Shelfie

Read, swipe, level up. A reading tracker you drive with your thumbs: books are arcade passes you flick through, drag up to turn pages and drop onto shelves. Every move is a spring that keeps your finger's speed.

No ads, no build step. Accounts are optional: without one, everything stays on your own device.
