### 4/5 — Great but one thing

*2025-08-06*

Hi! So far I love this app! The only thing that I wish for is a way to disable Stevebot in settings. He is kinda annoying sometimes. Other than that I love it!

### 1/5 — Ok

*2020-12-23*

It’s ok but needs more free stuff because I tried to play it and it only lets me play three games 🥺

### 5/5 — It is the best app

*2020-10-28*
