Overview
Kkumi is an on-device editor for four-cut photos, seamless social carousels, and digital scrapbooking. Pick a template, add your photos, then layer stickers and backgrounds until it feels completely yours. Korean and Japanese typography are first-class — line breaking, letter spacing, and vertical writing all work the way they should.
Everything runs locally on your iPhone. There is no account, no advertising, and no server upload — your photos and edits never leave the device.
Key Features
52 ready-to-use templates

Scrapbook, keyring, people, objects, food, and travel stickers — unique subjects, not color-swapped duplicates. Plus 16 shapes with a 10-color palette.
66 photographic backgrounds
Cafe, room, city, nature, travel, and mood collections. Tap to replace the page background; it stays naturally behind your photos and stickers.

Word-level line breaking, letter and line spacing controls, and curated handwriting typefaces. Vertical writing for Japanese is supported too.
On-device subject cutout
Remove a photo's background in one tap, right on the device — no server round-trip, no waiting.
