BioClock is a premium-feeling Android app for everyday circadian awareness. It shows BioTime beside standard time, estimates rhythm alignment and sleep timing, gives gentle reminders and alarms, and keeps your wellbeing data local-first and exportable.
Alignment, regularity, light, activity, and timing in one readable score.
Shows state confidence, light confidence, session length, next window, and recovery-sensitive guidance.
History-based and calm, with an optional bedtime reminder.
Standard-time or BioTime-aware alarms with safety rules.
BioClock helps people reflect on timing, sleep regularity, drift, light, activity, and internal rhythm. It is designed to be informative, observational, and supportive. It does not pretend to diagnose or replace care. Instead, it makes rhythm more visible, more understandable, and easier to act on calmly.
Understand BioTime drift, rhythm stability, phase changes, chronotype tendencies, and how regular recent days have been.
Get predicted sleep windows, suggested bedtime, calm reminders, and safer BioTime-aware alarm behavior.
Combine manual input, phone motion, ambient light, Health Connect, and optional CRS platform sync in one normalized model.
