One daily win

A single entry per day. Write the one thing that mattered. Entries lock after 24 hours — no editing the past, only today.

Private lists

Todos, ideas, recurring items — kept in one place, away from the noise. No sharing, no collaboration, no notifications from others.

Widget and Apple Watch

Log your win from your lock screen or your wrist. A complication on your watch face shows the streak and prompts you at the end of the day.

iCloud Drive sync

One file — Daybook.daybook — in your iCloud Documents folder. Open SQLite format. Readable, portable, entirely yours.

Dark mode only

Daybook is built for the way you actually use your phone — at night, in quiet moments, in the small space between the day's end and sleep.

Your daybook, forever

The free tier keeps the last 7 days. Paid unlocks unlimited history — $2.99/month, $19.99/year, or $59.99 once. No subscription required to own your past.

Your data. One file. Yours forever.

Daybook stores your entries in a single Daybook.daybook file in your iCloud Documents folder — standard SQLite, open format, readable by any database tool. No Daybook servers. No accounts. No analytics. No surveillance of how you spent your day. Built in Pune, India.

Common questions

What counts as a 'win'?+

Whatever mattered most that day to you. One thing you did, completed, realised, or felt. There is no right answer — the practice is the point. Write it in a line, lock it in, and move on.

Why can't I edit yesterday's entry?+

Entries lock after 24 hours by design. Daybook is a record of how the day actually felt, not a polished version written later. The constraint is the feature.

Where is my data stored?+

Daybook stores everything in a single file called Daybook.daybook in your iCloud Documents folder. It's standard SQLite — you can open, back up, move, or delete it at any time. No Daybook servers, no accounts, no analytics.
