Oneuldo - One Line a Day

One line a day is enough.

Oneuldo is a diary app that keeps each day as one mood emoji and one line (100 characters). Nothing long to write, so it actually continues.

■ Today Pick one of five moods and write a line. Past days can be filled in later.

■ Mood calendar The calendar fills with the color of each day's mood — a whole month at a glance.

■ Monthly recap card Days recorded, most frequent mood, best day, mood distribution and longest streak, rendered as a card you can share as an image.

■ Streak Counts consecutive days. Missing one is never scolded.

■ Reminder and lock One reminder a day at the time you choose. Lock the diary with Face ID or your device passcode.

■ Export Export everything as text or CSV.

■ No account, no server No sign-in. Every entry stays on this device. No ads, no analytics. Korean and English.
