Verdict

The call

The clearest difference is ratings volume: AudioKit Synth One Synthesizer at 27K against Polygonome's 8. AudioKit Synth One Synthesizer also leads on update cadence (monthly vs every 4 months). Polygonome's advantage is iOS requirement (10.3 vs 13.0). On price, rating, review sentiment and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

AudioKit Synth One Synthesizer holds the better App Store score, 4.9 against 4.8. That said, the two scores are not equally well evidenced: AudioKit Synth One Synthesizer has 27K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 100% of Polygonome's written reviews are positive against 95% of AudioKit Synth One Synthesizer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Polygonome ships an update every 4 months, AudioKit Synth One Synthesizer monthly. The most recent releases landed on November 6, 2026 and November 12, 2026 respectively.
