Verdict
The clearest difference is rating: Text to Speech PDF Reader at 4.5 against ChmPlus Lite's 3.6. Text to Speech PDF Reader also leads on ads (none vs shown) and ratings volume (552 vs 11). ChmPlus Lite's advantage is in-app purchases (none vs 10) and iOS requirement (11.0 vs 16.0). On price, review sentiment and device support there is nothing between them.

Both are free to download. Text to Speech PDF Reader sells 10 in-app purchases, starting at $0.99 per 7 days. ChmPlus Lite asks for nothing beyond the download.
Text to Speech PDF Reader holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: Text to Speech PDF Reader has 552 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 49% of ChmPlus Lite's written reviews are positive against 44% of Text to Speech PDF Reader's, so the app with the better star average is not the one people write more warmly about.
ChmPlus Lite ships an update monthly, Text to Speech PDF Reader every 10 days. The most recent releases landed on August 30, 2026 and September 23, 2026 respectively.
