ぽてまるアプリ

The character's appearance changes daily in sync with your iPhone's step count. On days you walk, the character looks trim and fit; on days you don't walk, it becomes rounder. But since the rounder appearance is designed to be cute, it doesn't feel like you're being criticized. There's no comparison with others—your step count stays entirely within your device.
