# Whistle vs Weighback

The clearest difference is rating: Weighback at 5.0 against Whistle's 4.3. Whistle's advantage is ratings volume (11 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Whistle sells 5 in-app purchases, starting at $4.99 per month and Weighback sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Weighback holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Whistle has 11 ratings behind it against 1, so its average is the more settled of the two.

Whistle ships an update monthly, Weighback every 3 weeks. Both last shipped on November 5, 2026.
