RepRecord brings science-backed workout tracking to your pocket. Every muscle gets an MTQ score derived from effective sets, muscle-specific saturation parameters, and an exponential model grounded in peer-reviewed research. Completely free, completely private.
A fitness app that respects both your progress and your privacy.
Every muscle gets an MTQ score on a 1–10 scale using parts-weighted effective sets (sets × parts / 7) fed into an exponential saturation curve. Per-session and weekly MTQ are always calculated separately.
All your workout data lives exclusively on your device. No account needed, no cloud sync, no analytics. Your data is yours alone.
Visualise your strength progression over time. RepRecord shows you exactly when and how you're improving, or when it's time to push harder.
A visual breakdown of volume per muscle group each week. Instantly spot imbalances and training gaps before they become problems.
Build reusable workouts from the full 327-exercise library, distribute them across your week, and see a live weekly MTQ score for every muscle before you train.
Build comprehensive workout plans directly in the browser and share them effortlessly with your clients.
RepRecord's MTQ model converts your sets into parts-weighted effective sets, then feeds them through an exponential saturation curve calibrated per muscle, meaning training quality is quantified, not guessed.
Volume sufficient for maintenance, but unlikely to produce significant growth.
The lowest training volume that still produces muscle growth and strength gains.
The sweet spot where your muscles adapt most efficiently to training stimulus.
The upper limit your body can handle and recover from. Exceeding it leads to regression.
Create reusable workouts from the full exercise library, drag them onto each day, and instantly see a weekly MTQ score for every muscle group calculated with the same algorithm as the app.
Parts-weighted effective sets, muscle-specific weeklyK parameters, and the exponential saturation model all running live in the browser.
