Exercise cut cancer recurrence risk by 28% in a landmark trial. This app tracks the exact unit that trial measured: MET-hours. The CHALLENGE Trial followed colon cancer survivors through a structured exercise program. The results, published in the New England Journal of Medicine in 2025: a 28% lower risk of cancer recurrence and a 37% lower risk of death. The trial set its targets in MET-hours, a clinical unit no fitness tracker reports. MET Hours calculates them for you, automatically. AUTOMATIC FROM YOUR APPLE WATCH Approve access once and your workouts log themselves: type, duration, energy, and heart rate. After each workout, a notification shows the MET-hours you earned, your weekly total, and your zone. Prefer manual entry? Every workout can be logged by hand instead. FOUR ZONES, ONE GOAL Your week climbs through Baseline, Active, Shield, and Peak Resilience. The Shield zone (20+ MET-hours) reflects the trial's target range. A clear weekly gauge shows exactly where you stand and what one more walk would do. VISCERAL FAT PROTOCOL (OPTIONAL) Track high-intensity sessions and your time in heart-rate zones 4 and 5, with zones calculated the same way Apple Watch calculates them: from your own resting and maximum heart rate. REPORTS FOR YOUR CARE TEAM Share a clean weekly or multi-week summary with your oncologist, physiotherapist, or family. PRIVATE BY DESIGN No accounts. No analytics. No servers. The app never connects to the internet. Your health data stays on your device, protected by Apple's on-device security. Always free. Built for colorectal cancer survivors. The trial studied a supervised three-year exercise program; this app is an educational tracking tool, not a medical device. Always consult your healthcare professional before beginning or changing an exercise program.
