# Voice Synth Modular vs Synth Pro

The clearest difference is ads: Voice Synth Modular at none against Synth Pro's shown. Voice Synth Modular also leads on ratings volume (3.1K vs 555) and iOS requirement (16.6 vs 18.0). Synth Pro's advantage is review sentiment (71% vs 41%) and rating (4.6 vs 4.2). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Voice Synth Modular sells 2 one-off in-app purchases and Synth Pro sells 20 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

Synth Pro holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Voice Synth Modular has 3.1K ratings behind it against 555, so its average is the more settled of the two. Written reviews point the same way: 41% of Voice Synth Modular's written reviews are positive against 71% of Synth Pro's.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
