Gryper: Workout & Muscle Log

Gryper is a workout tracker built for serious lifters — not casual gym-goers.

Log your sets in seconds, see exactly which muscles you're training with a full-body heatmap, and use real hypertrophy science (MEV / MAV / MRV) to know when you're under-training, in the sweet spot, or pushing into overtraining.

START IN SECONDS — NO ACCOUNT NEEDED • Open the app and log your first workout immediately — no sign-up, no email, no wall • Create an account whenever you're ready and everything you logged comes with you • Sign in with Apple, Google, or email

SWITCHING FROM ANOTHER APP? • Import your full Hevy history from a CSV export — every session, set and exercise • Guided review step maps each of your exercises to Gryper's library, or creates it as a custom exercise with the right muscles tagged • Merge or replace on re-import, so nothing gets duplicated

LOG WORKOUTS FAST • Live workout screen with set-by-set tracking for weight and reps • Built-in rest timer that starts the moment you log a set • "Last time" reference and smart ghost values so you never guess your numbers • Kilograms or pounds — switch any time, every number converts • Swipe to delete a set; start from a saved routine or fire off an empty workout instantly • Changed the plan mid-session? Gryper offers to update that routine — or save an ad-hoc workout as a new one

SEE YOUR MUSCLES WORK • Front and back full-body muscle heatmap coloured by training intensity • Male and female anatomical body maps • Second lens for recovery, so you can see what's still fatigued before you train it • Instantly spot neglected muscle groups and lagging body parts • 36 muscle groups mapped across 170+ exercises

TRAIN BY THE NUMBERS • Weekly volume, total sets, and day-streak tracking • Push/Pull and Upper/Lower balance so your programming stays symmetrical • Volume trends across your recent sessions • Automatic estimated 1-rep max (e1RM) and personal-record tracking • Dedicated drill-downs for muscles, strength, records and consistency • Set your own weekly session target and track against it • Every metric has a plain-English explainer — what it means, how it's calculated, what to do about it

MEV / MAV / MRV VOLUME LANDMARKS Gryper grades your weekly volume against evidence-based landmarks — Minimum Effective Volume, Maximum Adaptive Volume, and Maximum Recoverable Volume — so every muscle gets enough stimulus to grow without burning you out.

A REAL EXERCISE LIBRARY • 160+ exercises filterable by equipment — barbell, dumbbell, machine, cable, kettlebell, bands and bodyweight • Tracks more than weight × reps: bodyweight reps, weighted bodyweight, duration and distance • Add unlimited custom exercises and tag their muscles by tapping the body map • Build and save unlimited routines for push, pull, legs, or any split you run

WORKS WHERE YOU TRAIN • Offline-first — log full workouts with zero signal in the basement squat rack, syncs automatically when you're back online • Clean light and dark modes, switchable in-app • Fast, native, and distraction-free

Stop guessing. Start tracking what actually drives growth.
