LogBook: Habit Tracker & Diary

LogBook is a habit tracker with a journal attached. Tick the habits you kept, then write the day down. Months later the streak tells you what you did — and the journal page tells you why.

Most tracker apps give you a number and nothing to look back on. LogBook is built so the looking back is the point.

ONE DAILY CHECK-IN
At a time you choose, LogBook asks about your day. Tick the habits you kept, add a photo, write a line or a page. Two minutes, once a day. That daily check-in is the whole ritual.

A STREAK YOU CAN SEE
Tally marks, not a badge. Every habit keeps a streak grid of its own — a habit calendar you can read a month or a year at a glance. Tap any day in the month view to fix one you forgot to tick.

A JOURNAL YOU CAN REREAD
Every check-in becomes a dated page in your log. Scroll back through the daily journal — a diary of the days you kept — like a notebook, with the photo and the ticks still attached to the day.

HABITS TO BUILD, HABITS TO QUIT
Track the run you want to start and the scroll you want to stop, side by side in one app.

HOME-SCREEN WIDGET
Your habit grid on the home screen. See the streak without opening the app.

SHARE THE DAY, OR DON'T
Post a day to a small feed of people you trust, and react to theirs. A quiet accountability circle with your friends — off by default, nothing public, no follower count.

WORKS OFFLINE
Every check-in is written on the phone first and synced when there is a signal. An offline habit diary and daily log that still works on a plane, on the tube, or in a cabin.

DARK MODE
Designed, not inverted. The same paper, dimmed.

WHAT LOGBOOK WON'T DO
No guilt notifications. No leaderboard, no points, no streak insurance to buy. Miss a day and the ledger just says so — tick it late if you actually did it.

THE FREE LOGBOOK
Three habits, kept forever, with the full daily check-in, the full journal, the widget and the feed.
