Cairn · Habit Tracker

Every check-in counts.

A gentle habit tracker for the small things you want to keep doing. No streaks, no guilt — each check-in drops another stone onto your stack, and they add up to growth you can see.

From a small thing to your cairn

A cairn is a stack of stones that marks a path. This one marks yours — and it only grows.

1

Pick something small

“Read 10 minutes.” “Drink water.” “Stretch.” Anything you want to keep doing — a few taps, no setup.

2

Check in when you do it

One gentle tap. A stone falls onto your stack, the counter goes up, and that’s it — it counted.

3

Watch it accumulate

Days, badges, levels. A pile of small wins that only you built — and that never shrinks.

Built to feel good on quiet days

Most habit apps keep score against you. Cairn keeps score for you.

No streaks. No guilt.

Missed a day? Nothing breaks, nothing resets. Cairn never asks how long you were away — it only counts the times you showed up.

Levels that only rise

Your level is the height of your cairn. Every check-in adds a stone; the stack never gets smaller, and neither does your progress.

Badges along the way

Milestones that honor effort, not perfection. Once a badge is yours, it stays yours.

Insights that stay kind

Heatmaps and totals in one calm color. Busy days glow brighter; quiet days are simply quiet — never red, never marked.

Private by design

No sign-up, no email, no trackers or analytics. Optional cloud backup uses an anonymous account — and your data exports free, anytime.

Follows you to a new phone

Turn on backup and a single recovery code moves your whole history across — no accounts, no passwords, works across iOS and Android.
