Acorn Jar

Every little treasure, in one jar.

Photograph a print, a postcard, a sticker, or a tiny figure from a museum shop. Acorn Jar lifts the object out with a clean white sticker edge, or finds the corners of a card and straightens it — all on your iPhone, in seconds, even offline.

Every piece drops into an endless glass jar that grows with your collection. Stickers get a jar of their own; paintings and prints fall into a waterfall; postcards stack up and flip over; collections become little boxes you can open.

Add the author with their Instagram or website, tag pieces, and group them into collections. Send your cut-outs to WhatsApp as a sticker pack, put a piece of the day on your Home Screen, or make a wallpaper. No account, nothing uploaded — your jar stays on your phone.
