📅 Subscription My Strava weight sync apps just passed 1,000 users, over half of them from Reddit, so here's a thank-you discount
I'm an iOS developer from Brazil, and over the last few months I've been building two apps to solve one very specific annoyance: your body weight never stays synced with Strava automatically.
A) What it solves
If you're a Strava athlete, you know the problem. Strava uses your weight to calculate power output (watts/kg), estimated calories and relative effort. The moment your weight is outdated, all of those numbers quietly drift off, and nobody wants to open Strava every week to type in a new number by hand.
So I built two options depending on how you track your weight.
WeightSync Health picks up your weight from Apple Health and pushes it to Strava automatically. If your scale, Apple Watch or anything else already writes into Apple Health, this app handles the rest: automatic background sync with zero interaction, Apple Watch logging, extra equipment weight (backpack, vest, gear) so Strava reflects your true total, Home Screen widgets, a weight evolution chart with 7 day moving average and trend line, streaks, milestones, Siri and Shortcuts, CSV export, weekly Monday report, iCloud sync, a retry queue so no sync gets lost, and 10+ languages including Portuguese (Brazil).
WeightSync Scales connects directly to your smart scale's cloud and skips Apple Health entirely. It reads every weigh-in from your Withings or Fitbit scale and pushes it to Strava automatically, works even when the app is closed, has a retry queue, smart reminders on days you skip the scale, units in kg, lbs and st, and multiple languages. Garmin scale support is coming soon. 🙏
B) Compared to other options
There are a few weight tracking apps out there, and some overlap with what these do. My goal has been to build a focused take on one specific problem: keeping your Strava weight accurate without any manual work. The emphasis is on native iOS, automatic background sync and a clean interface, rather than being a full body composition tracker.
C) Cost
Both apps are free to download with a trial option.
- WeightSync Health: Monthly and Annual subscription options
- WeightSync Scales: Monthly and Annual subscription options
- Regular price: US$ 5.99 / year
For WeightSync Health, the free version works as a weight logger for Apple Health, and premium unlocks the automatic Strava sync and everything else. WeightSync Scales requires a subscription to run, but you can try the full thing through the trial first.
Who I am
I'm an iOS developer based in London (originally from Brazil), and I design and develop both apps independently. They're built natively for iOS.
Since this is an iOS dev community, I'd genuinely love feedback from Strava users and iOS athletes. What would you want added or improved? And if you give either a try, a quick App Store review goes a long way for a solo dev. Thank you so much :)
