# SymphonyLight vs YS Audio

The clearest difference is rating: YS Audio at 3.5 against SymphonyLight's 2.2. SymphonyLight's advantage is update cadence (monthly vs every 45 months) and review sentiment (23% vs 0%). 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.

YS Audio holds the better App Store score, 3.5 against 2.2. That said, the two scores are not equally well evidenced: SymphonyLight has 106 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 23% of SymphonyLight's written reviews are positive against 0% of YS Audio's, so the app with the better star average is not the one people write more warmly about.

SymphonyLight ships an update monthly, YS Audio every 45 months. The most recent releases landed on October 13, 2026 and October 5, 2026 respectively.
