# SVS vs AVR Controller

The clearest difference is review sentiment: AVR Controller at 100% against SVS's 68%. AVR Controller also leads on update cadence (monthly vs every 2 months). SVS's advantage is rating (4.2 vs 3.9) and ratings volume (95 vs 20). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

SVS holds the better App Store score, 4.2 against 3.9. Both are backed by a comparable volume of ratings — 95 and 20 respectively. Written reviews complicate that: 68% of SVS's written reviews are positive against 100% of AVR Controller's, so the app with the better star average is not the one people write more warmly about.

SVS ships an update every 2 months, AVR Controller monthly. The most recent releases landed on September 15, 2026 and September 30, 2026 respectively.
