# SmarterNoise vs Decibel Pro

The clearest difference is in-app purchases: Decibel Pro at none against SmarterNoise's 2. Decibel Pro also leads on ads (none vs shown) and review sentiment (83% vs 75%). SmarterNoise's advantage is rating (4.6 vs 4.4) and iOS requirement (12.0 vs 16.1). On price, ratings volume and device support there is nothing between them.

Both are free to download. SmarterNoise sells 2 one-off in-app purchases. Decibel Pro asks for nothing beyond the download.

SmarterNoise holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 117 and 75 respectively. Written reviews complicate that: 75% of SmarterNoise's written reviews are positive against 83% of Decibel Pro's, so the app with the better star average is not the one people write more warmly about.
