# PDF Reader vs LensDoc

The clearest difference is update cadence: LensDoc at daily against PDF Reader's every 10 days. PDF Reader's advantage is ratings volume (492 vs 4) and rating (4.3 vs 4.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. PDF Reader sells 2 in-app purchases, starting at $5.99 per 7 days and LensDoc sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

PDF Reader holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: PDF Reader has 492 ratings behind it against 4, so its average is the more settled of the two.

PDF Reader ships an update every 10 days, LensDoc daily. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
