Cairn: Gentle Habit Tracker

Cairn is a calm habit tracker built on one image: the small stone towers that mark mountain trails. Every habit is a trail. Each time you do it, you stack a stone and today's cairn grows. Counted habits, like eight glasses of water or three sets, grow stone by stone toward a daily target. Your history becomes a line of small cairns along the trail. Missed a day? It is flat ground. There is no broken chain to punish you. The trail continues. WHAT YOU CAN TRACK - Once-a-day trails that take a single stone. - Counted trails that grow toward a daily target. - Keep-clear trails for something you want to stop. You log a slip, not a failure, and keep walking. THE CLIMB Every stone you stack lifts you ten metres up a real mountain. Summits come in order, from Fløyen to Mount Everest, and each one you reach earns a dated passport stamp. COMPANIONS (OPTIONAL) Share your six-character trail code with a friend to walk together. You see each other's daily progress and can toss a pebble, with a short note if you like, when someone could use a nudge. Companions use an anonymous account and the display name you choose. Habit names, schedules and history stay on your phone. You can delete your Companion cloud data at any time from Data & privacy, and your local trails stay.
