Stop guessing

How it actually works

Three states. No test, no guessing, no AI making it up.

Most apps ask you to max out on day one, or hand you a number an algorithm invented. Charge1 asks what you actually lifted, twice, then takes over.

Blank

First time on a lift, the box is empty. You enter the weight and reps you'd normally do. Nothing invented, nothing guessed.

Predicted

Second time, it shows last session's numbers as a prediction, clearly labeled as one — not a fact, just your own recent history.

Validated

From here, the progression engine takes over. Clean reps, it climbs. Miss the target, it eases. Your data, not a formula's guess.

Your macros, day one

Set your stats. Get your split, not a spreadsheet.

Calories, protein, carbs and fat, computed from your own weight and body fat the moment you finish setup. A suggestion to hit, not a food log to maintain.
