Your Daily Fitness Score.
Train smarter.
ScoreVitals passively reads your health data and delivers a single daily score so you always know when to push hard and when to recover.
ScoreVitals is a free fitness intelligence app for iOS and Android that reads health data from Apple Watch, Garmin, Polar, Oura, Fitbit, and other wearables to calculate a daily fitness score out of 100, a training readiness recommendation with target heart rate zone and duration, and injury risk alerts — all using peer-reviewed algorithms including TRIMP, ACWR, and VO2max estimation. No new hardware or subscription required.
Works with Apple Watch, Garmin, Polar, Oura, Fitbit, and Samsung Galaxy Watch.
The Score
Your Daily Fitness Score: Four Science-Backed Pillars
One number, four dimensions. Your daily score (0-100) combines research-backed health metrics into a single number you can act on every morning. See how each score is calculated →
Cardio
Tracks training impulse (TRIMP) from every workout — runs, rides, gym sessions — using Banister's heart rate reserve formula to quantify your training load.
40% weightSleep
Analyses sleep stages — light, deep, and REM — along with duration and efficiency to measure how well your body recovered overnight.
30% weightRecovery
Tracks heart rate variability (HRV) and resting heart rate against your personal baselines, so your readiness reflects your unique physiology.
20% weightBody Composition
Monitors weight stability and BMI trends over time. Sudden changes are flagged and factored into your readiness score.
10% weightFeatures
Fitness Tracking Features — No Manual Logging
Everything you need, nothing you don't. ScoreVitals works passively in the background — no manual input, no complicated setup.
Daily Readiness Score
A 0-100 score combining all four pillars into a single number with a personalised training recommendation every morning. See the tiers →
Injury Prevention
Automatic acute-to-chronic workload ratio monitoring warns you before dangerous training spikes cause injuries. Stay in the optimal 0.8–1.3 zone with real-time alerts.
Training Recommendations
Personalised daily guidance that adapts to your readiness — from “Ready to Push” to “Rest & Recover” with intensity targets.
Sleep Analytics
Full sleep stage breakdown — light, deep, and REM — plus duration, efficiency, and quality metrics that feed into your score.
Recovery Tracking
HRV trends, resting heart rate, and recovery metrics compared against your personal baselines to show how your body is adapting.
Smart Notifications
Morning score briefs, post-workout results, evening reminders, and injury risk alerts — all timed to your timezone.
Apple Watch
Real-time complications on your watch face, wrist-based heart rate monitoring, and automatic workout detection — no phone required.
25+ Activity Types
Running, cycling, swimming, HIIT, strength, yoga, rowing, hiking, and more — every session automatically scored and tracked.

Banister's TRIMP [ref]
Training impulse calculated from heart rate reserve and gender-specific coefficients, quantifying internal training load for every session.
EWMA ACWR [ref]
Exponentially weighted acute-to-chronic workload ratio comparing 7-day vs 28-day loads to keep you in the optimal (0.8–1.3) training zone.
ACSM VO2max [ref]
Aerobic capacity estimated using formulas validated by the American College of Sports Medicine, updated weekly as your fitness evolves.
Testimonials
What Athletes Say About ScoreVitals
From marathon runners to daily walkers — real people using ScoreVitals to train smarter and recover better.
The readiness score has completely changed how I plan my training weeks. My ACWR has stayed in the sweet spot since I started, and I genuinely believe it helped me avoid the overtraining injury I got last season. The fact that it pulls everything from Apple Health automatically is what makes it stick.
The Karvonen-based heart rate zones, sleep scoring methodology, and HRV recovery analysis are all grounded in peer-reviewed literature. I have recommended ScoreVitals to several patients.
I am not a data person at all, but ScoreVitals makes it so simple. One number every morning that tells me how I am doing. My sleep score went from the mid-60s to consistently above 80 after two months. The dark design is gorgeous too.
The heart rate recovery tracking after workouts tells me exactly how my cardiovascular fitness is trending. Seeing my fitness age from VO2max is genuinely motivating — apparently I have the cardiovascular system of a 44-year-old.
The training load gauge is my favorite feature. ScoreVitals shows my acute-to-chronic workload ratio with clear zones. When I crept into the caution zone, I dialed back and avoided what would have been another tweaked shoulder.
The scores are based on actual research — they cite the specific studies behind their TRIMP calculations, sleep quality methodology, and heart rate zone formulas. I finally trust a fitness number.
Getting back into exercise after having my daughter has been hard, and I needed something that would meet me where I am. Even when my scores are lower, the app uses encouraging language instead of telling me I am failing.
I train across swimming, cycling, and running, and ScoreVitals handles all of them. Each workout gets its own session score with TRIMP, efficiency percentage, and detailed heart rate zone breakdowns.
The readiness gauge on the home screen is satisfying to look at every morning, and the health feed shows all my workouts, sleep sessions, and vitals in one timeline — way cleaner than bouncing between three different apps.
I do not do intense workouts — I walk every day and try to sleep well. The 7-night sleep averages have helped me identify that I sleep much better on days I walk in the morning. Simple, clean, and actually useful.
