# Voice Synth Modular vs Otamatone Studio

The clearest difference is update cadence: Otamatone Studio at every 6 days against Voice Synth Modular's monthly. Otamatone Studio also leads on iOS requirement (11.0 vs 16.6). Voice Synth Modular's advantage is ratings volume (3K vs 49) and rating (4.2 vs 3.9). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Voice Synth Modular sells 2 one-off in-app purchases and Otamatone Studio sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Voice Synth Modular holds the better App Store score, 4.2 against 3.9. That said, the two scores are not equally well evidenced: Voice Synth Modular has 3K ratings behind it against 49, so its average is the more settled of the two. Written reviews complicate that: 41% of Voice Synth Modular's written reviews are positive against 46% of Otamatone Studio's, so the app with the better star average is not the one people write more warmly about.

Voice Synth Modular ships an update monthly, Otamatone Studio every 6 days. Both last shipped on October 17, 2026.
