BioStat isn't guesswork. It's built on decades of actuarial research.
The gold standard in mortality modeling since 1825. Our implementation uses parameters calibrated from modern demographic data.
Your lifestyle risk factors are integrated using Cox regression, the same method used in medical research studies.
Our baseline parameters are calibrated using World Health Organization 2020 mortality statistics and the Human Mortality Database.
BioStat uses the same actuarial models that insurance companies use to calculate life expectancy. However, it's important to understand that no model can predict an individual's lifespan with certainty. Our predictions are statistical estimates based on population data and your personal health factors. The real value is in tracking how your lifestyle changes affect your predicted longevity over time.
With your permission, BioStat reads: step count, heart rate, resting heart rate, heart rate variability (HRV), VO2 Max, sleep duration and stages, exercise minutes, and basic body measurements. All data stays on your device - we never send your health information to external servers.
Absolutely. Your health data never leaves your device. BioStat processes everything locally on your Apple Watch and iPhone. We don't have servers that store your personal information. If you enable iCloud sync (Pro feature), data is encrypted end-to-end by Apple's iCloud infrastructure.
The free version gives you the core life expectancy countdown with 5 lifestyle risk factors. Pro unlocks 14 risk factors, historical trend charts, watch complications, advanced health insights (HRV, VO2 Max analysis), sleep stage tracking, achievements, goals, and coaching features. Pro is available as a monthly subscription, yearly subscription (40% savings), or lifetime one-time purchase.
Yes, you can cancel anytime through your Apple ID settings. Your Pro features will remain active until the end of your current billing period. If you've purchased the lifetime option, you have permanent access with no recurring charges.
BioStat requires Apple Watch Series 4 or later running watchOS 10.0 or higher. For the companion iOS app, you need iOS 17.0 or later.
