Introduction

1RM is a straightforward one-repetition maximum calculator for strength training. The 1RM app estimates maximal lifts using established formulas and provides practical training loads. Users can track progress and compare estimates for different exercises with 1RM in kilograms or pounds.

Features

  • Multiple estimation formulas: Epley, Brzycki, Lombardi and others for cross-checking results
  • Automatic conversion between kilograms and pounds
  • Percentage-based training tables to generate working sets
  • Exercise history and simple export to CSV for tracking progress
  • Offline operation with a minimal, easy-to-use interface

How it works

Enter the weight lifted and number of repetitions, choose a formula, and the app calculates an estimated one-rep maximum and common percentage loads. Results are descriptive and include suggested working weights; they are estimates and not a substitute for professional coaching.

Compatibility and safety

1RM runs on most Android devices and uses only the data you enter locally. Always warm up, use proper form, and consult a trainer if you have concerns about lifting heavy loads.
