Know your real age. Gradual calculates your biological age from five health dimensions, then gives you the tools to change it. Labs, vitals, workouts — all in one place.
Gradual calculates your biological age from five science-backed health dimensions then gives you the tools to improve it. Biomarkers, vitals, workouts, and longevity insights, all in one place.
YOUR BIOLOGICAL AGE (GRADUAL AGE)
See beyond the calendar. Your Gradual Age is a composite biological age built from five pillars: cardiorespiratory fitness, autonomic health, sleep quality, vascular function, and PhenoAge blood biomarkers. Compare each dimension to your chronological age, track your trend over time, and share your results with your doctor.
DAILY READINESS SCORE
Know when to push and when to recover. Your Readiness Score combines HRV, resting heart rate, sleep, training strain, and mood — calibrated to your personal baselines, not population averages.
AI-POWERED LAB ANALYTICS
Upload a PDF from any lab provider and Gradual extracts the results automatically. Track 40+ blood biomarkers across cholesterol, glucose, hormones, vitamins, inflammation, and more. Every optimal range is backed by peer-reviewed citations so you can take control of your healthspan.
HABITS THAT COMPOUND
Small inputs, big outcomes. Build daily routines around supplements, fitness goals, mindfulness, and sleep targets. Track streaks and monitor weekly consistency with zero friction and no manual entry.
CONNECT YOUR DEVICES
Sync with Apple Health and Strava. Sleep, HRV, resting heart rate, VO2 max, training load, and more flow in automatically — no extra wearable required.
AI HEALTH INSIGHTS
Get context-aware analysis across your habits, vitals, and labs. Tap any insight to ask follow-up questions. Understand what's driving your biological age and what you can do to reverse aging trends. Rule-based insights are always free.
TRAINING LOAD & FITNESS TRACKING
Track weekly volume across running, cycling, and strength training. See your chronic load trend and get recovery recommendations based on your current state.
STRENGTH TRAINING
Log every rep and set with a purpose-built workout tracker. Drag to reorder exercises, track progressive overload, and review your session history. Start from templates or build your own.
HEALTH NEWS
Stay informed with curated articles from PubMed, NIH, and Harvard Health, filtered for longevity, anti-aging research, and wellness topics that matter to you.

I'm 38 and got into the whole longevity thing after my dad had a health scare last year. Tried a few apps but they were either way too intense or way too basic. Gradual hit the sweet spot where it nudges me to do better without making me feel bad about myself. I've been way more consistent with my walks, sleep, and water intake than I was all of last year.
Finally a health app that actually measures aging, not just steps
stan_yu
Most health apps just count calories or steps. This one tells you your biological age and shows you exactly how to improve it. The lab upload feature is a game changer – no more manually typing in blood test results. And the readiness score actually helps me decide if I should hit the gym or rest. Solid.
Good for health insights
The Zenix
This has become a part of my routine for monitoring wellness trends. It interprets health data into actionable longevity insights which has been helpful. It feels like it was built for people who want a more scientific approach for health tracking vs. Athlytic that I used previously. Definitely worth a look if you’re into data-driven health optimization.
Rigorous
Finallyreadyfortheexam
Great app for building consistent health habits and has lots of interesting data points. I appreciate that they update it to keep making it better.
Your strength training history is now complete. Workouts recorded in Apple Health or any other fitness app appear alongside sessions you log directly in Gradual.
