## What is Cairn?

Cairn is a calm intermittent fasting app built to help you stay consistent without noise, pressure, or clutter.

Track your fasting windows with a simple timer, follow a routine that fits your day, and review your progress in a softer, more mindful experience.

Whether you’re starting with 12:12, easing into 14:10, settling into 16:8, or exploring longer fasting windows over time, Cairn helps make intermittent fasting feel clear and approachable.

What you can do with Cairn
- Track intermittent fasting windows
- Start and end fasts with a simple guided flow
- See elapsed and remaining time during an active fast
- Use common fasting schedules like 12:12, 14:10, 16:8, 18:6, 20:4, and 23:1
- Get reminders and fast completion notifications
- Review fasting progress in a calm visual archive
- Reflect after ending early without judgment
- Keep your fasting history stored locally on your device

Designed for a gentler routine
Cairn is for people who want a clean fasting tracker and timer without turning the experience into a loud optimization tool. It’s minimal, supportive, and built around rhythm, consistency, and follow-through.

Instead of overwhelming charts or aggressive coaching, Cairn focuses on clarity, calm, and daily practice.

A note on approach
Cairn is a fasting tracker and timer. It is not a medical device and does not provide medical advice.
