# Core Synth Free vs 电子钢琴

The clearest difference is review sentiment: Core Synth Free at 57% against 电子钢琴's 0%. Core Synth Free also leads on ads (none vs shown) and ratings volume (8 vs 1). 电子钢琴's advantage is rating (5.0 vs 2.9) and update cadence (every 2 months vs every 13 months). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Core Synth Free sells 1 one-off in-app purchase and 电子钢琴 sells 4 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

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.

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.
