# Voice Synth vs Matrix Vocoder

The clearest difference is update cadence: Voice Synth at every 6 weeks against Matrix Vocoder's every 15 months. Voice Synth also leads on review sentiment (62% vs 42%) and ratings volume (333 vs 20). Matrix Vocoder's advantage is rating (4.3 vs 4.1) and price ($5.99 vs $8.99). On ads, in-app purchases, monetization model and device support there is nothing between them.

Voice Synth costs $8.99 and Matrix Vocoder $5.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Matrix Vocoder holds the better App Store score, 4.3 against 4.1. That said, the two scores are not equally well evidenced: Voice Synth has 333 ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 62% of Voice Synth's written reviews are positive against 42% of Matrix Vocoder's, so the app with the better star average is not the one people write more warmly about.

Voice Synth ships an update every 6 weeks, Matrix Vocoder every 15 months. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
