Had trouble with connectivity, so I had to have an upgrade performed in order to connect to the app via WiFi. I wish there were more options to run the spa for an hour vs. 15 min., because some chemicals require the spa to run for at least an hour to circulate them. Also wish there was an option to have only one color for the lights, and not the constantly changing ones. This app is pretty basic, but I do like being able to control the spa remotely. It would also be nice to have some way to monitor my chemicals… I have a Crystal Water monitor for this purpose. ### 2/5 — Just OK *2026-04-18, version 9.0.41* It’s nice to be able to adjust the temperature and filtration cycles. It’s a bit maddening that you can’t reset the monitor on the clear ray, water change, or filters until the time runs out. I change my water more frequently than the monitor and it’s pretty useless if you can’t reset. ### 1/5 — Terrible App *2026-01-29* This app is terrible especially considering how much it cost me. Jacuzzi has been no help and neither has SmartTub. At best it monitors the temp but now I am unable to even get into the app. One day I could the next I couldn’t and nothing changed as far as id or password. Have only had the app about 4 months. It worked for a couple of weeks and then have had nothing but issues. It says the date is 2018, constantly tells me the internet connection is bad, which is not my Internet it’s whatever network they set me up with. Jacuzzi pawns it off on SmartTub and SmartTub refers me to Jacuzzi to have someone do a service call. They tell me to find the module and see if it’s loose or they want me to pay to upgrade the network. Total garbage so far and no one takes accountability. DO NOT waste your money on this app. **Developer response:** We’re sorry for the bad experience you’ve had with the app and SmartTub support. Our support team is there to help when possible.

However, it rarely allows me to log in or connect to my hottub, even when standing right beside it with a strong wifi signal. Sometimes if I attempt to log in 20x in a row, I will get lucky and it will connect to the tub, allowing me to change temp etc. But usually it says ‘cannot log in’ and when I do log in, it says ‘no connection’. Too bad! ### 3/5 — Good, but c’mon!!!! *2026-01-05, version 9.0.2* It’s works well enough but has one MAJOR flaw and hasn’t been ‘fixed’ and I’ve waited years….how can it not have timers built in?!?!? Seriously. Crazy! Can’t be that hard to add a 20 minute countdown timer NEXT TO THE TOGGLE BUTTON - every time you start a jet by hitting the ‘switch’ toggle. Each toggle gets its own timer. It’s stunning and SO FRUSTRATING that this hasn’t been addressed. ### 2/5 — Application désuète! *2025-12-24, version 9.0.2* Cette application est tellement basique et désuète s’en est risible… j’ai payé pour trois ans parce que j’en ai vraiment besoin, mais je trouve vraiment dommage de payer pour quelque chose d’aussi poche! ### 2/5 — Poor quality *2025-12-06, version 8.9.7* Usually is pretty random at connecting or saving changes. It’s usually delayed for temperature data and SpaSense. It’s not even an overly complicated app. Not sure why it’s so clunky. ### 1/5 — Doesn’t work at all *2025-11-08, version 8.9.7* $20,000 hot tub and the app literally has never once been able to connect or manage any feature of my tub. Complete garbage ### 3/5 — We like this app but it has some flaws especially for paying the price we pay for it. *2025-10-21* My swim spa somehow disconnects because I notice the Temperature drop so I check the app and have to login again. Shows it’s disconnected and then trying to connect to WiFi will show it gets connected and gives me an error. This happens all the time. My swim spa then gets cold and won’t increase at the panel. Very frustrating to pay for this service and it’s constantly logging you off and disconnecting. Similar review has same issues. We like it a lot but have nothing but issues.. **Developer response:** Sorry for the experience you’re having with the SmartTub app. Please contact our support team with details of what is occurring, and they’ll be happy to assist you in getting this corrected. Please email them at support@smarttub.net, or you can call 844-602-6066 option 1 during our hours of operation, Monday through Friday from 7 AM to 4 PM Pacific. ### 3/5 — Great when connected *2025-09-23, version 8.9.4* I love it enough to keep paying for the connection. The problem with this app is that it always ends up with the timeout and unable to authenticate again unless logging out and log in again. After so many years this issue is still NOT fixed. ### 1/5 — Disappointing app *2025-09-22, version 8.9.4* Time cannot be fixed creating issues and additional cost. We don’t understand how such a simple app is poor quality including repeatedly having to turn off and on. The jacuzzi spa is a top end product but supported by poor products and support. They are quick to take your yearly fee though. Don’t bother buying jacuzzi if you think you are going to get a better product. Do better ### 1/5 — Flakey app for an expensive feature *2025-09-15, version 8.9.4* I’ve used this app for years to control my hot tub. It repeatedly encounters errors communicating with the back end. Recently it can’t even log in and the support team is unable to resolve this issue. Until they fix things and get their act together do not buy this! ### 1/5 — Equipment outdated expensive. *2025-09-09, version 8.9.4* My tub is only 7 years old. Now the smart tub devise is outdated and I can’t use the smart tub App Need to pay $500 to buy a new smart tub modem so I can monitor my tub. Not impressed with the company. ### 2/5 — Used to work *2025-09-08, version 8.9.4* I paid for a 3 year cellular subscription a few months ago but the past few weeks I can hardly ever get it to work. I just get the red error at the top of the app suggesting I turn it off and on again which I have done many times. Why has the reliability got so bad Frustrating after paying for 3 years! I’m based in Suffolk UK. ### 1/5 — Expensive and doesn’t work *2025-09-02, version 8.9.4* The app rarely connects and requires constant reinstalls, constant rebooting the hot tub. It is buggy and flawed and they have the gall to charge an annual subscription fee. Just walk outside and press buttons. ### 2/5 — App buggy; not implemented well *2025-08-25, version 8.9.4* I have to log in every time I use the app. Often the app doesn’t know it’s logged out and any action will error out until I force close and open again. The energy reporting doesn’t work. A graph displays and then immediately disappears. Light scheduling doesn’t support sun up / sun down times, and constantly needs to be updated to reflect day length changes. ### 3/5 — Find the Logout screen game! *2025-08-21* Enjoy overall functionality. We use over wifi. But, seems to lose function every time phone screen sleeps which is issue mainly because to log in one must first close a warning screen, then an error screen, then search for logout button which requires tapping user name, then name again at top of next screen, then logout, then login to resume use. **Developer response:** Thanks for sharing your experience. We weren’t able to reproduce the steps you stated. We’d like to investigate your report.

Recently But the past few months my tub would always say offline. I would log in and change a setting like the temp or check the water days remaining or to set the time or calendar after a power outage, it would just say the tub is off line. This has been the case for months now. Now when I try to log in its says server timed out please try again. I cant even get logged in. In the beginning this app was so useful and great to use. Now I’ve paid for a annual service I cant use. Pretty bummed out. Taints the ownership of my tub. ### 3/5 — Buggy *2025-08-03, version 8.6.9* The app keeps reverting to incorrect time, causing the spa to heat during peak power prices. Also, why not have an ability to force heating at specific, off-peak times? This should be as easy as entering the times you want it to heat without unnecessary complications. ## Most critical reviews (10 lowest-rated) ### 1/5 — Never Works *2026-08-01* This app is absolutely horrible. I have to log in every single time I open it, and most of the time it takes multiple attempts to do so. And now it keeps telling me my hot tub is offline…despite the screen on said hot tub showing a connection to our WiFi. I have so many free apps with no subscription costs that work a million times better than this garbage. And I swear each update makes it worse. The scheduling part of the app is incredibly confusing. I’m very close to cancelling my subscription and just using the control pad on the hot tub since that’s what I have to do most of the time anyway. When you charge as much as u do, maybe use that money to get someone who knows what they’re doing to build your app… ### 1/5 — Poor performance; poorly designed *2026-05-06, version 9.0.46* I have to log in every time I open the application. My login times out 50% of the time. Commands sent to my tub often time out. The scheduling side is confusing at best. I can’t control my exterior lights on their own schedule (jacuzzi 3xx series). The energy usage chart is buggy and most just renders as blank. All that said. The app does work sometimes. The alerts and reminders are nice. I’m giving one star. Mostly because it’s been three years, and nothing has changed. If anything; I feel like it’s gotten worse. ### 1/5 — Worst App Ever *2026-03-24, version 9.0.29* Do not waste your money on this app. Have had it almost 6 months with our brand new swim spa and it’s worked maybe a month total. Currently it says my temp is 32 degrees F when it’s actually 95. Customers service is not help other than if I send an email complaining the app magically works for a few days until it doesn’t again. Jacuzzi bus no help either. Not worth the price paid, it’s not worth it even if it was free. Garbage. ### 1/5 — Good luck accessing SmartTub *2026-03-10, version 9.0.29* Can’t even login the 1st time…accepted the code I was emailed but that’s as far as I got…useless app…don’t bother ### 1/5 — SmartTub app not accessible for visual impaired users anymore *2026-03-10, version 9.0.29* I downloaded the SmartTub app when I purchased my Jacuzzi hot tub. I am visually impaired and changes have been made to the app that doesn’t allow me to use it anymore. I reached out on the app for help and sent three emails but I have received no answer. Please make this app accessible again for visually impaired users. It is a inconvenient and a hassle having to depend on people to control your tub for you. ### 1/5 — Completely Unusable *2026-03-06, version 9.0.29* Can’t Even Enter the Verification Code I recently bought a new Sundance Altamar 880, and the installers told me I’d be able to control my spa through the SmartTub app. Unfortunately, the app has been nothing but problems. It was missing from the App Store for a while, and now that it’s finally back, it still doesn’t work. I’ve tried signing up multiple times using three different email addresses. The app sends a verification code, but the code field doesn’t accept any input at all — tapping the numbers does nothing. I deleted and reinstalled the app three separate times and made sure to clear all data, but the issue never changed. Right now the app is completely unusable, and I can’t access any of the features I was told would come with my spa. Very disappointing for a brand‑new product. ### 1/5 — Shame on Jacuzzi! *2026-03-06, version 9.0.29* This has to be the worst premium brand app ever made. It’s so buggy I could not even get past the sign up process. Completely useless. ### 1/5 — Chemical balance button is gone *2026-03-04, version 9.0.29* The last update seems to have removed the button I tap to see the chemicals, like chlorine adding advice. The button is just not here anymore… now I have to measure my chemicals with a strip like a savage, canceling out the entire purpose of this app. ### 1/5 — Needs work *2026-01-30, version 9.0.24* Apple Watch app no longer supported. Please bring it back. Have to sign in each time launching the app. Expensive yearly fee. ### 1/5 — So many bugs *2026-01-29, version 9.0.23* So many bugs, I can’t even get logged in. Text fields have errors, reset password errors, horribly designed, wrong color for input boxes. C’mon it’s 2026, just vibe code your way to a functional product! Embarrassing app for a $17,000 hot tub. ## Most praised reviews (10 highest-rated) ### 5/5 — Works even better with new module *2024-12-16, version 8.1.1* It’s great to be able to control ur hottub from afar and the new module with WiFi makes it even better to use this app ### 5/5 — Great App for SPA Monitoring *2024-11-20, version 7.9.0* Great Customer Service and app provides great monitoring and adjustment for APC if needed via cellular network. ### 5/5 — Great App, annual fee is well worth the Peace of mind! *2024-10-31* Installation was a breeze and is super user-friendly. I live in a cold climate and love the convenience of just grabbing my phone to check on our hot tub anytime, day or night. I also use the app to control the lights and jets before we head outside to soak. It’s really handy to have this control. I highly recommend the app and subscription service! **Developer response:** Thank you. ### 5/5 — Its a great app *2023-10-26, version 7.1.5* Its getting better by the day. I use to have a lot of connection issues in the past.. its pretty stable now. ### 5/5 — Love the new smart heating feature *2023-07-26, version 6.6.7* I’ve had this app for over a year and have found it really useful to be able to control my Jacuzzi J475. The signal is very stable, which wasn’t the case with my previous tub (the app was WIFI) and meant sometimes connection was rubbish when I needed it In the last few months there’s been a cool new feature released which is helping monitor/manage energy use really well. It will build the most energy efficient heating schedule for when I want to use it. All in all a very cool app that I didn’t realise I would find so valuable when I purchased the tub. ### 5/5 — Great app *2023-07-05, version 6.6.6* The app is great for if you are away from home a lot like me. The energy use monitor is a brilliant feature. Definitely worth having with your Jacuzzi hot tub purchase. ### 5/5 — Simple to use and helps me save money *2023-06-29, version 6.6.6* Love how I can still connect up to my hot tub via 3G when I’m away from home! I also really like the Smart Heat mode feature. Scheduling in the time I’m going to use my hot tub and seeing the est energy saving is great, plus it makes me look forward to a lovely soak. 😍 ### 5/5 — Brilliant! *2023-06-12, version 6.6.6* Really useful for tracking energy usage and the added bonus of being able to operate the spa remotely so it can be ready as soon as I get home! ### 5/5 — Really enjoy the functionality of this app *2023-06-09, version 6.6.6* I love the functionality of this app, I can control many different aspects of this tub from my phone which is really handy! ### 5/5 — I love you smart tub app *2023-06-09* I love the smart tub app great features. I so happy to jacuzzi smart spa tub.I use this app every day in my house.I love being able to change my tub temperature turn on off the jets as well as the lights remotely .It has definitely saved me a lot of time and it super convenient.I highly recommend my other friends and relatives. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
