### 1/5 — Worse than garbage

*2026-06-07*

This app is infuriatingly terrible. Every time you want to use the device you have to delete the app and redownload it just to get it to connect at all. Then, once you do have it connected it keeps disconnecting itself every 5-10 seconds and you have to fully restart the device every time. There’s a very specific order you have to turn everything on or it won’t work. And there’s no indication of that anywhere, you just have to trial and error until you get it (open app, turn on device, turn on WiFi, go back to app, connect the camera) absolutely garbage. I hate this device so much.
