ByStep

ByStep is the app where you challenge your friends with fitness. This connector links Claude to your own ByStep account, so you can plan training, keep your strength log and track your body from a chat.

What Claude can do:

• List your strength routines with their exercises, sets and reps.
• Search the ByStep exercise list, including exercises you created.
• Create a routine, rename it, or replace its exercises.
• Read your strength log: sessions, sets, weights and the best set of an exercise.
• Add strength sessions and sets that you tell it about. Change or delete only the sets and sessions it added.
• List your body measurements: weight, body fat and body sizes such as waist, chest and arms.
• Add a measurement, change one, or delete one. Claude asks before each change that replaces or deletes data.

New and changed routines and sessions appear in the ByStep app on its next sync. A session added here never counts as a workout and never earns points in your challenges.

What Claude cannot do:

• It sees workouts only when you typed them by hand in ByStep and they have no sets yet, as a day, a start time and a length.
• It cannot read workouts, steps, heart rate, calories or body weight from Apple Health, Health Connect or a watch. It receives no Apple Health or Health Connect data.
• It cannot read your points, challenges, friends, other members or progress photos.
• It cannot delete a routine, a workout, or anything you logged in the ByStep app.

Before you connect: you need a ByStep account with a verified email. Sign in on bystep.fit and press Allow on the consent page. The page lists each permission. Disconnect at any time in ByStep Settings > Connected apps, or remove the connector in Claude.

ByStep is not a medical device. Measurements and logs are the numbers you enter. They are not medical advice.
