### 5/5 — BROKEN DO NOT BUY

*2021-02-20*

Waste of money. Again, 5 star so they don’t hide my review. Just like the first version this one has stopped working. The money I wasted I on these two sister apps could’ve gone to other stickers. Waste of space. Fix the app or just remove it so we can all get our money back.

### 1/5 — Doesn't work with iOS 14

The stickers show blank screen now. Can't use them :(

### 5/5 — IOS 14 Broke It
