# A/B Audio vs SonoBus

The clearest difference is price: SonoBus at Free against A/B Audio's $3.99. SonoBus also leads on rating (4.5 vs 4.3) and ratings volume (41 vs 7). A/B Audio's advantage is review sentiment (87% vs 68%). On update cadence, ads, in-app purchases and device support there is nothing between them.

SonoBus is free to download; A/B Audio costs $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

SonoBus holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: SonoBus has 41 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 87% of A/B Audio's written reviews are positive against 68% of SonoBus's, so the app with the better star average is not the one people write more warmly about.

A/B Audio ships an update every 2 months, SonoBus every 6 weeks. The most recent releases landed on October 5, 2026 and October 14, 2026 respectively.
