# SFEROOM vs Audio Mastering

The clearest difference is rating: Audio Mastering at 4.6 against SFEROOM's 4.1. Audio Mastering also leads on ratings volume (143 vs 11). SFEROOM's advantage is in-app purchases (none vs 6) and review sentiment (57% vs 23%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Audio Mastering sells 6 in-app purchases, starting at $9.99 per 7 days. SFEROOM asks for nothing beyond the download.

Audio Mastering holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: Audio Mastering has 143 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 57% of SFEROOM's written reviews are positive against 23% of Audio Mastering's, so the app with the better star average is not the one people write more warmly about.

SFEROOM ships an update monthly, Audio Mastering fortnightly. The most recent releases landed on October 19, 2026 and October 21, 2026 respectively.
