Zero-knowledge encryption
Every entry is sealed on your device before it touches storage. We have no key, no copy, no access.
One private app for habits, todos, notes, and the moments in between.
Encrypted on your device with AES-256-GCM + Argon2id.
Even Singletick can't read it. Nobody can.
Everything in one place
Habits, todos, notes, pledges, mood, focus — every feature respects the same privacy charter.
Every entry is sealed on your device before it touches storage. We have no key, no copy, no access.
Encrypted blobs go to your Google Drive or iCloud. Even your cloud provider can’t read them.
See how mood, sleep, and habits move together. On your device. We never see the result.
Commit to a goal with a friendly penalty if you slip — a public admission, a journal entry, a donation hint.
One-tap habit completion from the home screen. Streak count on the lock screen and Dynamic Island.
A separate PIN seals your most personal notes. Auto-locks the moment you switch apps.
Pomodoro sessions tied to a habit, with a Live Activity countdown so you stay in flow.
