# Noise Meter vs Speed Maths SSC

The clearest difference is iOS requirement: Speed Maths SSC at 15.0 against Noise Meter's 17.6. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Noise Meter sells 9 in-app purchases, starting at $5.99 per 7 days and Speed Maths SSC sells 2 in-app purchases, starting at $0.99 per year. Whichever you choose, the download price is not the number that matters.
