# PDF Max vs PDF Cabinet

The clearest difference is rating: PDF Max at 4.5 against PDF Cabinet's 3.8. PDF Max also leads on ratings volume (1.2K vs 57). PDF Cabinet's advantage is in-app purchases (none vs 10) and review sentiment (66% vs 35%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. PDF Max sells 10 in-app purchases, starting at $1.99 per 7 days. PDF Cabinet asks for nothing beyond the download.

PDF Max holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: PDF Max has 1.2K ratings behind it against 57, so its average is the more settled of the two. Written reviews complicate that: 35% of PDF Max's written reviews are positive against 66% of PDF Cabinet's, so the app with the better star average is not the one people write more warmly about.

PDF Max ships an update monthly, PDF Cabinet every 5 weeks. The most recent releases landed on November 6, 2026 and November 1, 2026 respectively.
