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.

Verdict
The clearest difference is price: WeightSync at Free against LapTrak's $2.99. WeightSync also leads on rating (5.0 vs 2.4) and update cadence (every 5 days vs monthly). LapTrak's advantage is review sentiment (40% vs 0%) and ratings volume (5 vs 1). On ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
WeightSync is free to download; LapTrak costs $2.99 up front. LapTrak sells 8 one-off in-app purchases and WeightSync sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
WeightSync holds the better App Store score, 5.0 against 2.4. That said, the two scores are not equally well evidenced: LapTrak has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 40% of LapTrak's written reviews are positive against 0% of WeightSync's, so the app with the better star average is not the one people write more warmly about.
LapTrak ships an update monthly, WeightSync every 5 days. The most recent releases landed on November 7, 2026 and October 31, 2026 respectively.
