# SmarterNoise vs SoundClass

The clearest difference is update cadence: SoundClass at every 10 days against SmarterNoise's every 6 weeks. SmarterNoise's advantage is rating (4.6 vs 4.4) and ratings volume (115 vs 10). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. SmarterNoise sells 2 one-off in-app purchases and SoundClass sells 7 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

SmarterNoise holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: SmarterNoise has 115 ratings behind it against 10, so its average is the more settled of the two.

SmarterNoise ships an update every 6 weeks, SoundClass every 10 days. Both last shipped on October 6, 2026.
