About this app

One-Line Journal is a daily journal and diary for gratitude, reflection and life's little moments. Start with a gentle prompt, write a short response, and build a journaling habit one line at a time.

FIND YOUR STARTING POINT
Explore seven daily categories: Reflection, Gratitude, Emotion, Growth, Observation, Connection and Insight. Each category has three prompt options. Try another question if one doesn't fit. Answer the categories that speak to you and leave the rest for another time.

KEEP THE LITTLE THINGS
Return to your saved entries in History and revisit the moments, feelings and lessons you recorded. Delete an entry when you choose.

SEE YOUR HABIT GROW
Follow your current streak, best streak, days started and days completed. Browse a monthly activity calendar to see the days you showed up.

MAKE ROOM FOR REFLECTION
Choose a daily reminder, more nudges with a morning preview, or turn reminders off. Set the once-daily reminder time and choose whether to receive a weekly recap in Settings.

SHARE ENCOURAGEMENT
Weekly leagues recognize your writing activity. Standings show your public name and activity statistics, including points and active days. Your prompts and journal text are not displayed in standings.

An account and an internet connection are required to save entries. The app interface and prompts are in English.

Start with one thought, one moment, or something you are grateful for. One honest line is enough.
Daily journal & diary with gratitude prompts. Build a habit, one line at a time.

Version 1.5.1 adds optional app lock and journal export, including this device's drafts, as text or JSON.
