Loved by lifters
Don't take our word for it
“I've tried every lifting app on the store. REPZ is the first one that gets out of my way — I log a set faster than I can rerack the bar.”
MMarcus T.Powerlifter · 3 yrs “Logging straight from my Apple Watch mid-set is a game changer. My phone hasn't left my gym bag in a month.”
PPriya N.CrossFit · daily “The live volume chart is low-key addictive. Seeing the number climb every session keeps me showing up.”
DDevon R.Hypertrophy · 5 yrs
“Hit three PRs last month and REPZ caught every one automatically. No spreadsheets, no math, just lift.”
SSofia L.Olympic lifting “The AI generator built me a push/pull/legs split in seconds that actually matched my gear. Genuinely impressed.”
JJames K.Home gym “Rest timers with haptics keep me honest. No more scrolling between sets and turning a 45-min workout into 90.”
AAmara W.Strength · 2 yrs
“Clean, fast, zero clutter. It feels like an app a lifter actually designed, not a spreadsheet with a logo.”
TTom B.Bodybuilding “Switched from a paid tracker and never looked back. The progress graphs alone are worth it.”
LLena F.Strongwoman “My whole gym crew is on it now. We compare weekly volume like it's a leaderboard.”

Frequently asked
Is REPZ free?
Yes — download and start logging for free. Every core feature, from set logging to live stats, works out of the box with no account required.
Do I need an Apple Watch?
Not at all. REPZ is great on iPhone alone. If you do have a Watch, you get wrist-based set logging and live heart rate as a bonus.
Where is my data stored?
Your workout history stays on your device and syncs privately through your own iCloud. We never sell or share your training data — it's 100% yours.
Can I bring my own routine?
Absolutely. Build any split by hand, or let the AI generator create one from your goal and available equipment in seconds.
Is REPZ on Android?
REPZ is built for iPhone and Apple Watch today. Android is on the roadmap — join the App Store to follow updates.
