’d love to connect and help provide tips on getting the most out of your Sunlighten sauna experience. Many customers also find it helpful to step into the sauna while it’s preheating when possible, as there are many benefits even at lower temperatures with infrared heat. Our team is happy to walk through best-use tips tailored to your setup if that would be helpful. Feel free to reach out at 877-292-0020x3 or via our web form: https://www.sunlighten.com/customer-service/#support-form We appreciate you being part of the Sunlighten community and are here whenever you need support. ### 2/5 — Current client *2025-10-31, version 3.2.0* Tried to create an account and app never progressed past provision. Bad first time experience ### 4/5 — App is getting better all the time *2025-10-10* When I first got the sauna 2 yrs ago the app was a terrible frustration. The reliability now is much better and gets better with each update. My only ask is for me to be able to start the sauna remotely before I reach the house. Thanks for continuing the improvements. **Developer response:** Thank you for taking the time to share this and for being part of the Sunlighten community. We’re so glad to hear the reliability has improved for you over time, and we really appreciate your patience as we continue making updates. We’re especially excited to share that we’ve recently released updates that expand remote connectivity, giving you more flexibility to start your sauna from further away so it’s ready when you arrive home. We'd love for you to try it out when you're able! Thank you again for your continued support and thoughtful feedback. It truly helps guide ongoing improvements, and we’re grateful to have you on this journey with us. ### 2/5 — One day *2025-10-07, version 3.2.0* We have had the sauna one day and the software is not functioning. It goes in a loop to the login and never turns on. ### 2/5 — Glitchy and inconsistent *2025-07-29* This app has no excuse to be so inconsistent. Sometimes a scheduled sauna goes, too many times it won’t. I don’t understand how the sauna can be so expensive and useful and simultaneously have the worst tech imaginable. Please fix this. **Developer response:** Thanks for your feedback, and we're really sorry to hear about your experience. We'd love the opportunity to help troubleshoot and get things working smoothly for you. Please reach out to our team at 877-292-0020x3 so we can support you directly. Thank you for giving us the opportunity to make your experience better—we’re here to help you get the most out of your sauna. ### 4/5 — Mostly Great *2025-07-12* I do love being able to turn on the sauna from my phone and also being able to create and modify custom programs on the app. I agree with the ones who are saying it would be nice to operate the lights from the app instead of having to use the remote control. BUT it would be so much nicer if it could be operated when I am not already in the house on the same WiFi. Hoping soon this will happen. **Developer response:** Thank you so much for your review and for sharing what you’re loving about the app experience! We’re so glad the remote start and customizable programs are enhancing your sauna routine. We also appreciate your feedback about app connectivity and light control! Our team is always working on ways to evolve and improve, and comments like yours help guide future updates. Thanks again for being part of the Sunlighten community, we’re grateful for you! ### 2/5 — Latest update still deficient *2025-06-02, version 3.2.0* Latest update has certainly improved things but there are still too many gremlins that haven’t been ironed out due to insufficient testing. Recurring appointments always default to year ahead regardless of your end date! Sauna randomly losses connection w wifi even right next to sauna making APP scheduling impossible at those times. Overall time delay lag when scheduling on sauna tablet way too slow. APP is faster so that good…🫤 ## Most critical reviews (10 lowest-rated) ### 1/5 — NOT RELIABLE *2026-02-13, version 3.3.0* Just updated. Now it’s not connecting…AGAIN!!!🧐 ### 1/5 — Doesn’t Work *2026-01-23, version 3.2.0* Would not buy the sauna if I k ew how bad the app and tablet software is. Doesn’t pair and doesn’t work without pairing. Don’t buy it ### 1/5 — Useless *2025-11-11, version 3.2.0* The app can control the audio of the sauna only. Can not actually turn on the amplify sauna. Why would anyone want an app to turn on the audio only 🤣 ### 1/5 — App issues again *2025-10-31* App will not connect to sauna - was told it was a server issue but they refused to disclose if it was an attack or breach or an issue with them and they would not state when the app would be back up - no timeline no information provided, no email or communication to customers. **Developer response:** Thank you for taking the time to share your experience, the interior lighting on the iPhone app was confirmed and has since been addressed. Please update your in-sauna tablet to version 4.1.0. After that, close and reopen the mobile app, and the interior lighting option should return under lighting preferences. We’re sincerely sorry for the delay in communication and appreciate your persistence in following up. Your feedback is a strong reminder of how important both functionality and follow-through are, and we’re actively working to improve on both fronts. If you need any support with the update or have additional concerns, our Customer Care team would love to help. ### 1/5 — Sadly doesn’t turn on sauna remotely *2025-10-31* The sauna tablet sleeps and is never connected to the WiFi when you need the app to tune it n remotely. You literally have to go to the sauna and turn it on for the app to work, making remote app start pointless :( I do LOVE my sunlighten sauna though. **Developer response:** Thank you for taking the time to share this with us, and we’re sorry for the frustration this has caused. We really appreciate you also sharing that you love your Sunlighten sauna. Since your review, we’ve released updates that expand remote connectivity and improve overall control of your sauna, including greater flexibility to start it from further away than before.

Continuously loading ### 1/5 — Company creeps on personal data *2025-05-22, version 3.2.0* Besides, some of the worst code I have ever experienced, all usage data is kept by the company. Really no need for it to creep on his customers. Also, the software is so poorly written that only one person can program the sauna to start remotely. The rep told me that it was something like a Netflix account… I really don’t see the correlation since I already paid for the sauna and Sunlighten will not get additional money from other people using it. Hopefully you are reading these reviews before purchasing a sauna… My advice purchase another brand. ### 1/5 — App issues *2025-05-16* Interior lighting still not available on iphone app - slow response from software engineers who cant seem ti he bothered to fix an issue that was just confirmed to impact multiple iphone users because they are too busy working on new features to stop and fix an issue they caused from a tablet updated. These updates should be tested before being deployed and when an issue comes up for something that worked previously but no longer works - it needs to he fixed ASAP. No one provides updates from customer service. Contacted 4 times ans never received a response so had to call again. The iPhone app no longer displays interior lighting since the in-sauna tablet updated a week or so ago under lighting preferences - interior lighting disappeared so you have to be inside to turn on and off - the iPhone app now only lets you choose exterior lighting. Spent 55 mins trying to trouble shoot and was told the software developers will have to fix and would be done in 3-5 days. Its been 5 days and not 1 thing has been done. No excuse for not having a software fix for this issue that impacts iphone users. Be better - do better! **Developer response:** Thank you for taking the time to share your experience, the interior lighting on the iPhone app was confirmed and has since been addressed. Please update your in-sauna tablet to version 4.1.0. After that, close and reopen the mobile app, and the interior lighting option should return under lighting preferences. We’re sincerely sorry for the delay in communication and appreciate your persistence in following up. Your feedback is a strong reminder of how important both functionality and follow-through are, and we’re actively working to improve on both fronts. If you need any support with the update or have additional concerns, our Customer Care team would love to help. ### 1/5 — App doesn’t connect *2025-03-04, version 3.2.0* App rarely connects to the sauna, sauna takes forever to get hot and seems to never get above 110 degrees even after 2 hours. I wish I knew this before purchasing. ### 1/5 — Doesn’t work! *2025-02-23, version 3.2.0* Have an amplify and it claims to have an audio feature. Doesn’t work! Not intuitive. East of time. ## Most praised reviews (10 highest-rated) ### 5/5 — Love this app *2026-07-25* I love my Sunlighten MPulse Sauna and use it everyday! The app with the new remote access is an excellent upgrade. Thank you Sunlighten team for your excellent product line and customer support. We appreciate you! ### 5/5 — Best part of my daily routine *2026-06-30* I absolutely love my Sunlighten sauna. I’ve had it for over 2 years and use it almost every single day. The app makes it easy to fit in my routine. I love that I can start my sauna from the gym so it’s hot and ready to when I get home. Thank you Sunlighten! **Developer response:** Thank you so much for sharing this with us! We’re honored to be part of your wellness journey and love hearing that your Sunlighten sauna has become such a consistent part of your daily routine. It’s wonderful to know the app is helping make your sessions even more convenient. Thank you for your continued support and for being part of the Sunlighten community. We’re grateful to be on this journey with you! ### 5/5 — It’s hit the prime time! *2026-02-18* I got my sauna about 2 years ago and was happy to see an app for it. Unfortunately, it was terrible. It had trouble connecting from the next room let alone from outside the house. It couldn’t control the lights effectively and so I gave up. Deleted the app and just used the wonderful sauna manually. Fast forward to today 2/26, and I went down for a sauna and there was a tablet app update. I loaded it and it wanted to connect to my app. I uploaded the app and noticed immediately that things are different. The app is much smoother. You can actually turn the sauna on from miles away and the both the sauna and color lights can be turned on as long as you leave the color lights on on the tablet and turn them off with the small chromo remote. If you haven’t tried the app since 2025, you should now. It’s all that we’ve been waiting for. **Developer response:** Thank you so much for sharing your update and for your patience as our team worked to improve the app experience. We’re truly glad to hear you’re noticing a smoother, more reliable connection and getting more out of your sauna experience. We’re also excited to share that we’ve just released a new update that expands remote access range, making it possible to start your sauna from even further away, whether you are at work, the gym, or out running errands. Our hope is to make it even easier to come home to a sauna that is ready when you are. Thank you again for sticking with us and for being part of the Sunlighten community. ### 5/5 — Great start *2025-11-26, version 3.2.0* A sauna after waking up, followed by a hot, then cold, shower is a great start to my day. I’ve noticed improvements in skin health, and a reduction in aches - especially after hard exercise the previous day. An important help to wellbeing. ### 5/5 — Believe *2025-10-10* We have had the believe unit for approximately 1.5 months and are very happy with our decision would do it again .Looking forward to to updates hoping for more programs **Developer response:** Thank you for taking the time to share this, and we’re so glad to hear you’re happy with your Sunlighten mPulse Believe sauna and would choose it again. We appreciate your feedback on wanting more programs and continued updates. Our team is always working to enhance the experience and expand functionality over time, and input like yours is incredibly helpful as we plan future improvements. Thank you again for being part of the Sunlighten community and for sharing your experience, we truly appreciate your support. ### 5/5 — Great sauna *2025-08-23* App is great. Sauna is amazing. Don’t really understand alll the poor reviews. Everything I have asked it to do it does . Kind of life changing honestly. **Developer response:** Thank you for taking the time to share this with us. We truly appreciate your support and are so glad to have you as part of the Sunlighten community. It means a lot to hear your experience, and we’re honored to be a part of your wellness journey. We’re always here if you ever need anything or have feedback as you continue using your sauna. ### 5/5 — Day 1 *2025-05-30, version 3.2.0* So far everything works well. Happy with it. Thank you ### 5/5 — Connection issues *2025-01-25* Apparently the connection problem is a feature which prevents you from starting the sauna away from home…. Really seems to defy the utility of it **Developer response:** Thank you for sharing your experience with us. We’re sorry to hear about the connectivity issues you’ve been encountering and understand how frustrating that can be. We've made improvements to the app since your review and we want to ensure you're using the most up-to-date version. Please give our Customer Care team a call at 877-292-0020x3, and we’ll be happy to assist you in troubleshooting and ensuring the best experience with your sauna. Your feedback helps us make valuable improvements. ### 5/5 — First month *2025-01-18* So far my MPulse 2 person sauna is great. I’ve had to learn the difference between the Finnish style with heat and the infra red functionality but I am satisfied that I got the best alternative for a home unit. I’m not super crazy about the iPad interface but that may be because I am an Apple guy. The construction and assembly is really high quality. Altogether I made the right decision to spend extra for a top of the line unit that I believe delivers a great experience. I’ll fill this in again after six months. Right now I love this thing! **Developer response:** Thank you for sharing your experience! We're so glad you're enjoying your mPulse sauna and appreciating the benefits of infrared therapy. It’s great to hear that the quality and functionality have met your expectations. We understand that transitioning from traditional saunas to infrared can be an adjustment, and we’re happy to support you along the way. If you ever have questions about the in sauna tablet or need any assistance, feel free to reach out—we’re here to help! Happy saunaing! ### 5/5 — So well-made. *2024-12-07, version 3.1.0* I’m a big guy and I’m very impressed by how solid this sauna is compared to everything else I looked at. The bench is rocksolid and no creaking or cracking. The tablet is great and watching YouTube videos makes the time fly. The oval experience is amazing. The programs are very helpful and the three person spa is the perfect size for just me so I can move and lay down. Worth every penny. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
