I'm a big fan of lichess's tactics training, because puzzles include both winning material and checkmate sequences, and the puzzles are taken from actual games.
Unfortunately this feature isn't available on the lichess android app. Is there some other app that meets most of these requirements?
- is free
- has no limit on number of puzzles
- has both checkmate tactics and material-winning tactics
- has sufficient variety in puzzle difficulty
- has a puzzle rating / gives you a tactics rating
Any recommendations are appreciated, thanks!
