Most people structure their days around work schedules and social obligations, ignoring the biological rhythms that dictate when their bodies and minds perform best. ARC addresses this disconnect by offering a circadian-based scheduling system that aligns daily activities with individual biological patterns rather than conventional time blocks.
The application begins with a 15-point precision diagnosis that classifies users into four chronotypes: Lion, Bear, Wolf, or Dolphin. This medical-grade assessment identifies unique circadian patterns and generates age-aware protocols that account for how internal clocks shift throughout different life stages. Users receive a perfect day preview displaying their optimized schedule before committing to a subscription, ensuring the recommendations align with their specific goals for focus, sleep, or overall health.
Central to ARC’s functionality is Daily Trajectory mapping, which visualizes energy states across Peak, Dip, and Recovery phases. The system eliminates the notorious afternoon crash by scheduling cognitively demanding work during natural focus peaks and assigning administrative tasks to energy dips. A real-time Circadian Compass provides moment-to-moment guidance, enabling users to make decisions based on current biological readiness rather than arbitrary timeframes.
The platform extends beyond energy management to enhance multiple physiological processes. Photon latency nudges alert users to morning sunlight windows that calibrate internal clocks, while digital sunset tracking determines individual sensitivity to blue light. Night shift logic accommodates professionals with inverted schedules, and seasonal sleep adjustments correlate rest duration with natural light cycles throughout the year. The system integrates 90-minute sleep cycle tracking to optimize wake times that align with natural transitions between sleep stages. The app’s protocols draw from Dr. Andrew Huberman and Matthew Walker’s research, establishing its foundation in circadian science.
ARC also addresses substance timing through caffeine half-life tracking and cutoff warnings that protect sleep quality while maximizing daytime focus. Intermittent fasting window optimization aligns eating periods with metabolic readiness, scheduling meals when digestive function peaks. Movement window identification determines prime exercise timing based on circadian phase and physical preparedness. The app also offers automated reminders and summaries to help users stay on track with their schedules and follow-ups meeting productivity.
