nopin is a small web tool that works alongside iOS Screen Time / App Limits.

It increases the friction of bypassing limits by turning a 4-digit PIN into a hard-to-memorize, reusable input sequence. You simply follow on-screen prompts to enter the PIN step by step. The sequence can be saved and replayed when needed.

I built this because I wanted something like Cold Turkey on desktop, but for iOS.
