## What is Good Gym Calculator?

Good Gym Calculator is the app you open between sets. No accounts, no feed, no clutter — just the three tools that actually get used on the gym floor.

GYM CALCULATOR
Work out your numbers in seconds instead of doing math with chalky hands.
- Estimate your one-rep max from any set and rep count
- Build percentage tables off any max, so you always know what "75% x 5" means today
- Convert between pounds and kilos instantly
- Figure warm-up jumps up to your working weight

LIFT LOG BOOK
A training log that takes seconds to fill in, not minutes.
- Record sets, reps, and weight for any lift
- Pull up your history for a movement before you load the bar
- Watch your best lifts move over weeks and months
- Everything stays on your device and stays yours

PLATE LOADER
Stop squinting at the bar and second-guessing the math.
- Enter a target weight and see the exact plates per side
- Choose your barbell weight for standard, women's, or training bars
- Set which plates your gym actually has, so you never get told to load something that isn't in the rack
- Works in pounds or kilos

BUILT FOR HOW YOU ACTUALLY TRAIN
Whether you're running a strength cycle, coaching a class, or just trying to add five pounds to your squat, the answers you need are one tap away. Big buttons, clean numbers, no scrolling past ads to find the field you want.

Load the bar. Log the lift. Get back to work.
