Cairn is a calm, private place to track your sobriety and celebrate each day forward. It's a support tool for your own journey — not treatment, and not a substitute for professional help.
Free, forever:
- Sober day counter that keeps going as long as you do
- One-tap daily check-in
- Milestones and gentle celebrations as you climb
- Stats: days sober, money saved, and a calendar of your journey
- Private mood and craving journaling
Reflection (optional upgrade):
- Gentle, non-clinical observations about patterns in your moods and cravings
- A weekly reflective summary
- Unlimited journal history
Private by design:
Your streak, check-ins, stats and journal stay on your device. Nothing is sold or shared. Only the reflection entries you choose are sent securely for processing.
If you are in crisis, Cairn includes crisis resources — and always encourages reaching out to professional help.
