# AcoustiTools® vs Noise Guru

The clearest difference is price: Noise Guru at Free against AcoustiTools®'s $39.99. Noise Guru also leads on in-app purchases (none vs 2) and ratings volume (360 vs 7). AcoustiTools®'s advantage is review sentiment (100% vs 88%). On rating, update cadence, ads and device support there is nothing between them.

Noise Guru is free to download; AcoustiTools® costs $39.99 up front. AcoustiTools® sells 2 one-off in-app purchases. Noise Guru asks for nothing beyond the download.

Noise Guru holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Noise Guru has 360 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 100% of AcoustiTools®'s written reviews are positive against 88% of Noise Guru's, so the app with the better star average is not the one people write more warmly about.

AcoustiTools® ships an update every 2 months, Noise Guru monthly. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
