Track the work.
See the recovery.
TRAK logs your lifts in seconds, maps muscle recovery on a body heat map, and surfaces insights computed from your actual training. Built for lifters who care about progressive overload.
Free to download. iPhone, iOS 17 or later.
What does TRAK include?
Live demo
Know what to train before you train
This is the Recovery Map from the app, running on a sample week of logging. Every muscle group sits on one readiness scale that decays as you recover — tap a muscle or a row to see its state.
In the app, this is computed from your own sets — what you lifted, how hard, and how long ago.
