### 5/5 — Fast way to check my moves

*2025-12-04*

Does exactly what it says. It’s way faster than setting up the pieces manually so this is a huge time saver. The chess engine loads fast and shows the best move right away.

### 1/5 — Scam

*2025-11-27*

It was very buggy and kept crashing, but not only that it didn’t work at all. The scan feature both picture screen and actual chest set ups resulted in what seem to be just random weird positions, but even related to the actual picture or scanned board. I tested it over and over it does not even close. It’s like I said random it appears which is why I called this a scam. I requested a refund, of course.. this explains why there’s no way to experience or test it out before pain

### 5/5 — The actual only free chess engine

*2025-11-16*

I‘ve been scrolling though the app store for 30 minutes now and i just found this one. I expected it to be paid, but it‘s 100% free! 10/10 great for making your friends queston their life in chess
