Anyone used the free Android chess program called Droidfish? It's a very well made program, uses stockfish to play and analyze.
You can set the stockfish strength too as a percentage.
As I'm kind of amateur in chess, wanted to check you're opinions - especially on playing strength - as even after toning it down, it takes time to calculate moves, and I couldn't beat it yet. I've gone down till 16% of Stockfish.
Also there are very few detailed reviews or discussions on it.
What's your thought about it?
