## What is Cairn?

Cairn is a calm habit tracker built on one image: the small stone towers that mark mountain trails.

Every habit is a trail you are walking. Every time you do the thing, you stack a stone, and today's cairn grows. Count habits, like drink water eight times or do three sets, grow the cairn stone by stone. Your history becomes a trail of small cairns receding into the distance.

Missed a day? It is just flat ground. There is no guilt grid and no broken chain to punish you. The trail simply continues.

WHAT YOU CAN TRACK
- Once-a-day trails that take a single stone.
- Counted trails that grow stone by stone toward a daily target.
- Keep-clear trails for something you want to stop: log only a slip, never a failure, and keep walking.

THE CLIMB
Every stone you stack lifts you ten metres up a real mountain. Summits are climbed in order, from Floyen to Everest, and each one you reach earns a dated passport stamp. It is a quiet long game that turns everyday consistency into a genuine expedition.

COMPANIONS
Share your six-letter trail code with a friend and become companions on the trail. See each other's cairns rise through the day and toss a pebble when someone could use a nudge. Companions are entirely optional. Cairn works fully offline, and no habit names, schedules, or history ever leave your device.

WIDGETS
Keep today's cairn on your home screen. Stack a stone straight from the widget without opening the app, or pin a single trail to a large one-tap counter.

DESIGNED TO BE CALM
- A warm, quiet interface with light and dark themes.
- Gentle haptics and small celebrations when a trail crosses a milestone.
- Local reminders, set per trail, with no accounts required to begin.
- A shareable JSON backup you can export and restore at any time.

Cairn is about steady, forgiving progress. Stack a stone, mark the trail, and let the days add up.
