Your apps stay blocked. A solved chess puzzle opens one of them for five minutes. ZugZwang turns the reflex of opening an app into a move you have to think about. Choose the apps, categories and websites that eat your day. They are blocked at once and stay blocked. When you open one, the block screen offers one way through: solve a chess puzzle. HOW IT WORKS β€’ Pick what to block with Apple's Screen Time picker: apps, whole categories, websites. β€’ Opening a blocked app shows the block screen. Tap "Solve chess puzzle". β€’ Solve it and collect five minutes of that app, or of your whole list if you prefer. When the time is up, the block comes back on its own. β€’ The first wrong move fails the puzzle. The solution then plays out on the board, and a failed puzzle never unlocks anything. A RATING THAT IS YOURS β€’ Three puzzles during setup find your starting rating, from beginner to strong club player. β€’ Every puzzle after that moves it, like an Elo puzzle rating. Puzzles are served around your level, so they stay hard enough to make you stop and think. β€’ 20,000 rated puzzles: mates, tactics, endgames, promotions. β€’ Endless puzzles on the Puzzles tab, with filters for kind and length. STRICT MODE With strict mode on, removing an app from the list or turning strict mode off needs a harder puzzle or a 24-hour wait. Adding to the list is always allowed. YOUR PHONE STAYS YOURS β€’ You can always turn blocking off. β€’ Your rating and progress are saved to your account (Sign in with Apple or Google), so they move with you to a new phone. β€’ Which apps you block stays on your device. ZugZwang never learns their names. β€’ No ads. SUBSCRIPTION ZugZwang Pro unlocks the whole app. Choose a monthly or a yearly subscription.
