# ZCleaner vs PDF Reader

The clearest difference is rating: PDF Reader at 5.0 against ZCleaner's 4.1. ZCleaner's advantage is ratings volume (21 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. ZCleaner sells 6 in-app purchases, starting at $6.99 per 7 days and PDF Reader sells 2 in-app purchases, starting at $19.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PDF Reader holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: ZCleaner has 21 ratings behind it against 1, so its average is the more settled of the two.

ZCleaner ships an update monthly, PDF Reader every 3 weeks. The most recent releases landed on October 24, 2026 and September 24, 2026 respectively.
