### 1/5 — Disappointed

*2021-06-10, version 1.2*

Only shows device page with minimal details of what my phone is, but already paid $1.99. The previews showed otherwise. Didn’t know if it could be fixed but this was the only option I had as to requesting a fix.

**Developer response:** Sorry for the bad UI/UX. You can swipe right to show the MENU which you can choose what info to show.
