Why Iron Progress
Every chart on screen has to earn its spot. If a number doesn't help you decide what to do next session, it doesn't make it in.
Big tap targets. RIR per set. Drop sets and myo-reps with one tap. A warm-up calculator that does the math while you load the bar.
Plate calculator & warm-up sets
40/60/75/90% ramp with rest times suggested per set.
Audio cues even on a locked screen
Voice tells you the next set's weight × reps × RIR. Generated on-device, no servers.
Supersets, drop sets, myo-reps
Native protocol support, not just notes in a comment field.
The WRSI (Workout Relative Strength Index) compares each session to your maximum. The 5-factor recovery model warns you before you over-reach. Volume Landmarks (MEV / MAV / MRV) per muscle group keep your weekly programming honest.
Per-workout intensity vs. your own max.
Renaissance-style volume landmarks.
Auto-suggested at 60% when fatigue spikes.
Per-muscle recovery readiness on the home screen.
Most apps treat a 90 kg bench as the same accomplishment for a 22-year-old and a 55-year-old. We don't. Iron Progress factors in age curves and bodyweight ratios so 'Intermediate' actually means something.
"The Big 6": Squat, Deadlift, Bench, Overhead, Row, Pull-up. The lifts that say something about overall strength. Isolations are tracked separately.
Progression suggestions per exercise based on your last sessions. Deload advisor when accumulated fatigue says enough. Exercise deep-dives with e1RM trend, best sets and PR breakdown.
Light theme for the outdoor gym, dark for the basement. Big tap targets for sweaty fingers.
Local. Private. Yours.
Iron Progress runs entirely on your iPhone. Workouts, exercises, plans, profile: they live in your device's storage and stay there. There is no Iron Progress server. There is no account. There is nothing for anyone to leak.
Zero analytics tools. Zero ads. Zero third-party data-collection libraries, not even crash reporting.
No email, no password, no sign-up. Install, train, done.
Off by default. When you turn it on, it goes through your own iCloud, not ours. Switch off any time.
JSON export with one tap. Wipe everything from Settings. Uninstall = total data removal.
Apple HealthKit and iCloud sync are the only optional integrations. Both are opt-in, both stay between you and Apple, and both can be revoked in iOS Settings at any time. Subscriptions go through Apple StoreKit. Iron Progress only ever sees the transaction status, never your payment data.

I'm a licensed fitness trainer. I built Iron Progress because I wanted to track my own progress and adjust my training based on what my body was actually doing. With scientific foundations where they apply, and judgment where they don't. None of the apps I tried really convinced me. So I built the one I'd want to use.

The full logging engine is free: sets, RIR, drops, supersets, myo-reps, plate calc, history, strength standards, volume bars per muscle, PR detection, HealthKit. Pro adds deeper analytics (WRSI trends, exercise deep-dive, volume radar), smart coaching (progression suggestions, deload advisor, fatigue trend) and iCloud sync across all your Apple devices.
WRSI (Workout Relative Strength Index) is computed locally from your sets and your historical bests. The strength standards behind it are sourced from established literature — Rippetoe, NSCA, Saeterbakken, Contreras, McGuigan, Hughes, Miller — adjusted for your age and bodyweight.
