Every promise you keep to yourself builds trust in yourself. Corekept is a small app for one skill: saying you'll do something, then doing it.

PLAN LIKE A PESSIMIST
A block is a set of promises you keep, and commit to for 1 to 14 days. Then stop and look again: life changes. Once it starts, it locks, even when the day gets hard.

EXECUTE LIKE AN OPTIMIST
• Say it. Choose what you'll do and for how many days. Starting today, each promise can be taken back for 30 minutes. Then it's locked.
• Do it. Mark each one kept, in the app or from the widget. Only you know if you kept it, so honesty is the whole system.
• Own it. Your day stays open until you start the next one. Then you mark what's left, and your lion shows how Trust moved.

SMALL ON PURPOSE
• Trust is one number for how reliably you keep your word, shown as the strength of your lion. We've found that what matters most is the share you keep.
• A nudge at each end of your day, if you want one.
• Extreme mode: Corekept becomes your home screen, with today's promises and only the apps you allow. It adds friction, not a lock, and you can switch back any time.

FREE, THEN ONE PAYMENT
Free stays free: 3 promises a day, 1-day blocks, Trust, your lion and the widget.
The Unlock is one payment, yours for good: as many promises a day as you choose, blocks of up to 14 days, Extreme mode, and new animals as they arrive.
No subscription. No ads, ever.

YOUR PROMISES STAY ON YOUR PHONE
No sign-up and no account. Your promises stay on your phone, and in your own Google backup if that's on. We can't see them. Corekept sends anonymous usage statistics, which never include the text of a promise, and you can turn them off in one tap.
