### 1/5 — Needs major UI update

*2025-12-29*

We use this for our home in Austria for lighting and heat. The UI not at all useful and inside the Heinzkurve Test section the app is turning gray (freezing) every few seconds. We use Loxone in FL which is miles better.

### 1/5 — Horrible App

*2023-09-23*

I’ve nearly 25 years of Web and medical device and consumer electronics experience in usability and I find this app a nightmare to use. It’s a horrible mix of setup capability and user interface. It seems exceptionally clunky to use and entirely unclear what anything does or how you use it. I can’t find any documentation for the user either. Having spent over £2K to install Control Touch to my home heating system, I’m deeply disappointed by the app which was the whole purpose of making the change. Any system is only as good as its user interface and this one is awful.

### 1/5 — Don’t bother

*2019-09-23*

App hasn’t been updated in over a year. Hard to program, keeps crashing and no support. Would not recommend.
