Heavier on your phone

Heavier is a phone app: you log at the rack, offline when the signal is gone, and it lives on your home screen like any other app. The desk, this page, is the computer's side: plans, history and analysis.

Heavier is in beta. Once every function is in place and the app is stable, we will look into making it an iPhone and an Android app. Until then, the app on your home screen is the app: it works offline and keeps what you log on the phone until it can sync.

Sign in on the phone

The app asks for a one-time code. Make one here and type it on the phone; it works once, for a few minutes.

Not for use on a computer. The app is built for a phone in your hand at the gym: one column, a thumb's reach, a number keypad. In a desktop browser it works, but only to look at how it works.
