Never lose track of your sets again: monitor intensity, volume, and RPE while using advanced INOL fatigue modeling to optimize your strength and hypertrophy gains.
Researchers manipulate countless variables to figure out what drives hypertrophy and strength. With Set Tracker 2, you don’t have to depend on their research—you can find out for yourself.
Log your weight, reps, volume, intensity, and rest intervals. Track the data, analyze the variables, and discover exactly what works best for your own body and your specific goals.
Want to go deep? Use our advanced built-in charts to visualize your growth, or export your raw data to analyze it yourself in Excel or your software of choice.
Don't want to play scientist? No problem. Use it as a straightforward logging tool to keep track of your workout history, or simply rely on it to check what set you're currently on (because we all lose count).
CORE FEATURES:
BE YOUR OWN LAB
Track everything: weight, reps, RPE, work time, and rest duration. Export your data to CSV anytime for your own spreadsheet analysis, or let our built-in performance matrix do the math for you.
GAMIFIED PERSPECTIVE
Stay motivated. Your lifter avatar collects "XP" (tonnage moved and intensity shifts) after every logged set, putting your hard work into perspective in real-time.
LIVE ACTIVITY REST TIMERS
When you enter rest mode, your timer securely locks into the Dynamic Island and Lock Screen. Browse other apps or lock your phone—the Core Reactor keeps your intervals perfectly timed outside the app.
VISUAL CANDY
Customize your HUD with 4 distinct interface themes: Cyberpunk (neon data streams), Stealth (ultra-minimal), Minimal (clean native iOS), or Aura (warm and rounded).
APPLE WATCH TELEMETRY
Leave your phone in your gym bag. The Apple Watch app stays in perfect sync with your iPhone in real-time. Log a set on your wrist, and your phone updates instantly.
STRENGTH STANDARDS
Input your body weight to unlock your true lifter profile. Track your IPF GL, DOTS, or Wilks scores, and see how your Big Three lifts stack up against global strength standards.
ZERO BS GUARANTEE:
Set Tracker 2 was built by a lifter, for lifters.
