MrGripper is a grip-strength tracker for iPhone: dynamometer tests with a left–right symmetry score, per-hand logging, and PRs per exercise, equipment, load, and hand. It works with any dynamometer or gear you already own — grippers, hangboards, rings, bands, pinch blocks. No Bluetooth lock-in. You type the number. Free to download. Optional Pro is $4.99/month or $29.99/year. Built for grip sport, climbing, grappling, heavy pulls, and rehab.
Hey Product Hunt — I'm Rinalds, a solo iOS developer in Latvia.
I built MrGripper because every gym logger I tried treated grip as one more exercise slot, and the dedicated tools wanted me to buy their sensor first.
MrGripper is a grip-strength tracker for iPhone. You can:
• enter readings from any dynamometer you already own (no Bluetooth pairing)
• log crush, pinch, and timed holds per hand
• see a left–right symmetry score
• keep PRs per exercise, equipment, load, and hand
It's free to download. Pro is optional ($4.99/mo or $29.99/yr).
I'd genuinely like to know: if you train grip, what's the number you wish your current app showed you?
