No spaced repetition
There are thousands of puzzles, which is great, but it takes forever to get through them all and there’s no way to mix in what you’ve already tried into what you’re working on next to ensure the learning sticks the way this program is laid out. There’s no way, that I can see, to even review just the puzzles you got wrong or just the puzzles you got partially wrong. There’s no way to build a randomized set of problems from multiple sections to use as a warmup. You can only build a randomized set of problems from the same section. You may as well just go to that section... This app is best if you just want to practice one specific mate in 2 tactic, like queen+ rook mate in two, *hundreds of times in a row.* Or ALL the types of mates at once. Very repetitive and tedious. Not if you want to try 5 or 6 types of mates in a sample of 100 in a quick practice session. You have to choose “all mates” rather than a group of specific mates you’ve been working on. And not if you want to practice just the puzzles you missed. It’s also not clear how this mate in 2 app is different than the previous chess king mate in 2 app.
