Hold today's heart, gently.

Pogeun is a warm, private mood-tracking diary. On a calendar, you place each day's feeling with a single companion character named Pori — and a whole month blooms into one beautiful 'heart sunset' gradient. No growth or productivity pressure, just the gentle comfort of 'were you okay today?'

The feeling

Warm, cozy, and tender — cream, peach, and sunset colors with soft shadows, a handwritten touch, and a kind, gentle tone. Like a starry night and a dream.
