Habit Stamp Card

Habit Stamp Card is a simple stamp card for building habits, inspired by Japan's summer exercise stamp cards. Make a card for something you want to do, and double-tap a date to add a stamp. Choose a stamp design and color for each card, see your month at a glance, and add or remove stamps for past days. No ads, no sign-up. Your data stays on your device, and you can export a backup file. Light and dark mode. Available in Japanese and English.
