# Sonic Master vs aiSpeech

The clearest difference is ads: aiSpeech at none against Sonic Master's shown. aiSpeech also leads on update cadence (every 2 weeks vs every 4 months) and ratings volume (260 vs 46). Sonic Master's advantage is review sentiment (83% vs 61%) and iOS requirement (12.0 vs 15.0). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sonic Master sells 2 one-off in-app purchases and aiSpeech sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Sonic Master against 4.6 for aiSpeech. That said, the two scores are not equally well evidenced: aiSpeech has 260 ratings behind it against 46, so its average is the more settled of the two. Written reviews are what separate them: 83% of Sonic Master's written reviews are positive against 61% of aiSpeech's.

Sonic Master ships an update every 4 months, aiSpeech every 2 weeks. The most recent releases landed on September 14, 2026 and September 9, 2026 respectively.
