Description

Abakusapp is a hands-on soroban (Japanese abacus) number-entry toy for Pebble's touch-capable watches (Pebble Time 2, Pebble Round 2). Five vertical stacks let you dial in any 5-digit number: swipe a bead towards the separator bar to activate it -- and everything between it and the bar -- or swipe away to deactivate; tap for a quick +/-1. A long horizontal swipe clears everything. Works with buttons too, on every Pebble: Select picks a stack, Up/Down adjusts it, long-press Select clears. The current number is always echoed as plain digits below the stacks. Stone/background/separator colors are configurable from the phone's Settings screen. This is an experimental first project built specifically to learn Pebble's new touch/gesture API. It's done with the skill (see https://repebble.com/blog/spring-2026-pebble-app-contest) using Claude.
