Verdict

The call

ReceptionRating · Positive reviews · Number of ratings

电子钢琴 holds the better App Store score, 5.0 against 2.9. That said, the two scores are not equally well evidenced: Core Synth Free has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 57% of Core Synth Free's written reviews are positive against 0% of 电子钢琴's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Core Synth Free ships an update every 13 months, 电子钢琴 every 2 months. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
