Progress should be obvious.

Your old numbers should not live in Notes, screenshots, or memory. Setz turns weight and reps into a clear comparison before you rack the bar.

Know if the lift moved.

Setz compares completed volume set by set. It shows when you are ahead—and when the work fell short—then keeps the next target clear.

Train the week. Not one favorite lift.

The seven-day muscle view shows what needs more work, what is on target, and what has already had enough.

How Setz protects your data

Questions before your first set.

What is a progressive overload tracker?

A progressive overload tracker records weight, reps, and completed work, then shows the last comparable set so you know what to beat today. Setz does that during the set, not only in a chart after the workout.

How do I track progressive overload in the gym?

Record each working set with the exercise, weight, and reps. Compare the same movement with your last session, then check exercise totals and weekly muscle-group volume instead of relying on memory.

Is Setz just a workout log?

No. A notes app stores numbers. Setz puts last time beside this set, shows whether the work is ahead, matched, or under, and connects the result to the lift, workout, and week.

Do I need an account to use Setz?

No. You can build a split and log a workout in the browser now without an account. The iPhone beta is local-first, so detailed workout entries stay on your phone.

Can I use my own workout program?

Yes. Start with a guided split, repeat a saved workout, build your own, or add an exercise while the session is running. History stays with the lift.

When can I use Setz on iPhone?

The browser workout builder and logger are available now. The native iPhone app is preparing for TestFlight; ask for beta access and we will send an invitation when the build is ready.

Put last time beside this set.

Open Setz, choose the workout, and know exactly what you are trying to beat.
