# AcousticLab vs Sidus Audio

The clearest difference is in-app purchases: Sidus Audio at none against AcousticLab's 1. Sidus Audio also leads on rating (4.4 vs 4.0) and update cadence (every 6 weeks vs every 7 months). AcousticLab's advantage is review sentiment (100% vs 71%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. AcousticLab sells 1 in-app purchase, starting at $9.99 per month. Sidus Audio asks for nothing beyond the download.

Sidus Audio holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Sidus Audio has 17 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of AcousticLab's written reviews are positive against 71% of Sidus Audio's, so the app with the better star average is not the one people write more warmly about.

AcousticLab ships an update every 7 months, Sidus Audio every 6 weeks. The most recent releases landed on October 10, 2026 and October 24, 2026 respectively.
