5 stars: Definitely an underrated visualization app! Not the puzzles themselves but the practice it provides is invaluable. I've tried playing blindfold before and it's a challenge -- with this app I can practice memory, board vision, and tactic patterns in a manageable way. I especially enjoy the option to make the practices progressively harder. This is now part of my daily training!
5 stars: This App is amazing! Customizable blindfolded chess puzzles!!! Complete opening repertoire taken from millions of games from lichess and Master level games. Second to none visualization training to aid in seeing several moves ahead and not making blunders. This app is a great addition to have in anyones library!
4 stars: Very valuable app -- I would give it 5 stars, but it has an irritating glitch. It fairy regularly tells me my solution is wrong, when in fact there are multiple solutions. The app's
4 stars: The app is very good for chess visualizing training but it could use a better design.
3 stars: It's good. But sometimes there's more than 1 way to do the puzzle. But the game won't accept it unless you do it the only way the games been programmed. On 1 board it asked me to mate in 2. I found a mate in 1, but the game disallowed it.
2 stars: The idea could be brilliant, but the UX is very unintuitive. I'm not a chess beginner (2000-2100 tactics training rating on lichess), but I have no idea what's going on here. It's simply hostile and unpleasant to use.
