# Zimetrix > Measure your max force, explosiveness and left/right symmetry in 10 seconds.

It is a smart isometric dynamometer the size of a remote
that, together with this app, shows you your real strength in kilograms after every session.

What gets measured gets improved. Stop programming loads from a 1RM you estimated three months ago and start training
with real data from this week.

HOW IT WORKS
1. Anchor the device to any fixed point (bar, rack, ring, strap or floor). Under 30 seconds.
2. Pull or push at 100% for a 5-second isometric test.
3. Analyze your results instantly in the app.

WHAT IT MEASURES
• Max force in kg, clinical-grade precision
• RFD (explosiveness): how much force you produce in 100, 200 and 300 ms
• Force-time curve for every rep
• Bilateral symmetry: left vs right difference, in %
• Isometric endurance: how long you hold near your max

WORKS WITH 30+ TESTS
Deadlift, squat, bench press, row, overhead press, pull-ups, curls, hand grip, rotators and many more.

WHO IT IS FOR
• Serious athletes: catch plateaus and asymmetries before you lose months (or get injured).
• Trainers and coaches: back every decision with objective data and track your athletes.
• Physiotherapy and rehab: quantify side-to-side deficits and progress.

THE APP
• Pair with the device in 2 seconds by scanning a QR code
• Every measurement saved forever and synced to the cloud
• Unlimited history and clean charts of real, not estimated, progress
• Compare by session, by side and over time
• Available in English, Spanish and Catalan
• Sign in with Apple or Google

Three minutes per session. Data that used to require a high-performance lab.

Use it once a week like a scale, but for real strength, power and explosiveness.

Note: Zimetrix requires the Zimetrix dynamometer device to take measurements. ## Rankings - #2,713,863 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.CAMERA` - `android.permission.INTERNET` - `android.permission.POST_NOTIFICATIONS` - `android.permission.READ_APP_BADGE` - `android.permission.RECEIVE_BOOT_COMPLETED` - `android.permission.RECORD_AUDIO` - `android.permission.REORDER_TASKS` - `android.permission.SYSTEM_ALERT_WINDOW` - `android.permission.USE_BIOMETRIC` - `android.permission.USE_FINGERPRINT` - `android.permission.VIBRATE` - `android.permission.WAKE_LOCK` - `android.permission.WRITE_EXTERNAL_STORAGE` - `com.anddoes.launcher.permission.UPDATE_COUNT` - `com.android.vending.CHECK_LICENSE` - `com.google.android.c2dm.permission.RECEIVE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.htc.launcher.permission.READ_SETTINGS` - `com.htc.launcher.permission.UPDATE_SHORTCUT` - `com.huawei.android.launcher.permission.CHANGE_BADGE` - `com.huawei.android.launcher.permission.READ_SETTINGS` - `com.huawei.android.launcher.permission.WRITE_SETTINGS` - `com.majeur.launcher.permission.UPDATE_BADGE` - `com.oppo.launcher.permission.READ_SETTINGS` - `com.oppo.launcher.permission.WRITE_SETTINGS` - `com.sec.android.provider.badge.permission.READ` - `com.sec.android.provider.badge.permission.WRITE` - `com.sonyericsson.home.permission.BROADCAST_BADGE` - `com.sonymobile.home.permission.PROVIDER_INSERT_BADGE` - `dev.zzlabs.musclezz.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` - `me.everything.badger.permission.BADGE_COUNT_READ` - `me.everything.badger.permission.BADGE_COUNT_WRITE` ## Similar extensions and apps - [Metric - Barbell Tracker](https://chrome-stats.com/d/com.coreadvantage.metric) — 3,919 users - [My Lift: Measure your strength](https://chrome-stats.com/d/com.powerlift) — 5,599 users - [Strength Measures](https://chrome-stats.com/d/com.exphys.strengthmeasuresapp) — 5 users - [GymTrackerPro](https://chrome-stats.com/d/gymtracker.pro) — 40 users - [Massimali Tracker](https://chrome-stats.com/d/com.skull85.massimalitracker) — 13 users - [Maximus 1RM Calculator](https://chrome-stats.com/d/com.maximus_1rm_calculator) — 8 users - [GripMeter Physio - Grip Tester](https://chrome-stats.com/d/com.dexdia.gripmeterphysio) — 396 users - [FORCE CLUB – carnet de muscu](https://chrome-stats.com/d/com.adas.forceclub) — 7 users - [MaxRep](https://chrome-stats.com/d/jp.mikhail.pankratov.trainingMate.android.prod) — 37 users - [GenosLift](https://chrome-stats.com/d/com.genoslift.genosliftapp) — 4 users - [1RM Pro: Strength Calculator](https://chrome-stats.com/d/com.eniac.calculadora1rm) — 100 users - [Iron Calc — Gym 1RM & Plates](https://chrome-stats.com/d/com.liveqbits.ironcalc) — 14 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/dev.zzlabs.musclezz)
