Tracking. Simplicity. Precision.

FORM4 is built around three principles. Everything in the app follows from them.

Tracking
Load, reps and RIR for every set, with the previous set in view. The logbook is the product; everything else reads from it.
Simplicity
The fewest taps between you and the next set. Load is pre-filled from the last session; rest starts with one tap.
Precision
Half reps, sides, rest between sides, target ranges: the details that decide whether a set counts are first-class data.

Getting a program in

Build it by hand in the Program Builder, or photograph the sheet you already keep. Photo Import reads the sheet and builds a draft you review; nothing is saved until you confirm.

How progress is shown

FORM4 compares the sets that make sense to compare: the same exercise, the same set, across weeks of the same program. You see start vs last, load and reps over time, and your best set. No score.
