Ironmetrics tells you exactly what weight and reps to do next — so you just show up and lift. From your first workout to your thousandth.

Most gym apps are spreadsheets with a paint job — you do all the thinking. Ironmetrics does the thinking: it reads your history and hands you the next set.
Every personal record, your weekly volume, your estimated 1RM — the receipts that you're actually progressing, at a glance.
Offline-first. Log in a basement gym with zero signal — everything syncs the moment you're back online. Your data is always yours, exportable anytime.
A built-in plate calculator ("what goes on the bar?") and auto-generated warm-ups take the intimidation out of your first sessions — then grow with you as you advance.
Beginners get automatic progression so they build muscle without learning to program. Experienced lifters get the depth — RPE, estimated 1RM, custom programs, per-gym equipment profiles — without slowing down.
Free for 14 days — then $4.99/mo or $39.99/yr
