Why PR Foundry
Not a workout log. A programming engine.
8 real programs, faithfully implemented
Not generic workout logging — each program is generated deterministically from its author's published protocol: exact sets, reps, percentages, and weekly progression.
100% on-device & private
No account, no tracking, no network calls. It works offline on a gym floor with no signal, and nothing 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 first-class AMRAP sets — the details a serious lifter needs.

Everything a serious lifter needs
Weekly Workout Planner
Generates the week's sessions for the selected program and subprogram, and lets you step through every week of the cycle.
Exercise-by-Exercise Tracker
One screen per exercise with its warm-ups and working sets. Log weight, reps, and RPE, then auto-advance to the next set and exercise.
Adaptive Rest Timer
Auto-starts after each set with a duration you set per RPE/RIR band. On-screen circular countdown with ±30s and skip.
Personal-Record Detection
A live PR banner fires the moment a logged set beats your estimated 1RM.
Training Max & AMRAP Support
Proper Training-Max handling for 5/3/1 and nSuns, with AMRAP “+ sets” treated as first-class.
Progress & Analytics
1RM progression, weekly volume, and volume broken down by muscle group.
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.
