PlateMath turns plate-counting into an instant answer. Set how many plates are on your adjustable dumbbell and see the total weight in kilograms — handle, locking screws and all. WHAT IT DOES • Instant total — pick your plates, read the weight in kg (and lb) • Symmetric or asymmetric loading — mirror both sides, or set each side on its own • Counts the 5 lb handle and locking screws automatically • Target planner — enter a goal weight and PlateMath suggests the exact plates to load, never going over • Your plates, your inventory — tell it how many of each plate you own so suggestions only use what you have CLEAN AND FAST No account, no ads, no tracking, works fully offline. Open it, get your number, get back to your set. Designed for Ironmaster® Quick-Lock® adjustable dumbbells and the micro plate kit. Not affiliated with, endorsed by, or sponsored by Ironmaster. What's New (v1.0): First release of PlateMath.
