Get Started FreeWhat is Circadia?
Circadia is not just another mood tracker. It's a comprehensive mental health management tool built from the ground up for people living with bipolar disorder.
Unlike generic wellness apps that treat all moods the same, Circadia understands the unique rhythms of bipolar disorder—the episode states, the warning signs, and most importantly, the critical role of sleep in predicting and managing mood shifts.

Privacy & Security
Your mental health data is deeply personal. Circadia is built on a zero-knowledge architecture, meaning your data is encrypted on your device before it ever leaves—we literally cannot read your information.
Zero-Knowledge Encryption
Your data is encrypted client-side with keys derived from your password. The server never sees plaintext data.
We Can't Read Your Data
Even if compelled by law, we cannot access your data. Only you hold the keys to decrypt your information.
Local-First Design
Full offline functionality. Your data lives on your device first, syncing only when you choose.
No Ads, No Selling Data
Subscription-supported, not surveillance-supported. We make money from the product, not from selling you.
Biometric Protection
FaceID and TouchID support with automatic app locking. Your data stays protected even if your device is compromised.
Screenshot Prevention
Sensitive screens are protected from screenshots and screen recording, keeping your data private.
Sleep-Centric Philosophy
Research consistently shows that sleep disruption is one of the strongest predictors of mood episodes in bipolar disorder. Circadia treats sleep as a first-class citizen, not an afterthought.
How Circadia Uses Sleep Differently
- Baseline Comparison: We don't just track hours—we compare your sleep to YOUR baseline, identifying deviations that matter.
- Critical Thresholds: Automatic alerts when sleep falls below 5 hours (mania risk) or exceeds 9 hours (depression risk).
- Circadian Tracking: Monitor sleep/wake consistency to identify rhythm disruptions before they trigger episodes.
- Predictive Insights: Correlate sleep patterns with mood data to identify your personal warning signs.
