### 1/5 — Broken on iOS

This pack has been broken for months now, only a blank screen shows up. The other cosmic chemistry pack is the same. I want my $2 back :(

### 1/5 — Doesn't work with iOS 14

### 5/5 — BROKEN APP

*2021-02-20*

Gave this 5 stars so they won’t hide my review. The app as been broken for MONTHS with no fix. I did not spend 2 bucks not to be able to use it. I could’ve gotten a different one. Would be boss to have it refunded so I could do just that. Or...yknow. . . Fix the dang thing????
