Why PR Foundry
Not a workout log. A programming engine.
Nine programs, built to spec
This isn't generic workout logging. Each program is generated straight from its author's published protocol, down to the exact sets, reps, percentages, and weekly progression.
Private, and on your device
There's no account and no tracking, and the app makes no network calls. It works on the gym floor with no signal, and nothing you log ever leaves your phone.
Auto-regulated rest & RPE
The rest timer adapts to the effort you actually log, with durations you control per RPE/RIR band.
Built for the barbell
Plate calculator, warm-up ramps, Training-Max math, and proper AMRAP sets. These are the details a serious lifter actually cares about.
9 Methodologies
Real programs, built from the source
Each plan comes straight from the program's published protocol: the exact sets, reps, percentages, and weekly progression, all mapped to your 1RMs.

Built-in Tools
The barbell math, handled
- Plate Calculator — Enter a target weight and see exactly which plates to load on one side of the bar, drawn as a side-view diagram with gaps so duplicate plates are countable. Supports custom plate inventory, bar weight, and collars.
- 1RM Manager — Store and update your estimated one-rep maxes per lift. These drive the weights in every generated plan.
- 1RM Calculator — Estimate a 1RM from any weight × reps using Epley, Brzycki, or Lombardi, with a projected rep-max table.
- RPE / RIR Calculator — Enter a 1RM, working weight, and reps to get the implied RPE, reps-in-reserve, and percentage of 1RM.
