Cool App!

The app is cool! It would be nice for the chess lock app to automatically pop up when a selected locked app is tapped. It would be nice for the selected app to pop up unlocked as soon as the puzzle is solved for the desired time selected. Otherwise, It has been a more productive distraction.

I downloaded this app and Opal in the same day. Despite all the hype, I found this app way more useful than Opal. Instead of a quick way to bypass with breaks, my lazy self had to question if it’s worth pausing to solve a chess puzzle. There was one time where I decided it was “worth the investment” to go solve the puzzle… but the other times, it has kept me in-line. I can’t explicitly explain the logic of why it works, but my brain digs it. Great work!

Good concept, bugs make it useless

Some of the chess puzzles don't work properly (the opponent never reacts), and once the app gets stuck, it never gets unstuck, making it useless.
