Verdict

The call

AI Clean and PDF Reader both sit at 4.5 stars, but that hides the real split: 75% of PDF Reader's written reviews are positive against 62% of AI Clean's. PDF Reader also leads on chart position (#190 vs unranked). AI Clean's advantage is ratings volume (1.2K vs 134). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. AI Clean sells 9 in-app purchases, starting at $5.99 per 7 days and PDF Reader sells 2 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

AI Clean holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: AI Clean has 1.2K ratings behind it against 134, so its average is the more settled of the two. Written reviews complicate that: 62% of AI Clean's written reviews are positive against 75% of PDF Reader's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

AI Clean ships an update every 2 weeks, PDF Reader every 3 weeks. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
