# Soniox vs Sinaps AI

The clearest difference is in-app purchases: Sinaps AI at none against Soniox's 2. Sinaps AI also leads on review sentiment (88% vs 68%). Soniox's advantage is rating (4.7 vs 4.4) and ratings volume (228 vs 8). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Soniox sells 2 in-app purchases, starting at $19.99 per month. Sinaps AI asks for nothing beyond the download.

Soniox holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Soniox has 228 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 68% of Soniox's written reviews are positive against 88% of Sinaps AI's, so the app with the better star average is not the one people write more warmly about.

Soniox ships an update every 10 days, Sinaps AI weekly. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
