Your sets, measured. Your progress, undeniable.

Not a tracker. A better way to train.

FAQ

Quick answers.

What does RepSense actually measure?
Every rep's concentric (lifting) and eccentric (lowering) tempo, plus optional isometric holds. You get live pacing on the watch and a full rep-by-rep breakdown on iPhone showing consistency, control, and where fatigue changed the movement.
Do I need my phone while lifting?
No. The entire session runs on Apple Watch. iPhone syncs automatically and is there for planning and review.
Does it tell me when to increase weight?
RepSense surfaces the data that makes that call for you: volume trends, consistency across sessions, per-set performance. When your numbers are stable and controlled, the next step is obvious.
Is my data private?
Completely. No accounts, no cloud sync, no social features. Your training data stays on your devices.
What do I need to use it?
An iPhone and an Apple Watch. Download RepSense from the App Store and you're ready to go.
