# CPU vs PDF Toolkit

The clearest difference is rating: CPU at 5.0 against PDF Toolkit's 4.4. PDF Toolkit's advantage is in-app purchases (none vs 4) and ratings volume (20 vs 3). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. CPU sells 4 in-app purchases, starting at $6.99 per 7 days. PDF Toolkit asks for nothing beyond the download.

CPU holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: PDF Toolkit has 20 ratings behind it against 3, so its average is the more settled of the two.

CPU ships an update fortnightly, PDF Toolkit every 9 days. The most recent releases landed on October 24, 2026 and October 28, 2026 respectively.
