About this app

Diary, journal, memo, habit log — all in 1 second.

OneTapLog is the 1-second diary app that strips away the friction of writing.

Like a chat app, you write to yourself in a message-style flow.
The keyboard pops up the moment you open the app — tap send and your log is saved with a timestamp. Tags organize habits and feelings naturally, and the calendar and Gantt chart let you look back anytime.

===== What OneTapLog can do =====

1. Write in 1 second
Ready to type the moment the app opens. No extra screens.
The chat-style flow lets you capture thoughts the instant they hit.

2. Look back through your timeline
Every log lined up chronologically. Just scroll to meet your past self.
Date headers make it obvious what you wrote and when.

3. Organize with #tags
Type #tag in your text and it's auto-detected.
Search and filter by tag to revisit a specific theme.

4. Calendar at a glance
A monthly calendar shows the days you've logged. Tap a date to jump to that day.
Tags per day let you see what you were up to in one look.

5. Visualize habits with a Gantt chart
Each tag becomes a row on a Gantt chart.
See your streaks for workouts, reading, work, and more at a glance.
