Your biological age matters more than the number on your birthday cake. reThrive transforms data from your devices into science-backed insights about how fast you're aging and exactly what to do about it. PRIVACY FIRST Your biometric data is encrypted and belongs to you. We never sell your information. You control what you share and can delete your data and account anytime. DISCOVER YOUR TRUE AGE Most health apps track steps and calories. reThrive tells you what those metrics actually mean for your longevity. By analyzing four core biomarkers (VO2max, heart rate variability, resting heart rate, and lean body mass), we calculate your True Age: a biological age estimate that reflects your actual health status, not just the years you've been alive. A True Age lower than your chronological age means your body is aging more slowly than average. A higher True Age suggests faster aging. Either way, you'll know exactly where you stand. TRACK YOUR PACE OF AGING True Age shows the destination. Pace of Aging shows the journey. This dynamic metric reveals whether you're slowing down or speeding up the aging process based on recent changes in your biomarkers. A Pace of Aging below 1.0x means you're actively reversing biological aging. Above 1.0x means you're aging faster than average. Weekly updates keep you informed. Daily actions keep you improving. ACTIONABLE THRIVE LEVERS reThrive doesn't just measure your health. It shows you which specific actions will improve your biological age most effectively. Our Thrive Levers break down into three daily controllables: • Movement: Optimize your activity and cardiovascular fitness • Performance: Build strength and maintain lean muscle mass • Recovery: Improve sleep quality and manage stress through HRV Each lever connects directly to your biomarkers, so you always know which actions matter most for your goals. WORKS WITH YOUR DEVICES reThrive integrates seamlessly with the wearables and health platforms you already use: • Apple Watch and Apple Health Upcoming: • Garmin • Oura • Fitbit • Polar • And more Your data stays in sync automatically. No manual entry required. SCIENCE-BACKED METHODOLOGY Our True Age algorithm is built on peer-reviewed longevity research linking cardiovascular fitness, autonomic nervous system health, body composition, and all-cause mortality risk. We translate complex science into clear numbers you can act on. Every calculation is transparent. Every recommendation is evidence-based. Every update brings you closer to your healthspan goals. WHO IS THIS FOR? reThrive is built for people who: • Want to optimize healthspan and longevity, not just track workouts • Own wearables but feel overwhelmed by disconnected data • Are looking for an alternative to expensive subscription-based fitness platforms • Believe that understanding biological age is more valuable than counting steps • Want science-backed insights, not generic fitness advice Whether you're an athlete optimizing performance, a health enthusiast exploring longevity science, or simply someone who wants to age well, reThrive gives you the metrics and actions that actually matter.

There's also no support email or contact form so this is the only way to provide feedback. **Developer response:** Thanks for the feedback and for giving us a shot. We’re sorry about the sign-in error, that was on us. We had a brief database issue that prevented new accounts from being created, but it is now fixed. Please give it another try. Also, you were right about the missing contact option. We’re adding a support form directly to the login page in our next release, thanks to your suggestion.
