Really is like a cheat code

(Don’t use it to cheat obviously) but for analyzing your finished games, it’s a great tool to have in your pocket.

Response from developer

Hi Gabriel! Thank you so much for the fantastic review. We absolutely love your feedback, having a Grandmaster-level engine sitting in your pocket really does feel like a superpower sometimes! You hit the nail on the head regarding the use case. We built this app specifically to be the ultimate learning tool. Being able to instantly analyze your finished games while the moves are still fresh in your mind is one of the fastest ways to improve, so we are thrilled that the app is helping you do exactly that. Thanks for your support and recommending us as a great tool to have in your pocket. If you ever have any ideas to make your analysis even better, just let us know!

Fast way to check my moves

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.

Response from developer

Hi Jay! Thanks for the great review. Eliminating the process of manually setting up pieces was our #1 goal with this app, so we're really glad to hear it's saving you time. Good luck in your chess climb!

Scam

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
