Measure Your
True Strength
IronChart measures force, power, and work from your weight lifting exercises in real-time. Attach your phone to the weight stack and let physics do the tracking.
How It Works
Three steps. No extra hardware. Just your phone and a weight stack.
1. Attach
Mount your phone securely to the weight stack using a phone holder.
2. Lift
Perform your exercise as normal. IronChart uses the accelerometer to track every rep.
3. Analyze
See your force, power, and work output. Track progress over time with real physics.
Real Metrics, Not Guesswork
⚡ Force Measurement
Know exactly how much force you generate through each phase of the lift — concentric, eccentric, and isometric.
💪 Power Output
Power = force × velocity. See how explosively you move the weight, not just how much you lift.
📈 Work Tracking
Total mechanical work done per set and session. The truest measure of training volume.
🔒 Privacy First
No accounts required. No tracking. No ads. Your training data stays on your device.
Stop Guessing. Start Measuring.
