### 1/5 — Doesn’t work at all

*2025-02-05*

The app will not connect to the camera at all. I have tried 10+ times and it says unable to connect every time.

### 1/5 — App has bugs

*2024-01-01*

I’m not able to transfer images to my iphone from the t1290.  It shows no error codes just keeps resetting

### 3/5 — Could use a good update

*2023-11-22*

The WiFi function takes too long and doesn’t always connect on the first try. The UI is clunky. Klein can make a great product, why not a good app to accommodate them?
