Why I built it

Every training app I tried was a spreadsheet with a login. They record what you did. None of them tell you what to do next, which is the only part that is hard.

Gymingify picks your split, tracks every set, and then makes a call: add weight, push for reps, or hold. It shows the reasoning next to the exercise, so you can disagree with it.

Gymingify on desktop: a front and back anatomical figure with the shoulders and triceps highlighted, a week 10 deload notice, and exercise cards showing all-time personal records.
Today is a push day, so the app highlights what it is about to work. The deload notice appears on its own.

How it works

It reads your history, not just your last set
Two clean sessions at a weight moves you up. One bad session does not move you down. The suggestion says which rule fired.
It knows what today costs you
The anatomical map shows the muscles this session actually loads, and the week counter raises a deload prompt when fatigue has been stacking.
Your data stays yours
Everything lives in the browser. There is no account and no server. You can export the whole history as one JSON file and import it on another device.
It works with no signal
Installed to the home screen it runs offline, which matters in a gym basement.
