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. FEATURES • Automatic background sync from Apple Health to Strava • Retry queue and full sync history • Apple Watch app with complications and Digital Crown input • Home Screen widgets and Live Activity • Weigh in streaks and milestones to keep you consistent • Siri and Shortcuts: log your weight or force a sync by voice • Extra weight profiles to add gear or equipment to the synced value • Smart reminders that skip themselves when you have already weighed in PREMIUM • Weight chart with 7 day moving average and trend line • Weekly report every Monday • CSV export of your full history • iCloud sync across your devices • Multiple named extra weight profiles FREE VERSION • Read your weight from Apple Health • Manual weight entry • Save weight back to Apple Health • Log from Apple Watch Strava sync and Premium features are part of the subscription, which starts with a free trial. PRIVACY Your weight travels only between Apple Health and Strava. No extra account needed. GOOD TO KNOW The Strava API records weight on the day it is sent, not on the original entry date. This is a Strava platform limitation. REQUIREMENTS iPhone with iOS 16.6 or later. The Apple Watch app requires watchOS 11.6 or later. A Strava account is required.
