chainbreak

A habit tracker built around the “don’t break the chain” idea: pick a habit, click each day you follow through, and watch your streak grow.

You can create as many chains as you want — each one shows a four-week calendar where you mark off days. The app counts your current streak so you can see at a glance how you’re doing.

All your data lives in your browser’s local storage. Nothing is sent to a server, so your habits stay private. The tradeoff is that clearing your browser data will erase your chains.
