The habit loop is free forever — the daily close, calendar, forgiving streak, momentum, and your recent history. Pro unlocks all AI (weekly and monthly recaps, trends, and the brag-doc) plus unlimited history: 29.99/year∗∗,ora∗∗29.99/year**, or a **59.99 one-time lifetime unlock. A 7-day trial lets you try the full AI layer first.
Closing the day with a non-empty entry. That’s it. Proofday never judges the length or quality of what you wrote — showing up and logging honestly is the whole win.
Not necessarily. You can redeem a missed day within a short grace window so it still counts, and your momentum score never crashes to zero over a single miss. You can also pre-declare rest days that protect the streak on purpose.
No. Proofday is goal-free — there are no objectives, OKRs, or tags to maintain. The AI infers your trends and themes from what you actually wrote.
Yes. Proofday is offline-first: you can close a day with no connection, and it syncs across your devices the next time you’re online.
Your journal is tied to your account and is never shared, sold, or used for ads. It isn’t end-to-end encrypted, because syncing and the AI proof layer need to read your entries — see Privacy for the full picture.
iOS, Android, and the web — all from one account, with your journal synced between them. There’s no desktop app.
The app still works fully — you just close the day whenever you open it. The evening nudge is a convenience, not a requirement.
