What is Body Insights?
Body Insights is a health, recovery, and pacing application designed for iPhone and Apple Watch users whose energy levels vary from day to day. Instead of simply displaying raw charts, rings, and numbers, the platform acts as a plain-language translator for Apple Health signals—including heart rate variability (HRV), resting heart rate, sleep stages, stress, recovery, and optional overnight continuous glucose monitor (CGM) data. By analyzing these metrics, the tool helps users understand their available daily energy and decide whether to rest, take on light or moderate tasks, or push forward, making it helpful for fitness tracking as well as managing chronic conditions like ME/CFS, Long COVID, POTS, fibromyalgia, perimenopause, and post-viral recovery.
Built with a strict focus on user privacy, Body Insights processes and stores all health metrics directly on the user's device. The application requires no user account, never sells personal information to third parties, and gives individuals complete control over what they choose to share. Alongside its core readiness, sleep analysis, energy tracking, and daily coaching modules, the tool features a browser-based fitness age calculator that estimates biological fitness age using Apple Watch Cardio Fitness values.
Features
- Morning Readiness Check: Evaluates morning recovery by reading both HRV and overnight glucose to determine what the body can handle for the day.
- Sleep Analysis: Tracks sleep beyond hours-in-bed by analyzing sleep stages, efficiency, and overnight glucose, translating the results into one plain sentence.
- Energy Tracking Module: Monitors daily available energy specifically tailored for fluctuating bodies, including those experiencing ME/CFS, Long COVID, perimenopause, and post-viral recovery.
- Daily Pacing Coach: Provides plain-language daily pacing recommendations—categorized into Rest, Light, Moderate, or Push—to help users avoid flares and recovery crashes.
- Fitness Age Calculator: Estimates biological fitness age directly in the browser using Apple Watch Cardio Fitness values without storing entries externally.
- Private On-Device Architecture: Operates entirely on-device with no account required and zero data sold to third parties.
Use Cases
- Translating raw Apple Watch and Apple Health data into plain-language daily energy and recovery advice.
- Pacing daily activities for chronic illnesses and variable energy conditions such as ME/CFS, Long COVID, POTS, and fibromyalgia to prevent post-exertional crashes.
- Evaluating overnight sleep quality, sleep efficiency, and glucose stability in a single readable summary.
- Planning weekly schedules and adjusting daily workloads before low recovery leads to multi-day exhaustion.
- Calculating estimated fitness age from Apple Watch Cardio Fitness metrics to monitor cardiovascular health trends.
