There is a chess app on IOS that suggests you moves and warns you against obvious situations where you would lose your piece. It's using an old but still popular engine: https://itunes.apple.com/us/app/chess/id522314512?mt=8

I had most fun with this chess engine. Stockfish engine was not fun at all, it was playing like an "asshole" most of the time and when the AI strength is reduced it was like playing against a stupid "asshole". When playing against human you feel like your opponent is on something but against AI you feel like you run for your life. Mind you though, I am very amateur chess player, I play only recreationally.
