# PDF Reader vs Smart Cleaner

The clearest difference is rating: PDF Reader at 5.0 against Smart Cleaner's 3.7. Smart Cleaner's advantage is ads (none vs shown) and ratings volume (15 vs 2). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. PDF Reader sells 3 in-app purchases, starting at $14.99 per 7 days and Smart Cleaner sells 3 in-app purchases, starting at $9.99 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 3.7. That said, the two scores are not equally well evidenced: Smart Cleaner has 15 ratings behind it against 2, so its average is the more settled of the two.

PDF Reader ships an update every 9 days, Smart Cleaner every 8 days. The most recent releases landed on November 5, 2026 and November 6, 2026 respectively.
