Magnus is #1, but his app is not

Very poor app overall, you wont learn anything using it. There are no puzzles or anything like that. His tutorial videos cost $2 each, which you can find for free on YouTube chess channels. It costs $2 for more diverse difficulties. Even the evaluator or "Magnometer" cost $3. Like really?! You cant save games or scroll forward and backwards during a game. You can watch a replay afterwards, but thats about it. Its bug free and very powerful, but then again, I do have the Stockfish 7 chess engine, which is FREE.
