### 1/5 — Doesn’t work

*2026-08-07, version 14.1.0*

If I could give 0 stars I would.  Can’t even create an account to hook my water heater to the app.  Same error message every time.  It says that there’s an error creating an account, contact customer service or try again.

### 3/5 — It works

*2026-08-02, version 14.1.0*

Seems to be stable now, hasn’t  “forgotten” my hot water heater for a while now.

Reason I didn’t give it more stars was that there was a feature to see how much electricity it used each day by clicking on the in-app chart.  Now you just have to guess based on their terribly scaled chart

### 1/5 — App already broken

*2026-07-31, version 14.1.0*

It doesn’t update. Have to quit and restart. At the moment it won’t let me log in. Account is there and I reset my password. 

AOSmith: fire your app developer. They make you look bad!

### 1/5 — Trash app doesnt connect

*2026-07-30, version 14.1.0*

No connection

### 1/5 — App, iCOMM Network Connectivity is terrible

*2026-07-26, version 14.1.0*

I’ve tried multiple times to use this app to register my new water heater & activate the iCOMM connection to monitor & manage the device. Typically, I often get an error message that’s coming from their server basically saying we’re experiencing problems, please try again later. Plus the DSN is hidden behind a plate which is not clearly mentioned in the user manual. Not a fan!

### 1/5 — Unusable

*2026-07-25, version 14.1.0*

Won’t stay signed in, not much functionality even when you’re in there, not worth the frustration of downloading

### 1/5 — Not intuitive to set up

*2026-07-25, version 14.1.0*

I have 15 smartphone apps on my phone.  This is the only one that I needed to call for tech support.  It first asks you to get the QR code serial.  No problem.  The it asks for the Icom module QR which I couldn’t find so I went to the help which had a picture of the location but it didn’t match anything that looked the same on my water heater.  I tried to connect it to WiFi like I have done with all of my other apps but it couldn’t find the icon module.  Called tech support which they were really great and walked me through getting it set up.  A little better app and they can avoid calls to tech support.  The app itself is weird.  There isn’t any refresh that I can see and I can’t tell if I am actually communicating.  I think I am but it would be nice to see an indication.  I googled it and supposedly there is an indication but I can’t find it.  Maybe it was on a previous version.  It seems like the person that programmed this app has never used a Smarthome app before.

### 1/5 — Major infrastructure issue

*2026-07-24, version 14.1.0*

I hate to be critical, but this app barely has any feature. More importantly, constantly log user out of the app. I also use Home Assistant and Home Assistant constantly report connection being unavailable. This signals, there are some major infrastructure issue associated with this whole setup that needs to be addressed. This kind of issue has long been resolved many times over. Please fix

### 1/5 — Barely Workable App

*2026-07-22, version 14.1.0*

Update: July 2026. Dropping a star since they still haven’t fixed the very basic interface problems. Various buttons are still blank and non-functional. The app clearly isn’t a priority for the company. 

It lets me change modes remotely, so that’s good I guess. But the electricity usage tracking chart is pretty much useless. And various buttons, including the back button when you go into settings, simply turn white and don’t work sometimes. Very poorly programmed and QA’d. As such, don’t trust that it will do what you want when you need it to.

### 1/5 — Doesn’t work

*2026-07-21, version 14.1.0*

Went through the steps to both scan and manually enter my water heater multiple times with no success.   Not wottth the trouble
