I am regularly confused as to when the water heat levels were last synced so I cannot tell if they are accurate or not. It would be great to display that on the home page and give feedback (like a reload button) to refresh and state if it fails. Overall, a pretty bad customer experience when so many other smart home apps are well made and intuitive. I will probably search for another manufacturer in the future that has a better working app ecosystem. At least the energy usage probably works well. In fact, I tried to submit this feedback from inside the app and it was broken and wouldn’t allow me to submit, so I came here to the App Store. ### 1/5 — Constantly having to re-add water heater *2025-01-17* Constantly having to re-add water heater ### 1/5 — Horrible app, great water heater *2024-11-18, version 13.0.1* Although I like the actual water heater, this app is junk. 1. It always shows I only have 10% of hot water in the tank at all times; 2. The unit comes with a water leak detector module that sits in the bottom of the pan, so if the tank leaks, the unit sends me an alert . This is all well and good, but the alert goes to the app on my iPhone and just sits there. There is no push notification like a text message, email or automated phone call. Does State expect me to check my app every day to see if my water heater is leaking? I called the customer support line and they said “oh, we don’t control the app, that’s a third party that we have no control over.” What?? You can’t control (or improve) your own app?? 3. In the Notification section of Settings on the iPhone, there is no State app showing up. I can’t change the notification setting because there’s no app to change. To the State company: If you’re reading this, look at the poor rating of this app. Don’t you think it’s worth having a developer MAKE IT BETTER?? ### 1/5 — Lacking and inaccurate *2024-10-20* Despite having plenty of hot water, our app is now reporting 10% - 20% hot water at all times. ### 1/5 — New App Issue *2024-10-16, version 13.0.1* The new app does not accurately so hot water available. It never goes above 10%. ### 1/5 — 13.0.1 still broken *2024-10-15* Congratulations to the software team for making it even more obvious that the app is broken. Now there is clarity in the color scheme to be really sure that the app is always reporting that my water tank is empty or at 10%. And support has still never responded to my queries despite the 24 hour turnaround promise. ### 1/5 — V13 busted *2024-10-12, version 13.0.0* While I appreciate the attempt to show real-time status, the feature does not work. It never shows more than 20% full which (I hope) is not accurate. It also regularly looses connection with my hot water heater and requires a manual re-pairing. This app has been abysmal since I purchased the water heater a year ago and has not improved with subsequent releases. ### 1/5 — Disappointed and underwhelmed. *2024-10-12, version 13.0.0* App constantly claims that it is unable to connect with State’s network. Updated to ver. 13.0.0 and now heater only shows no hot water or only at 10%. At least able to switch between modes. The app certainly needs more work. ### 1/5 — Water heater removed *2024-10-01* Every bigger update removes my water heater. Has happened at least 3 times in less than 2 years ### 1/5 — New version 13 DOA *2024-09-27, version 13.0.0* Logo screen and that’s it… ### 1/5 — Doesn’t Work *2024-06-29* I’ve used this app for a year now. At first it was okay, granted it made me sign back in a few times. Now, however, it dropped my water heater from the app entirely and I am unable to add it back. ### 1/5 — Update this App! *2024-05-25* Exactly what the other reviewers have said: - Real time status of heater, is it running? In what mode? Is the compressor running or just the fan? - Reset/restart feature in app, this is the only way to fix most issues - like when heater gets stuck in a mode - and the only way to restart is to flip circuit breaker or pull out and reinsert service disconnect. Alternatively add an automatic system reboot you can set to happen daily at 3am. - Detailed information in the electrical usage. - Actual temperature of the water and the intake air temp to know if you are close to the operating min/max of 45/120. (120 is a very typical afternoon temp to hit in a Florida attic- why so low for a max? Put that heat into the water!) - Push alerts your water is under a set temperature so you know to cycle the power before you get in the shower. - Why just in an app that is down 1/5 of the time? No website access to the heater? None of this is that hard. The data is apparently available just not usable/visible. ### 1/5 — Useless *2024-02-19, version 11.3.5* This app is inexcusably bad. Even basic functions such as ending “Vacation Mode” don’t work. Supports suggestion “Press the button on the water heater or do a Hard reset”. Well since the point of the app is for use when I am not there, then there is no point to the app. Energy utilization works about 50% of the time. Increasing the temperature only works if you had previously done it at the panel. There is no way to tell the actual temperature of the water. Honestly, had I known how poor the software was I would have bought a less expensive hot water heater. ## Most critical reviews (10 lowest-rated) ### 1/5 — Terrible App *2025-10-07, version 13.0.7* This app is okay when it works, but my water heater is constantly being deleted from my profile or if it is there, half the features don’t work at any given time. Fix the bugs and this would be great. ### 1/5 — Signed out, forgot it all *2025-09-23, version 13.0.7* Don’t rely on this app to control your water heater when away, because sometimes it will decide to sign you out and when you sign in, it says “Add heater”. And the only way to do that? Physically scan the sodding QR code that’s on the device you’re trying to remotely control. REMOTELY. Come on developers, do the basics. Oh, and if you could also expose it to Apple HomeKit and Google Home, or better yet, Matter, we’d all like that too. ### 1/5 — 13.0.7 forgot my water heater *2025-09-21, version 13.0.7* Asking me to add my water heater again. ### 1/5 — Terrible app *2025-08-24, version 13.0.7* Usage info is horrible , graph has wrong date for today, not able to get accurate info for sorting by period, shows lifetime usage with limited month, couldn’t be any less helpful. Just the day info is and frankly probably not. This app needs complete fixing! Like water heater but mfr should not have any app at all if this is all they can offer. F- rating for developer. ### 1/5 — Horrible app *2025-06-25, version 13.0.7* Horrible. Constantly logged out while using the app. Every couple of months water heater is removed app. 2 water heaters fail in less than 3 years. ### 1/5 — Garbage app *2025-04-28, version 13.0.2* This app is total garbage. It frequently drops my water heater forcing me to set it up again. Sometimes it reads the wrong data for volume of hot water. Also there are days at a time when the app can’t reach the server. The water heater is fine, but this app has not gotten better in well over a year. Needs a lot of improvement. ### 1/5 — Horrible app *2025-04-22* Unusable. Constantly having to re-add water heater, constantly getting signed out while in the app ### 1/5 — Worst app *2025-04-21, version 13.0.2* Where to begin? The app is unintuitive and hard to configure. It also signs you out occasionally, making you re-register with a long serial number to type in. It also doesn’t send important info via notifications like a major issue with the water heater. Huh? Finally, there was a “known issue” with the app showing the wrong water temperature which lasted at least a month or longer. Poor execution all around. ### 1/5 — App Doesn’t Work At All *2025-04-09, version 13.0.2* App is designed to do 2 things: scan a QR code and register a new hot water heater. The scan didn’t work at all and entering the serial number manually also didn’t work. The last thing was the customer service phone number referenced in the app also didn’t work. I had to go to the website to find a good number to call to complete the registration. Come on folks!!! How hard can this be? Even kids are writing mobile apps these days. ### 1/5 — Constantly drops added heaters *2025-02-23, version 13.0.2* The app constantly drops added water heaters, requiring you to go through the effort to re-register your device. How on earth is that information not just stored with the user name? Junk app. ## Most praised reviews (10 highest-rated) ### 5/5 — Great App *2018-06-08, version 3.0.22* It makes it easy to see if a water heater is under warranty and check the part numbers. ### 5/5 — Easy and Useful *2013-03-06, version 1.0* Simple, quick, and easy to use. Good for end users too...no account required. ### 5/5 — Fast *2012-12-14, version 1.0* This app shows me the warranty status much faster than the web with detailed supportive info. A must for any contractor ### 5/5 — Great *2012-08-10, version 1.0* Simple works great! Easy to use!! ### 3/5 — 13.0.2 reverted to working again *2024-12-31* I have to give credit to the app team for recognizing their failures and reverting to an older UI that works. ### 2/5 — Keeps forgetting my device *2025-09-12, version 13.0.7* When properly logged in - useful app in terms of settings and monitoring. However - it cannot remember my device. It remembers my login but every time I w add my to use the app - have to “add my device”. ### 2/5 — Two main issues *2024-10-27, version 13.0.1* I hope these can be fixed. One issue where the display of the percentage of hot water available is switched with the available cold water. When we don’t use hot water it display 10% hot water available. When we use a lot of hot water it displays a higher percentage of hot water available. Second issue where the usage data always reads “Unable to load energy usage data” ### 2/5 — Not accurate *2024-10-16, version 13.0.1* App doesn’t show accurate estimate to how much hot water is left. Specifically doesn’t work right for heat pump water heater. You would think they would test this. Seems like others with a heat pump see the same thing - only shows 10 to 20% hot water available. ### 2/5 — Shows tank always empty *2024-10-05* Ver 13.0.0 is broken. It always shows the hot water level in the tank at 10% or empty. Sent email to app support and was promised 24 hour response. Have not heard back in a week. Disappointing. ### 2/5 — Very basic app *2024-02-25, version 11.3.5* A useful, but basic, app. Both UI and functionality need an upgrade to meet modern consumer expectations. As other reviewers have said, product is a premium water heater with a not-so-great app. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
