Did you train
enough?

Gryper is a free workout tracker for lifters, on iPhone and Android. You log every set in one tap, or load plates on a bar without typing; Gryper maps each set onto an anatomical muscle heatmap and grades your weekly volume for every muscle against MEV, MAV and MRV, so you can see whether you trained enough, hit the productive range, or pushed too far.

Every set you log counts toward the muscles that exercise works. Gryper adds those sets up per muscle for the week and compares the total with three volume landmarks: MEV (minimum effective volume), MAV (maximum adaptive volume) and MRV (maximum recoverable volume). Below MEV means that muscle probably didn’t get enough work; between MEV and MAV is the productive range; past MRV is more than most lifters can recover from. Primary muscles get a full set of credit and secondary muscles part of one, usually half; warm-up sets don’t count. The landmarks are research-based starting points, not guarantees, and the map shows the result at a glance. Details: gryper.fit/guides/how-gryper-counts-sets.

They are weekly set ranges per muscle. MEV is the fewest hard sets that still produce growth. MAV is the range where most lifters grow best. MRV is the most you can do and still recover. Gryper uses published defaults for each of its 36 muscle groups; you can’t edit them yet. Full guide with every muscle’s numbers: gryper.fit/guides/mev-mav-mrv.

Each exercise in the library is mapped to the muscles it trains. When you log a set, those muscles light up on a front and back body map: after a session it shows what you worked that day, and across the week it colours each muscle by where its volume sits against MEV, MAV and MRV.

No. Tap a weight to load plates on a barbell, pick a dumbbell off a rack or drag the pin on a machine’s weight stack, and spin a dial for reps. You can also hold any cell and drag to move it one plate or one rep. If you prefer typing, the keyboard is one tap away, or set Number Entry to Keyboard Only in Profile.

Yes. On iPhone the rest countdown shows on the lock screen and in the Dynamic Island, with −15, +15 and Skip, and Gryper can alert you when rest ends. On Android it stays in an ongoing notification.

Yes. You can log a whole workout with no signal. Sets are stored on the phone and sync to your account when you are back online.

Yes, free to download on the App Store and Google Play, with no limit on workouts, routines or custom exercises, and you can start without an account. Everything in the app is free today. Gryper Plus, a paid tier for deeper analysis, is coming soon; logging and your own records and data will stay free.

Plus will add four things: readiness (estimated recovery of each muscle), balance analysis, strength trends across your lifts, and 90-day, custom and all-time views. Everything else stays free for everyone, including existing users: unlimited logging, routines and custom exercises, the muscle map and weekly MEV/MAV/MRV grading for 7 and 30 days, records, streaks, Hevy import and full export. When Plus launches, those four features move to Plus for free accounts too; nothing you have logged is ever locked or deleted, and a free trial of Plus is offered once you have logged 12 workouts. Prices will be shown in the app before you are asked to pay.

Offline you can log whole workouts, start and edit routines, use set entry and the rest timer, and see unsynced workouts in History; everything syncs when you are back online. The very first launch needs a connection to set up your guest profile. Signing in, syncing, exporting data, importing from Hevy and sending feedback need a connection, and export and Hevy import also need a free account rather than guest mode.

With a free account, every workout is saved to your account and syncs to any phone you sign in on; a guest profile is carried over when you create an account. To export, go to Profile → Export Data and choose an Archive (JSON) or a Spreadsheet (CSV) of your workout history, routines and body metrics. To delete everything, go to Profile, scroll to Delete Account, or follow gryper.fit/delete-account.

Lifters who follow a split or routine and want to know, per muscle, whether their weekly training is enough, usually intermediate lifters training for size and strength. Beginners can start on day one with a starter routine and simple logging. If you mainly want cardio tracking, a watch app or a social feed today, Gryper is not there yet.

Yes, publicly. Gryper is on Google Play for anyone with an Android phone (the closed test has ended), and on the App Store for iPhone (iOS 16.4 or later). Get it on Google Play: https://play.google.com/store/apps/details?id=fit.gryper.app

Yes. Export your full history as a spreadsheet CSV or a JSON archive at any time. From Hevy, import its workout CSV in Profile → Import from Hevy: workouts, sets, set types, RPE, notes and supersets come across; routines and body measurements do not. Step by step: gryper.fit/import-from-hevy.

Gryper is built for lifters who want fast logging and a muscle-level answer to “was that enough?”. On top of sets, reps and records, it maps every set onto a muscle heatmap and grades each muscle’s weekly volume against MEV, MAV and MRV. Logging is built around the gym itself: load plates, pick dumbbells off a rack, move the pin on a stack. Its free version has no cap on routines or custom exercises. Hevy and Strong do things Gryper does not yet, like cardio by time or distance and watch apps. Full comparison: gryper.fit/compare/hevy-and-strong.
