MrGripper - Track grip strength per hand — any dynamometer

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.
