Getting started

Welcome to Mettle

What makes Mettle different from every other app that tells you what to lift.

Most strength apps tell you what to lift. Mettle tells you why: because you topped the rep range, because you are four weeks from a deload, because your squat needs volume your bench does not.

It also meets you where you are. On day one the language is plain and reassuring. A year in, the same program gets described in the terms an experienced lifter actually wants. What changes is the explanation, never the quality of the plan underneath.

The four tabs

  • Today: the session waiting for you, or a recovery card if you have earned one.
  • Plan: the program, the training week, and the ability to edit any day.
  • Coach: a conversation grounded in your own program and history.
  • Progress: volume, duration, heart rate, tempo, records, and set-by-set history.
