# Decibel Meter™ vs Q Booster

The clearest difference is iOS requirement: Q Booster at 15.0 against Decibel Meter™'s 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Decibel Meter™ sells 3 in-app purchases, starting at $0.99 per 7 days and Q Booster sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
