# 音书 vs TouchSounds

The clearest difference is review sentiment: 音书 at 100% against TouchSounds's 50%. 音书 also leads on in-app purchases (none vs 2). TouchSounds's advantage is rating (5.0 vs 4.5) and ads (none vs shown). On price, ratings volume, update cadence and monetization model there is nothing between them.

Both are free to download. TouchSounds sells 2 one-off in-app purchases. 音书 asks for nothing beyond the download.

TouchSounds holds the better App Store score, 5.0 against 4.5. Both are backed by a comparable volume of ratings — 8 and 3 respectively. Written reviews complicate that: 100% of 音书's written reviews are positive against 50% of TouchSounds's, so the app with the better star average is not the one people write more warmly about.

音书 ships an update every 3 weeks, TouchSounds every 11 days. The most recent releases landed on October 29, 2026 and October 2, 2026 respectively.
