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.
