# Decibels vs Specguy

The clearest difference is iOS requirement: Specguy at 15.1 against Decibels's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Decibels sells 1 in-app purchase, starting at $3.99 per month and Specguy sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
