About

Repstrack

Features
Read full description

Repstrack is the workout tracker built around one goal: getting stronger every week. Log your training, follow your plan, and let Repstrack tell you exactly when to add weight or reps. TRAIN SMARTER WITH PROGRESSIVE OVERLOAD Repstrack analyzes every session and suggests your next targets — "Try 62.5 kg × 8, you hit 4×8 at 60 kg last time." Accept with one tap or adjust to how you feel. When progress stalls, Repstrack spots the plateau and suggests a deload before you waste weeks spinning your wheels. LOG WORKOUTS IN SECONDS Your last session's numbers are always visible while you lift. Repeat a set with a single tap, and the rest timer starts automatically — with a notification when it's time for your next set. Track weight, reps, RPE, and set types across a library of 200+ exercises, or add your own. PLAN YOUR TRAINING Build reusable workout templates and organize them into weekly programs — Push/Pull/Legs, Upper/Lower, or anything custom. Your home screen shows today's session, pre-filled with targets based on your last performance. CELEBRATE EVERY PR Repstrack automatically detects weight PRs, rep PRs, volume PRs, and estimated 1RM records the moment they happen. Watch your strength climb with per-exercise charts for estimated 1RM, top set weight, and training volume, plus weekly volume per muscle group. WORKS COMPLETELY OFFLINE No signal in the gym? No problem. Log everything offline — it syncs automatically when you're back online, across all your devices. YOUR DATA, YOUR RULES Sign in with Apple, Google, or email. Export your complete training history anytime, and delete your account and data whenever you choose. Whether you're chasing your first bodyweight bench or your third year of training, Repstrack turns "did I lift this last time?" into a plan you can follow. Download Repstrack and make every session count. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
