Kotsumi: Daily Habit Stamps
Build habits. Break habits.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Habits to build, habits to break — one app. Stamp your day in one tap. Miss a day? Nothing resets. Free to start, one-time unlock, no subscriptions, no ads.
"Keep going, gently."
Kotsumi is a simple habit app that turns your daily progress into stamps — one tap, no fuss.
For habits you want to build, and habits you want to break.
Drink water, take a walk, read a book — habits you're growing.
Quit smoking, cut back on snacks — habits you're letting go of.
Kotsumi handles both, gently, in the same app.
■ One tap, one stamp
No complicated setup. Pick a habit, do it, tap to stamp it. That's it.
■ Miss a day? Nothing resets
Most habit apps reset your streak to zero the moment you miss a day. Kotsumi doesn't. Skip a day, and your stamps are still there. Pick up again today — no guilt, no starting over.
■ Gentle with habits you're breaking, too
Trying to quit something? Kotsumi won't shame you for a day you slipped. You can log it honestly, without judgment.
■ Track numbers, too
Habits like "drink 2,000ml of water" or "coffee, max 3 cups a day" are supported with quantity tracking — Kotsumi automatically checks whether you've hit your goal or stayed under your limit.
■ Look back at a glance
A monthly stamp calendar shows your progress at a glance. Check your total stamps and completion rate anytime.
■ iPhone, iPad, and Apple Watch
Log a habit from a widget or your Apple Watch in one tap. On iPad, see your list and details side by side on a roomier screen. Everything syncs automatically across your devices via iCloud.
■ Privacy first
Your data stays on your device and in your own iCloud — Kotsumi doesn't collect behavioral data for advertising.
■ Pay once. No subscription.
Try it for free. If you want everything, unlock it with a single one-time payment — no monthly fees, ever. No ads, either.
You don't need to complete every day.
Just one thing, today. Give Kotsumi a try.
