About
UKABU is a quiet notebook for gently lightening your mind.
Toss a passing thought and it drifts onto the screen.
Tap to read it; swipe up to let it go.
Released notes don't vanish — search, and you can always reel them back.
Don't hold it all. But nothing is truly lost.
That's the quiet comfort of UKABU.
— 12 lenses, 12 inner landscapes —
Lotus, Sakura, Ink, Mountains, Pond, Ripple, and the night-sky "Stars."
Choose the scenery by mood. A thought you let go rises as a shooting star,
and tilting your phone lets you look up into the depth of the sky.
— Reel it back —
Find past notes by text, place, or time.
◎ No ads
◎ Notes stay on your device (yours alone)
◎ 11 languages (English, Japanese, Chinese, Spanish, Portuguese, French, German, Korean, Hindi, Indonesian, Arabic)
PRO (one-time purchase)
• 3 extra lenses (Lantern, Pond, Ripple)
• Flow styles (sink / rise / swirl) & auto-play
Toss it, reel it back, take it out.
Float today's small thoughts here for a while.
