### 1/5 — Doesn’t work!

*2025-03-06*

This app immediately closes when I try to open it (?) and their support link on the Apple Apps search page warns that some one might be trying to steal my identity/information! FAKE APP! 🤬

### 5/5 — Awesome

*2025-01-24*

Great app. Hope soon will be option for the number of variations the engine analyse

### 1/5 — Can’t move the pieces

*2024-04-01*

Drag and drop is useless.
Maybe another mode to move the pieces would be helpful.
