FAQs

How does Peaks analyze my energy peaks and dips?

Peaks uses your existing sleep data and applies the two-process model of sleep regulation, combining your circadian rhythm with sleep pressure. This scientific framework, also used in aviation and shift-work research, allows the app to predict your optimal windows for focus, fatigue, and recovery.

Is my health data safe and private with Peaks?

Yes, Peaks is designed with privacy at its core. Your health data never leaves your iPhone. There are no sign-ups, no servers, and no third parties involved. The app works entirely offline, ensuring your personal information remains on your device.

How is Peaks different from other sleep tracking apps?

While many apps track sleep, Peaks goes further by interpreting that data to provide actionable insights into your circadian rhythm. It helps you plan your day around your body's natural energy fluctuations, suggesting optimal times for deep work, exercise, and rest, rather than just reporting sleep metrics.

How long does it take for Peaks to provide accurate predictions?

Peaks starts working immediately by connecting to your existing sleep data. The accuracy of its predictions improves over time as it learns more about your individual sleep patterns and how they influence your daily energy fluctuations. It updates daily based on how you actually slept.

Does Peaks offer any features for travel or shifting schedules?

Peaks is developing features to help with travel and shifting schedules. Upcoming functionality includes personalized guidance to shift your rhythm when crossing time zones, helping you combat jet lag and maintain your energy balance.
