## What is Iron Calc?

Iron Calc is your offline strength companion — fast, private, and built for the
gym. No account, no internet required, no data leaving your phone.

• 1RM CALCULATOR — Estimate your one-rep max from any set using three proven
  formulas (Epley, Brzycki, Lombardi), with a full training-percentage breakdown
  (50%–95%) so you know exactly what to load.

• PLATE LOADER — Enter a target weight and see precisely which plates to put on
  each side of the bar, with a clean visual of the loaded barbell. It respects
  the plates you actually own.

• RPE & WARM-UP TOOLS — Convert between RPE and load, and auto-generate warm-up
  ramp sets up to your working weight.

• WORKOUT LOG & PRs — Log your sets and the app automatically tracks your
  personal records per exercise.

• PROGRESS CHARTS — Watch your estimated 1RM trend over time, and export your
  full log to CSV.

• REMINDERS & WIDGET — Optional daily reminders that motivate you with your own
  records, plus a home-screen widget showing your top PR at a glance.

• MADE FOR YOU — Dark, light & auto themes, five accent colors, haptics,
  kilograms or pounds, and full support for English, Spanish, Arabic (RTL) and
  French.

100% offline. Your data stays on your device.
