# Hotmoon vs Pink Noise Generator

The clearest difference is rating: Pink Noise Generator at 4.7 against Hotmoon's 3.2. Pink Noise Generator also leads on review sentiment (50% vs 23%) and ratings volume (707 vs 42). Hotmoon's advantage is update cadence (fortnightly vs every 4 months) and monetization model (free vs free with in-app purchases). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Hotmoon sells 2 in-app purchases, starting at $4.99 per month and Pink Noise Generator sells 4 in-app purchases, starting at $24.99 per year. Whichever you choose, the download price is not the number that matters.

Pink Noise Generator holds the better App Store score, 4.7 against 3.2. That said, the two scores are not equally well evidenced: Pink Noise Generator has 707 ratings behind it against 42, so its average is the more settled of the two.
