Keep your Strava weight up to date without thinking about it. WeightSync reads your weight from Apple Health and sends it to Strava, so your W/kg, power estimates and calorie numbers stay accurate with no manual entry. HOW IT WORKS Connect Apple Health and Strava once. Then weigh yourself as usual: on a smart scale, in its own app, on your iPhone or on Apple Watch. WeightSync detects the new entry and syncs it in the background, even when the app is closed. WHY IT MATTERS Strava uses your weight to estimate power, calories and power to weight ratio. If the number in your profile is months old, so are those metrics. Built for cyclists watching their W/kg, runners managing race weight and triathletes who want metrics they can trust.
