# Henle Library vs 国际声乐

The clearest difference is rating: Henle Library at 3.0 against 国际声乐's 1.0. Henle Library also leads on ratings volume (94 vs 2). 国际声乐's advantage is update cadence (monthly vs every 3 months). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Henle Library sells 8 one-off in-app purchases and 国际声乐 sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Henle Library holds the better App Store score, 3.0 against 1.0. That said, the two scores are not equally well evidenced: Henle Library has 94 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 35% of Henle Library's written reviews are positive against 30% of 国际声乐's.

Henle Library ships an update every 3 months, 国际声乐 monthly. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
