In your coach

Your day, turned into what to do about it.

Lowdown reads your sleep, heart rate, steps and workouts from Apple Health — then talks you through them and ties them to your training and food. Here's what that looks like in the app.

Morning. You slept 7h 12m and your resting HR's down to 52 — you're well recovered. Light day so far, so there's room for a harder session.

what should I train?

Push legs or a longer zone-2. Your sleep and heart rate both say you've got the headroom for it. Want me to plan it?

⌚

Connects your data

Pulls sleep, heart rate and activity from Apple Health automatically — including the detail your watch app hides.

“Logged a burger and fries.” “How’s my recovery?” Chat-first, so logging takes seconds and answers are plain-English.
