## What is Circadia?

Fasting, without pressure.

Circadia is a private fasting timer, journal, and educational wellness companion built around your routine. Choose a familiar rhythm or a custom goal from 1 to 24 hours, then adjust, pause, or end whenever you need.

FLEXIBLE TIMER
- Timed plans and custom goals from 1 to 24 hours
- Elapsed and remaining-time views
- Pause, resume, edit, or end without losing context
- Open Fast mode with a clear safety confirmation and no finish alert
- Widgets and Live Activities for glanceable progress

PRIVATE WELLNESS JOURNAL
- Log completed fasts, hydration, mood, notes, and weight
- Review patterns, trends, streaks, and milestones
- Honest logging earns recognition; longer fasts do not earn extra rewards
- Export your records on supported Apple devices

EDUCATIONAL COACH
- Ask about meals, hydration, sleep, travel, exercise, and your current timer
- Built-in guidance works without an account
- An optional downloadable model can select among reviewed presentation styles on your device
- Clear boundaries prevent diagnosis, treatment, medication, or dosage advice

ON YOUR WRIST
Use Circadia on Apple Watch and Wear OS for quick timer controls, hydration logging, and progress at a glance.

PRIVATE BY DESIGN
Your fasting records and coach prompts stay in app-private storage. Circadia has no account, advertising, behavioral tracking, or third-party analytics.

Do not fast if you are pregnant or breastfeeding, have a history of disordered eating, or have been advised not to fast.
