### 1/5 — Not there yet

*2026-07-28*

Does not work.

### 4/5 — Much better than the old app

*2026-05-01*

This is working much better than my old app. I am now able to adjust pH if needed from the app via some other upgrades. Luckily my spa was able to use the new system required to connect wirelessly as this one is 1000 times better than the old one. I only wish they added Bluetooth/speaker controls to the app.

**Developer response:** Thank you so much for your feedback on the app. We truly appreciate hearing that you're enjoying the new features! It means a lot that you took the time to share your experience with us. We hope you have many joyful moments in your hot tub!

### 2/5 — Needs excessive improvement

*2026-04-30*

The legacy app barely worked at all.   The new application seems to actually connect, however gives conflicting information on “too high chlorine” when the panel says it’s way too low with the SmartIQ.  It will randomly tell me that “water maintenance needed” but no clarification.   The lights have 20, 40, 60, 80, 100% settings, but my tub only has three levels, so there is that disconnect.  Not a decent value add-on at this time.

**Developer response:** Thank you for your feedback on our app. We appreciate your insights and recognize the importance of addressing the features you've mentioned. Please collaborate with your local dealer to ensure that you are using the most up-to-date software version.

To improve your experience with water maintenance, our knowledgeable team is here to answer any questions or address any concerns you may have. If you require additional service, please contact us at 800-999-4688.

Your input is invaluable to us, and we are committed to making the necessary improvements.

### 1/5 — Still not working

*2026-04-15*

I just got the connected spa kit 2 and while the hardware seems great, this app is simply not programmed well. Well, I am able to successfully connect the hardware to my home network every single time I go to set up a Spa, the app never manages to finish making the connection and see that the device is on my home network. This is frustrating because after the device connects to your home network, it stops showing it its own Wi-Fi network to connect to. That means you have to reset the device to try the set up from the app again. However, no information is given about how to go about resetting the device, and it simply says “Contact Dealer”. But of course, my dealer has been given almost no information either. Luckily I know my way around ESP32 chips, and after a bit of spelunking, I was able to figure out how to reset the WiFi on my hardware device. (Hold 2 until flashing blue, press 2 twice until flashing purple, then hold 1 until flashing white and it resets.). Sadly, despite trying a dozen times or so to go through the setup from this App, I’m never able to successfully add a spa. Funny enough, I can easily query the device using CURL on my home network and get the status of the spa and IQ system. This app just appears to be awful. Hopefully Watkins fixes this issue soon. In the meantime, maybe I’ll just write my own app and/or Home Assistant integration. Let’s see how long it takes them to fix the issues.

**Developer response:** Thank you for sharing your concerns with us. I truly understand your frustration, and I appreciate your familiarity with technology, which shows your commitment to resolving this issue. 

We genuinely want to help you and connect you with our tech team, who is eager to assist you further. I have shared your review with them, and they are confident that they can find a solution.
Please don’t hesitate to reach out to them at 800-999-4688, extension 8432. 

Our ultimate goal is to ensure you enjoy your spa experience and fully benefit from hot tubbing.  

We’re here for you, and we look forward to working together soon.

### 4/5 — Dealers and consumers were misinformed by Watkins

*2026-02-24*

I bought a new spa in September 2025 and the dealer confirmed I had the correct hardware for the new app, whenever it finally came out. I just tried to connect to the new app and am unable to do so. I called Watkins and they say a hardware change is required. Watkins please tell the truth to your dealers, so they can be accurate to the consumer. This is sooooo disappointing!

This is an update to my initial review.  I have worked with Watkins and the local dealer and they provided me with the updated hardware and installed it.  The new App is much more accurate and enables me to monitor and control my hot tub remotely.  Thank you Watkins for the Upgraded APP!

**Developer response:** Thank you so much for sharing your concerns with us. We truly understand how frustrating this situation can be. As it turns out, this new app requires new hardware as well. With this change, we are providing our dealers with the training and support they need to ensure a smooth transition.


I recognize that you need further assistance, and I want to assure you that we are here to help you through this process. 


Please reach out to our Customer Service team at 800-999-4688 or CustomerService@Watkinsmfg.com and have your spa's serial number on hand to expedite the assistance. 


Your feedback is invaluable to us, and we are committed to making your experience with the new app as positive as possible. Thank you for your understanding during this transition; we genuinely look forward to resolving this for you swiftly.

### 1/5 — What spa???

*2026-01-08*

What is the use of this app exactly? The legacy one is a joke that never works, and now this one doesn’t list what models works with? Also the legacy user/pass not working here…So many morons in this company!

**Developer response:** Thank you for sharing your feedback with us. We truly apologize for the confusion, as we understand how frustrating this can be. We recognize the challenges posed by our legacy app, and we designed the new version specifically to address those pain points and deliver a more reliable experience.

We released this app ahead of our new hardware launch with the intention of ensuring it would be ready for you when the updated hardware becomes available. However, we acknowledge that we could have communicated this more clearly: the app is specifically designed to work with the new hardware and, unfortunately, will not function with existing systems. We’re very sorry for any misunderstanding and are taking immediate steps to clarify this in our app description. 

Regarding the login issue, we understand how important easy access is to our customers. This app utilizes a different authentication system from the legacy app. If you decide to upgrade to the new hardware in the future and need assistance with the setup, please don’t hesitate to reach out to our support team at CustomerService@Watkinsmfg.com or 800-999-4688. 

We appreciate your patience and understanding as we work to improve your experience. 

Thank you for being a valued Hot Tubber.
