MyCircadianClock

MyCircadianClock was created by Professor Satchin Panda and his research team at the Salk Institute to expand circadian biology research globally. The app empowers users to log food intake (via optional food photos), sleep patterns, physical activity (including step counts synced from Google Fit or Apple Health), water consumption, medication/supplement timings, and vital health data like blood pressure or glucose levels. This comprehensive log helps researchers understand how when we eat, move, sleep, or hydrate affects health outcomes and longevity.

Participants begin with a two-week baseline logging phase, followed by up to 12 weeks during which they can set personalized goals tied to time-restricted eating, sleep windows, and lifestyle targets. The app also includes reminders, in-app blogs explaining circadian science, and optional meditation tracking. After baseline, users gain access to summarized personal reports that reveal behavioral patterns and support self-optimization.

Importantly, MyCircadianClock is not commercially available without an activation code issued by the Panda Lab—it functions primarily as a scientific tool rather than a consumer wellness app. Data provided by participants helps accelerate real-world understanding of how behavioral timing impacts metabolic health, diabetes risk, inflammation, and more. Prior findings include revelations that many adults have eating windows of 15 hours or longer, highlighting the value of more consistent meal timing.

Ideal for biohackers, longevity advocates, and those curious about circadian balance, the app bridges personal insight and open-source research through data-backed logging—making it a unique tool in the pursuit of optimized, rhythm-aligned health.
