Grip Strength: MrGripper is an iPhone app for logging grip workouts, running left/right grip tests, and tracking per-hand personal records — clear numbers, not guesswork.
Built for gripper training, climbing, grappling, calisthenics, heavy pulls, and rehab — anyone who wants hand strength they can measure.
Free to download · Optional Pro subscription · No special hardware required
Inside the app
A grip tracker that looks like it means it
Native iOS design, bold numbers, and screens built around one job: making your grip training measurable.
Today at a glance: volume, holds, consistency, and hand symmetryLog every set — left and right hand, separately or togetherGrip tests with per-hand readings and a symmetry scoreBuilt-in timer for dead hangs, pinch holds, and static workPRs that match how you train: per exercise, equipment, load, and hand
How it works
From first set to visible progress
Pick your gear and goals
Onboarding seeds your equipment types and exercise library from what you actually train with — grippers, hangboards, rings, bands, or pinch gear.
Train and log in seconds
Save workout programs with target sets, reps or hold time, and rest. Tap a template, train, and log each hand in a few taps.
Test your grip
Run dynamometer grip tests for the left, right, or both hands and get summaries with a symmetry score.
Watch the trend, not one session
Weekly insights track consistency, hold time, and load volume separately, and PRs update per exercise, equipment, load, and hand.

Who it's for
Purpose-built for hand and grip work
Not a generic gym log with "grip" bolted on. Every screen assumes your training happens at the hands.
🤜
Gripper & grip sport training
Track closes and rep bests for each rated gripper in your gear library. Per-equipment and per-load PRs show exactly which spring you beat, and when.
🧗
Climbers & boulderers
Log hangboard sessions, pinch work, and max hangs with the built-in timer. Per-hand records make contact-strength gaps visible before they become injuries.
🥋
BJJ & martial artists
Grip decides grips. Train crush and hold endurance, log timed holds, and watch left–right balance so your weak-side grips catch up.
🤸
Calisthenics athletes
Dead hangs, bar holds, and support work in one flow — max reps and max-duration holds both count, and both get tracked.
🏋️
Lifters with stalling pulls
When deadlifts and carries fail at the hands, train grip like a lift: programmed sets, logged loads, and volume trends you can act on.
🤕
Rehab & return to training
Record dynamometer readings per hand and watch the symmetry score close the gap — steady, measurable progress you can share with your physio.
Training guides
Learn the training, then track it
Practical, no-fluff guides on testing and building grip strength — written to answer the question first and mention the app second.
Yes. The free version includes unlimited workouts and custom exercises, up to 5 pieces of equipment, full per-hand tracking, dynamometer grip tests, weekly insights, a 30-day history window, and one workout program.
An optional Pro subscription ($4.99/month or $29.99/year) adds per-equipment and per-load PRs, equipment photos, 90-day insights with full history, unlimited programs, and CSV export.
Do I need a Bluetooth dynamometer or other special hardware?
No. Unlike trackers tied to a proprietary device, MrGripper works with whatever you already own — grippers, hangboards, rings, bands, pinch gear, or custom tools. Grip-test readings from any dynamometer are recorded by entering the number.
Can I track my left and right hand separately?
Yes. Every set can be logged per hand or both together, grip tests record left, right, or both, and a symmetry view shows the balance between hands. Learn more about fixing a weaker hand.
Which devices does MrGripper run on?
iPhone and iPad (iOS/iPadOS 18.0 or later), Mac (macOS 15.0 or later on Apple Silicon), and Apple Vision Pro (visionOS 2.0 or later). The interface is available in English, German, Russian, and Spanish.
Does the app work offline?
Yes. MrGripper is offline-first: log workouts and review your training data anywhere, no connection required.
What data does MrGripper collect?
The App Store privacy label lists only Usage Data and Diagnostics, collected in a way that is not linked to your identity. Details are in the privacy policy.
How do I test my grip strength at home?
Use a hand dynamometer for a measured reading, or practical proxy tests like a max dead hang or a rated gripper close. Test each hand separately and repeat under the same conditions so results stay comparable. Learn more in the testing guide.
Your grip is trainable. Prove it with data.
If you train with grippers, hang from boards, pull heavy, or grip-fight for a living, MrGripper turns that work into numbers you can watch improve — starting with your first logged set.
