Grüning et al., PNAS 2023TacticLock locks the apps that pull you in. To open one, solve a short chess puzzle at your level. You get your break, and a little sharper every day.
How a lock works
01 / 03
TacticLock steps in before the feed does. Emergency access is always one tap away.
One short puzzle at your level. Find the move, or take a hint.
15 or 30 minutes, the length you set in your lock group. Then it locks again.
A pause that takes a little effort and teaches you something, instead of a wall you learn to click through.
A puzzle is a micro-learning pause. The small effort breaks the swiping reflex and switches on the thinking part of your brain, so you choose instead of react. And you leave a little sharper than you came.
