How it works

Order sets and rest times — or start from one of our predefined routines and make it yours.
Or use one of our predefined packs.
Put it on the calendar with a reminder, or begin training this second.
Your last session appears projected over the current one. That is Ghost Mode.
Previous session: 40 kilograms for 12 reps. Today: 82.5 kilograms for 8 reps.
Ghost Mode
TraceIron projects the data from your last completed session directly over the set you are working on. The number to beat is already on screen — you do not have to remember it, look it up, or trust it to a notebook.

Why it exists
I don't know if I'm actually progressing or just repeating the same session.
Your previous numbers sit on top of the current set, and estimated one-rep max is computed from your real history. Progress stops being a feeling.
Logging sets on my phone between rests pulls me out of the workout.
Confirm a set with one thumb and feel it land. Or don't touch the phone at all: check in from Apple Watch, the Dynamic Island, or a Lock Screen widget.
My data is held hostage by an app that charges for everything.
Unlimited workout and set logging on the free plan, synced through your own private iCloud. Premium adds export to JSON, CSV and Excel.
