Verdict
The clearest difference is review sentiment: SemanTer at 50% against ChatPDF's 0%. SemanTer also leads on ads (none vs shown) and device support (3 vs 1). ChatPDF's advantage is rating (4.2 vs 3.1). On price, ratings volume, update cadence and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. SemanTer sells 7 in-app purchases, starting at $1.49 per 7 days and ChatPDF sells 2 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
ChatPDF holds the better App Store score, 4.2 against 3.1. Both are backed by a comparable volume of ratings — 9 and 5 respectively. Written reviews complicate that: 50% of SemanTer's written reviews are positive against 0% of ChatPDF's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 24, 2026 and October 30, 2026 respectively.
