# Modules vs SmarterNoise Pro

The clearest difference is rating: SmarterNoise Pro at 4.4 against Modules's 4.0. Modules's advantage is review sentiment (45% vs 29%) and iOS requirement (9.0 vs 12.0). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Modules sells 1 one-off in-app purchase and SmarterNoise Pro sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

SmarterNoise Pro holds the better App Store score, 4.4 against 4.0. Both are backed by a comparable volume of ratings — 17 and 31 respectively. Written reviews complicate that: 45% of Modules's written reviews are positive against 29% of SmarterNoise Pro's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on September 2, 2026 and September 7, 2026 respectively.
