Peaks is a new indie app that uses Apple Health sleep data to help you understand your circadian rhythm and plan your day around your natural energy peaks and valleys.
Managing your energy throughout the day can be a challenge, especially when you're not sure when your natural peaks and valleys occur. A new indie app called Peaks aims to solve this problem by analyzing your sleep data from Apple Health and providing actionable insights about your circadian rhythm.
How Peaks Works
Peaks takes the sleep data that's already being collected by your Apple Watch or other sleep-tracking devices and transforms it into practical advice for your daily routine. The app analyzes patterns in your sleep to determine when your energy levels naturally rise and fall throughout the day.
Once Peaks has enough data, it can tell you exactly when you're likely to be at your most productive, when you should schedule workouts, when to avoid caffeine, and when it's time to start winding down for the evening. The goal is to help you avoid those dreaded energy crashes that can derail your productivity and mood.
Key Features
What makes Peaks particularly useful is its comprehensive approach to sleep and energy management:
- Energy Window Tracking: The app identifies your peak energy periods and suggests optimal times for different activities
- Sleep Insights: Track sleep debt, recovery rates, and sleep quality over time
- Calendar Integration: Sync your energy windows to your calendar for easy planning
- Cross-Device Support: Works with any sleep data that syncs to Apple Health, not just Apple Watch
- Apple Watch App: Quick access to your energy data right on your wrist
- Complications and Widgets: See your energy status at a glance from your watch face or iPhone home screen
Availability and Pricing
Peaks is available for free on the App Store for devices running iOS 18 or watchOS 11 and later. For users who want the full experience, Peaks Pro is available through a subscription:
- $4.99 per month
- $29.99 per year (saving about 50% compared to monthly)
The Pro version unlocks additional features like custom schedules, sleep scores, and calendar integration.
Why It Matters
Understanding your circadian rhythm isn't just about feeling more energetic—it can have real impacts on your health, productivity, and overall well-being. By aligning your activities with your natural energy patterns, you can work more efficiently, exercise more effectively, and potentially improve your sleep quality over time.
For anyone who's ever struggled with afternoon slumps or wondered why some days feel more productive than others, Peaks offers a data-driven approach to understanding and optimizing your daily energy cycles.
