### 1/5 — bluetooth also cannot connect the app

*2026-07-09*

what‘s the reason of  connection with app?how to solve it

### 1/5 — Terrible

*2026-07-03*

App just doesn’t work. I constantly try to connect and can never adjust settings or turn the device on via Bluetooth. The one time it did work the app interface was completely different and it saved my settings. It has not worked since and the app is essentially useless at this point.

### 1/5 — Bluetooth issue

*2026-05-30*

Still I have issue with Bluetooth connection with CERA+ PRO2

### 5/5 — Happy with the app!

*2026-05-20*

Works perfectly with my Ikape Kapo K2 portable espresso machine. Sometimes it has a little trouble connecting the first time, but otherwise no major issues using the app. Love all the flexibility, very straightforward, very easy to use.
