About
PR Foundry is a strength app for powerlifters and serious lifters. Pick a program, set your maxes, and it builds your training week from the real published protocol. Log every set as you go, and it keeps score.
Nine programs are included, each built to match how its author actually wrote it:
Westside Conjugate, Sheiko, Smolov, Calgary Barbell, 5/3/1, nSuns 531 LP, GZCL, Classic Strength (Texas Method, Madcow 5x5, StrongLifts 5x5, Starting Strength), and Bullmastiff. Most come with their known variants, like Sheiko 29 through 40, Smolov Jr., 5/3/1 Boring But Big, and the GZCL Rippler.
Your week is generated from each program's own sets, reps, and percentages, then mapped to your 1RMs (with a Training Max where the program uses one). These are the actual programs, not generic logging dressed up with their names.
TRACKING
- One screen per exercise, with warm-up ramps and working sets
- Log weight, reps, and RPE, then auto-advance to the next set
- A rest timer that starts on its own and adjusts to the effort you logged
- AMRAP top sets, plus paused, tempo, and drop sets
- Supersets and giant sets
- A live PR banner when a set beats your estimated 1RM
- Last session carries over, so accessory weights pre-fill
TOOLS
- A plate calculator that draws exactly what to load on one side of the bar, using your own plate inventory and bar weight
- 1RM manager and calculator (Epley, Brzycki, Lombardi)
- RPE and RIR calculator
- Charts for estimated 1RM, weekly volume, and volume by muscle group
- Body measurements over time
- Works in lbs or kg
