# WeightSyncr vs Scale Relay

The clearest difference is rating: Scale Relay at 5.0 against WeightSyncr's 4.5. Scale Relay also leads on update cadence (every 10 days vs every 2 months). WeightSyncr's advantage is ratings volume (15 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. WeightSyncr sells 2 in-app purchases, starting at $0.99 per month and Scale Relay sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Scale Relay holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: WeightSyncr has 15 ratings behind it against 1, so its average is the more settled of the two.

WeightSyncr ships an update every 2 months, Scale Relay every 10 days. The most recent releases landed on November 4, 2026 and November 9, 2026 respectively.
