Who it’s for

Built for people living with energy-limiting conditions

It does not ask you to do more. It helps you do the right amount, for you, on the day you are actually having.

Know your energy

A daily energy budget drawn from your own sleep, heart rate and activity. See how much you have before you spend it.

Pace your day

Plan gentle activity that stays inside your limits, with early warnings before you push past your threshold into a crash.

Built on your data

A model trained on you, not population averages, learns your personal patterns and gets more useful the more you use it.
