# Spamdrain vs PDF Scanner

The clearest difference is rating: PDF Scanner at 5.0 against Spamdrain's 4.4. PDF Scanner also leads on update cadence (every 3 days vs every 2 months). Spamdrain's advantage is ratings volume (1.2K vs 5) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Spamdrain sells 12 one-off in-app purchases and PDF Scanner sells 8 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PDF Scanner holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Spamdrain has 1.2K ratings behind it against 5, so its average is the more settled of the two.

Spamdrain ships an update every 2 months, PDF Scanner every 3 days. The most recent releases landed on October 14, 2026 and October 15, 2026 respectively.
