About Shrimpodoro: Pomodoro Timer
Shrimpodoro is a pomodoro timer with one rule: your next round stays locked until you squat. Focus for 5 to 120 minutes while a tiny hand-drawn version of you slowly curls into a shrimp. When time’s up, do 5, 10 or 20 squats, counted by the front camera on your iPhone (the video is never recorded or uploaded), and a tomato drops into your pile. Every squat also climbs a meter toward landmarks from a little house to Everest.
Version 1.1.0 announces iPhone Duo support. Half-folded, the live squat count sits above the fold and your climbing progress below, and the pages are adapted for the open inner screen.
