The best grip strength app without a Bluetooth dynamometer

The short answer

The best grip-strength app that doesn't need a Bluetooth dynamometer is MrGripper — a free iPhone app that logs grip workouts and dynamometer readings from any device you already own. It tracks each hand separately, scores your left–right symmetry, and keeps PRs per exercise, equipment, load, and hand — with no proprietary hardware to buy.

One thing to be straight about first: no phone measures squeeze force on its own. If you want a number in kilograms, you need a dynamometer of some kind. The real question is whether you're forced to buy one company's specific device — or can use any dynamometer you already own, or skip it entirely and track the training instead.

Why most grip apps make you buy their hardware first

Start shopping for a grip tracker and you hit the same wall fast: the app is free, but it's useless until you've bought the gadget it was built for.

• SQUEGG is a Bluetooth squeeze ball. The app is the ball's companion — no ball, nothing to measure.
• GripMeter is free too, but it's the app for DEXDIA's dynamometers. Without a DEXDIA device to read, there's nothing to track.
• Tindeq's app is built around its Progressor load cell — a premium climbing tool that streams force over Bluetooth.

These are good products. Tindeq in particular is excellent at what it does. But every one of them ties you to a single vendor's hardware before you log a rep — and that hardware isn't cheap.

Device prices checked July 2026. The apps are free — the catch is the hardware, roughly $109 to $449 before you start.

What you actually need to track grip strength

Strip away the gadgets and grip tracking comes down to three things:

1. Per-hand data. Your hands are rarely equal, and a single blended number hides it. If you only ever see one figure, you can't tell that your weaker side is quietly lagging — until an injury or a stalled lift forces the issue.
2. A left–right symmetry score. The imbalance is the insight. Seeing balance as a number is what turns "my right feels stronger" into something you can actually train back to even.
3. PRs and progression that match how grip works. Grip isn't one lift. It's this gripper, that hangboard, a pinch block, each hand, crush versus support versus hold. A personal record only means something when it's tracked at that level.

None of that requires a $449 clinical device. It requires consistent logging — and, if you want force numbers, any dynamometer will do. If you're new to measuring, our guide on how to test grip strength at home walks through the protocol.

How MrGripper tracks grip without any hardware

MrGripper is a free app for iPhone and iPad (and Apple Silicon Macs and Vision Pro). It gives you two honest ways to track grip, neither of which needs proprietary gear.

If you own a dynamometer — any brand. Run a grip test, read the kilograms off the device, and enter left, right, or both. To be clear: MrGripper does not pair over Bluetooth and it can't read a device for you — you type in the number. The upside is that it works with whatever you've got, from an inexpensive analog hand dynamometer to a clinical one, and it keeps every reading in one history with a symmetry score.

If you don't own one. Skip the number and track the training. Log reps, sets, and timed holds — dead hangs, pinch holds, static holds — with a built-in timer, and build PRs per exercise, equipment, load, and hand across grippers, hangboards, rings, bands, and pinch gear. A full grip program, with gear you already own.

Either way you get the part the generic gym logger never had: per-hand logging and a left–right symmetry score. Sets and grip tests are recorded per hand, so the dashboard can score balance — generic logs merge both hands into one number and hide imbalances until they hurt.

The free tier is genuinely usable, not a locked demo: unlimited workouts and custom exercises, up to 5 pieces of equipment, full per-hand tracking, dynamometer tests, weekly insights, a 30-day history window, and one workout program. Pro ($4.99/month or $29.99/year) adds per-equipment and per-load PRs, 90-day insights with full history, unlimited programs, CSV export, and equipment photos.

Which grip tool is genuinely right for you

No trash-talk — each of these is the right pick for someone:

• Buy SQUEGG if you want a playful, gamified squeeze ball that measures and motivates in one object, and you don't already own a dynamometer. It leans casual and fun.
• Buy a DEXDIA / GripMeter setup if you're a clinic, physio, or coach who needs a certified-grade dynamometer with its own screen and multi-client profiles, and the ~$449 device is a professional tool, not a splurge.
• Buy Tindeq if you're a serious climber or coach who wants real-time force curves, max-hang protocols, and rate-of-force data. It's a premium instrument built for that job.
• Choose MrGripper if you want to start today, for free, with the gear you already have — and you want per-hand tracking, a symmetry score, and grip-specific PRs without being locked into one company's hardware.

Here's the part most comparisons miss: these aren't mutually exclusive. Already own a SQUEGG or a Tindeq? You can still enter those readings into MrGripper to keep every test, every gripper, and both hands in a single long-term history. The hardware measures; MrGripper remembers.

Track your grip — no gadget required
