Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
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.
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.
