# SmarterNoise Pro vs SpectraMania

The clearest difference is review sentiment: SpectraMania at 75% against SmarterNoise Pro's 29%. SpectraMania also leads on in-app purchases (none vs 4). SmarterNoise Pro's advantage is price (Free vs $7.99) and rating (4.4 vs 4.0). On ads and device support there is nothing between them.

SmarterNoise Pro is free to download; SpectraMania costs $7.99 up front. SmarterNoise Pro sells 4 one-off in-app purchases. SpectraMania asks for nothing beyond the download.

SmarterNoise Pro holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: SmarterNoise Pro has 31 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 29% of SmarterNoise Pro's written reviews are positive against 75% of SpectraMania's, so the app with the better star average is not the one people write more warmly about.

SmarterNoise Pro ships an update monthly, SpectraMania every 6 months. The most recent releases landed on September 22, 2026 and October 17, 2026 respectively.
