# Whistle vs sleepfuzz

The clearest difference is rating: sleepfuzz at 5.0 against Whistle's 4.3. sleepfuzz also leads on monetization model (free vs free with in-app purchases). Whistle's advantage is ratings volume (11 vs 2) and device support. On price, in-app purchases and iOS requirement there is nothing between them.

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

sleepfuzz 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 2, so its average is the more settled of the two.
