Tiny habits, kept daily — without the guilt

HabitInk today screen — a list of today’s habits with the current streak

Habits aren’t built by how much you do. They’re built by not stopping.

Most resolutions are sized for your best day — an hour at the gym, thirty pages a night. So the first tired evening becomes guilt, and guilt becomes quitting. HabitInk asks the opposite question: what can you keep on a bad day? That becomes the baseline.

Four principles

Behavioral science, translated into a small app you want to open every day.

The 2-minute rule — start tiny

Not “30 books a year” but “read one page.” Learn to show up first. When you create a habit, the smallest version is always the first suggestion.

Read 1 page1-min stretch1 squat

Remember by cue, not by clock

Instead of an exact time, chain things you already do: “wake up → grab a cup → pour water.” The existing action becomes the reminder.

Never miss twice

Missing once is a slip. A missed day shows as a “rest day,” never a red X — and your best run and total days stay beside it, so you come back tomorrow.

Open the app and within seconds you see “Today 3/4” and “Day 16 and counting.” No hours, ranks, or points — today’s small habits are the whole screen.

FAQ

Is it really free?

Yes. Every feature is free with no purchases or subscriptions. A single small banner ad keeps the lights on.

What happens when I miss a day?

It shows as a “rest day,” with no warning color. Your best run and total days stay next to your current streak, so one slip never becomes a failure mark.

Where is my data stored?

Only in your device’s local storage. Nothing is sent anywhere. Uninstalling the app deletes the data with it.

Are reminders mandatory?

No. They are off by default. You can turn on one gentle daily reminder per habit, at a time you choose.

Which languages are supported?

Korean, English and Japanese.
