BioClock

BioClock is a calm, privacy-first wellbeing app designed to help you understand your daily rhythm. It estimates your BioTime, Circadian Regulation Score (CRS), circadian phase, predicted sleep window, mood pattern, rhythm stability, and trend shifts over time. The app is built for reflection and self-awareness, with local-first processing and offline use at its core. BioClock can bring together information from optional sources such as manual input, Health Connect, device sensors, and future connected rhythm services. You stay in control of which sources are enabled. Core features work even without any online account. With BioClock you can: • View live BioTime alongside standard time • See rhythm alignment, sleep pressure, mood estimate, and data quality • Track 7-day and 30-day trends in sleep, timing, light, activity, and mood • Receive gentle reminders for focus, wind-down, rest, and bedtime • Set alarms based on standard time or a BioTime-informed wake window • Export local CSV, JSON, wellbeing summaries, and clinician-support summaries • Use the app in multiple languages, including English, Czech, Hungarian, and Spanish BioClock is designed with a calm visual style and a non-clinical tone. It does not present itself as a diagnostic device, psychiatric evaluator, or medical judgement tool. All scores, mood outputs, rhythm insights, and summaries are informational estimates only. Privacy comes first: • Local-first storage and processing • Offline core functionality • Optional data sources and sync • No ads • No selling of personal data • User-controlled exports and deletion Some features may request optional access to Health Connect, activity data, light sensing, notifications, or alarm-related permissions so the app can provide more useful rhythm estimates and reminders. These are used only for the enabled features. BioClock is suitable for people who want a gentler, more understandable view of sleep timing, rhythm consistency, mood-energy patterns, and daily wellbeing signals without overstating certainty. Important: BioClock is not intended to diagnose, treat, cure, or prevent any disease, and it is not a substitute for professional medical advice.
