Features
Everything a serious lifter needs
PR Foundry handles the whole loop: generating the week's plan, logging every set down to your last AMRAP rep, charting your progress, and optionally bringing in the AI you already use to program around your real numbers.
Planning
Weekly Workout Planner
Generates the week's sessions for the selected program and subprogram, and lets you step through every week of the cycle.
Warm-up Ramps
Every working weight gets a standard, plate-rounded warm-up ramp: empty bar up through ascending percentages, with the reps dropping as the weight climbs.
Mesocycle Overview
A calendar-grid view of the full training cycle so you always know where you are in the block.
Tracking
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.
Set Types, Supersets & Giant Sets
Straight, AMRAP, paused, tempo, and dropsets. Group accessories so the rest timer applies between rounds.
Previous-Session Carry-over
Shows what you did last time and pre-fills accessory weights so you can pick up where you left off.
Custom Exercises
Add your own movements and specialty bars to any program.
Progress
Progress & Analytics
1RM progression, weekly volume, and volume broken down by muscle group.
Body Measurements
Track bodyweight and tape measurements over time alongside your lifts.
AI & Cloud
Bring Your Own AI
Connect Claude, ChatGPT, or another MCP client so the AI you already use can read your training and write a program built around you.
AI Program Library
Programs your AI pushes show up as a “User AI Generated” method, with each one a sub-program you can pick. Generate any week and the weights snap to the plates you own, with warm-ups filled in.
Full Multi-week Programs
Your AI can hand over a whole multi-week block at once, not just a single week. Switch between your AI programs whenever you want; your logged history stays put.
Opt-in Cloud Sync
Sign in with Apple or Google to mirror your training to the cloud and pick it up on another device. Off by default; the app stays fully usable without it.
Web Dashboard & Connections
View your synced training in the browser, see which AI clients are connected, disconnect any of them, and export or delete your data.
Data & Privacy
Units & Appearance
Full lbs/kg support throughout, plus System / Light / Dark themes.
Data Export
Export your full history as JSON or CSV through the iOS share sheet. Your data stays yours.
