A Visible Streak, Built on Real Consistency

Habit formation research consistently points to visible progress tracking as a meaningful motivator -- seeing a streak grow day by day creates a tangible incentive to maintain it, more concrete than just intending to "do better" without any tracking at all.

Missing a Day Resets the Streak, Not Your Whole History

The current consecutive streak resets to zero if you miss a day, reflecting the genuine pattern-breaking nature of a missed day -- but your total completion count across all time remains separate and intact, so one missed day doesn't erase the broader track record you've built.

Local and Private, With a Real Tradeoff

Your habit data stays in this browser's local storage, never sent to any server -- genuinely private, but also tied to this specific browser and device. It won't sync if you switch devices, and clearing browser data would clear your tracking history too.

Frequently Asked Questions

A streak counts consecutive days you've marked a habit complete, resetting to zero if you miss a day -- a simple, visible measure of consistency that's been shown to be motivating for habit formation in behavioral research.

In your browser's local storage on this specific device, persisting between visits as long as you use the same browser without clearing browsing data -- no account or server involved.

Yes, add as many habits as you want to track, each with its own independent streak and completion history.

Your streak count resets to zero for that specific habit, but your total historical completion count (separate from the current streak) remains, so missing a day doesn't erase your overall track record, just the current consecutive run.

For casual personal tracking, yes, but since this lives in local browser storage rather than a synced account, it won't transfer if you switch devices or browsers, and could be lost if browser data is cleared -- worth keeping in mind for anything you'd be upset to lose.
