RepForge - Built For Strength

Velocity-based training for powerlifters: measure bar speed from your iPhone camera, program by %1RM and RPE, and let an AI coach adapt your plan.

RepForge is built for powerlifters who program by percentage of 1-rep-max (%1RM) and RPE, with the plan driven by data rather than guesswork. Measure bar speed straight from your iPhone camera, no extra hardware, then let those numbers shape your %1RM and RPE targets.

Most apps treat RPE and velocity as something you note after a set. RepForge makes them the input that drives the plan, the workflow serious lifters and coaches otherwise piece together by hand in spreadsheets.

VELOCITY-BASED TRAINING Measure bar speed and bar path from your iPhone camera using our own custom-trained detection model, with no extra hardware Build a separate load-velocity profile for each exercise, variation, and equipment setup, since these relationships differ from lift to lift Turn measured bar speed into weight and %1RM/RPE recommendations for your next set See whether you are moving the same load faster as a block progresses

WORKOUT TRACKING Log every set with weight, reps, and RPE, with bar velocity attached from a recorded video Film any set and review it straight from your log Built-in rest timer that shows on your lock screen with iOS Live Activities

VIDEO ANALYSIS Overlay the set's data (reps, weight) and measured metrics (range of motion, RPE, bar speed) onto the clip Trim to the exact rep and pinch to zoom in on key positions Play two lifts side by side and synchronized, to compare technique between attempts or across weeks Export the annotated or side-by-side video to share with a coach

TRAINING PROGRAMS Build multi-week, phase-based programs the way powerlifting blocks are actually structured Prescribe each set by %1RM or RPE, then log how it actually felt to see where the plan and reality diverge

PROGRESS & ANALYTICS Chart estimated 1RM for every lift and watch strength trend across blocks View each lift's load-velocity profile and how it shifts as you train See training volume and program adherence at a glance Get a readiness read from your recent sessions to help decide when to push or back off

CALCULATORS One-rep-max estimator from your submaximal work sets RPE calculator to find the target weight for any reps-at-RPE Competition scoring: Wilks, DOTS, IPF GL Points, Glossbrenner, McCulloch, and more

AI COACH Smith, an AI coach that reviews your training and checks in on how sessions are going Suggests specific adjustments like exercise swaps, deloads, and phase extensions Can draft a full periodized program from a short back-and-forth Every suggestion is a change you accept, reject, or edit, and nothing is applied on its own Off by default, opt in whenever you want

BODY WEIGHT & RECORDS Log body weight and watch it trend on interactive charts Personal records tracked automatically for every exercise Pull your best competition squat, bench, and deadlift into the scoring calculators

SYNC & PRIVACY Automatic iCloud sync keeps your data backed up and current across devices Your data stays in your private iCloud, with no RepForge account required
