# Core Synth Free vs 简谱学钢琴

The clearest difference is rating: 简谱学钢琴 at 5.0 against Core Synth Free's 2.9. 简谱学钢琴 also leads on update cadence (every 2 months vs every 13 months). Core Synth Free's advantage is ads (none vs shown) and ratings volume (8 vs 2). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Core Synth Free sells 1 one-off in-app purchase and 简谱学钢琴 sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

简谱学钢琴 holds the better App Store score, 5.0 against 2.9. Both are backed by a comparable volume of ratings — 8 and 2 respectively. Written reviews complicate that: 64% of Core Synth Free's written reviews are positive against 59% of 简谱学钢琴's, so the app with the better star average is not the one people write more warmly about.

Core Synth Free ships an update every 13 months, 简谱学钢琴 every 2 months. The most recent releases landed on October 20, 2026 and October 25, 2026 respectively.
