Verdict

The call

The clearest difference is price: Text to Speech PDF Reader at Free against Text to Speech Pro's $9.99. Text to Speech PDF Reader also leads on rating (4.5 vs 3.8) and ratings volume (560 vs 33). Text to Speech Pro's advantage is in-app purchases (none vs 10) and review sentiment (55% vs 46%). On ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Text to Speech PDF Reader holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: Text to Speech PDF Reader has 560 ratings behind it against 33, so its average is the more settled of the two. Written reviews complicate that: 55% of Text to Speech Pro's written reviews are positive against 46% of Text to Speech PDF Reader's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Text to Speech Pro ships an update every 3 weeks, Text to Speech PDF Reader every 10 days. The most recent releases landed on October 18, 2026 and October 21, 2026 respectively.
