Diamonds don't form overnight. They are shaped by immense pressure and time. The habits work the same way.
With every check-in, you visually form your promise and your habit gets refined, until the coal you started with becomes a diamond that reflects your own growth, in real time.
Step 1
Pick the habit and how often it runs. Optionally stake tokens on it. Creating the goal generates a gem that exists only for that habit.
Step 2
Each day you prove the habit with a photo rather than tapping a box. Evidence, not self-report — the difference between a record and a hope.
Step 3
A friend you invite as referee approves or rejects the check-in. No referee yet? AI verification covers you in self-paced mode.
Step 4
Approved check-ins grow the stone through Coal, Forming, Formed, Radiant and Atomic. The gem only moves forward — a miss leaves it as it is. A staked token absorbs the miss so the streak pauses instead of resetting.
A habit tracker you cannot quietly fudge. Every completed day is backed by an image, so a 60-day record means 60 days that happened.
Accountability that costs your partner seconds, not effort. They get the check-in and give a verdict — no chasing, no interrogation.
Stake a token and a missed day is absorbed: the gem stays put and the streak pauses instead of resetting. With no coverage left, the streak starts over — the gem you already cut does not go backwards.
Each staked token covers one missed day, week or month — and makes every approved check-in count for more. Unused coverage returns to your wallet when you finish the goal.
No 21-day rules. What the research says about habit formation, and what to do with it.
The 21-day rule came from a plastic surgeon's memoir, not a study. Here is what the actual research found, and why the range matters more than the average.
Seven steps that survive contact with a bad week — sized correctly, cued reliably, and built to recover instead of collapse.
A partner who says 'nice job' every week is not accountability. What actually changes behaviour is a specific claim, verified by someone who will call it.
The hardest part of a new habit is remembering it. Stacking borrows the reliability of a routine you already have — if you pick the anchor correctly.
The miss rarely kills the habit. What kills it is the story you tell yourself afterward, and the fact that you never planned for a day you would fail.
