Both are free to download. Soniox sells 2 in-app purchases, starting at $19.99 per month and LecSync sells 4 in-app purchases, starting at $39.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Soniox holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Soniox has 169 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 68% of Soniox's written reviews are positive against 71% of LecSync's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Soniox ships an update every 10 days, LecSync every 9 days. The most recent releases landed on October 2, 2026 and September 30, 2026 respectively.
