Move in a way that fits your body.
Log a gym session, a walk or a gentle stretch. Leo keeps your workouts next to your sleep, symptoms and medications, so you can see how they sit together.

Log the session, your way.
On Apple Watch you can run a live workout with heart rate, calories and distance on your wrist. The finished workout lands back on your phone.
- Sets, reps, weight and effort, with supersets, drop sets and pyramids
- Estimated one-rep max and a plate calculator
- Over 60 activity types, from lifting to yoga, walking and swimming
- Reusable workout templates and saved routes

One number, compared only with you.
Each morning Leo shows a readiness number from 0 to 100. It describes how today's signals compare with your usual. It isn't a medical assessment, and what you do with it is up to you.
- Uses overnight HRV, sleep, resting heart rate, yesterday's training and breathing rate
- Worked out on your phone from your own Apple Health data
- Compared with your own recent baseline, never with other people
- Uses whichever of those signals your devices recorded that day

Movement, logged with everything else.
Some condition hubs have their own movement tools, like activity and spoons for ME/CFS pacing, or pain logs you can look at next to your workouts.

What readiness is not
Readiness reflects patterns in your own recovery signals. It doesn't diagnose, screen for or treat anything, and Leo won't tell you whether to train.
