# SpaceSweep vs PDF Reader

The clearest difference is rating: PDF Reader at 5.0 against SpaceSweep's 4.5. PDF Reader also leads on update cadence (every 3 weeks vs every 2 months). SpaceSweep's advantage is ads (none vs shown) and ratings volume (356 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. SpaceSweep sells 5 in-app purchases, starting at $4.99 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 4.5. That said, the two scores are not equally well evidenced: SpaceSweep has 356 ratings behind it against 1, so its average is the more settled of the two.

SpaceSweep ships an update every 2 months, PDF Reader every 3 weeks. The most recent releases landed on October 24, 2026 and September 24, 2026 respectively.
