Description

Abakuswatch tells the time (always 24-hour) using the logic of a soroban, the classic Japanese abacus. Four vertical stacks read left to right like a digital clock: tens-of-hours, hours, tens-of-minutes, minutes. Each stack has one "heaven" bead worth 5 above a bright separator bar, and four "earth" beads worth 1 each below it -- only a bead pushed towards the bar counts. Heaven beads slide down to touch the bar from above; earth beads slide up to touch it from below. Read a stack's value by adding 5 (if the heaven bead touches the bar) to however many earth beads are touching it. Stones, background, and the separator bar are all colors you can pick from the phone's Settings screen. Hourly vibration. It's done with the skill (see https://repebble.com/blog/spring-2026-pebble-app-contest) using Claude.
