# Core Synth Free vs SynthMaster Player

The clearest difference is rating: SynthMaster Player at 4.4 against Core Synth Free's 2.9. SynthMaster Player also leads on update cadence (every 3 months vs every 13 months) and ratings volume (55 vs 8). Core Synth Free's advantage is review sentiment (64% vs 52%) and iOS requirement (8.0 vs 11.0). On price, ads, 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 SynthMaster Player sells 13 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

SynthMaster Player holds the better App Store score, 4.4 against 2.9. That said, the two scores are not equally well evidenced: SynthMaster Player has 55 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 64% of Core Synth Free's written reviews are positive against 52% of SynthMaster Player'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, SynthMaster Player every 3 months. The most recent releases landed on June 8, 2026 and September 24, 2026 respectively.
