# ARTERNAL Mobile vs PDF Master

The clearest difference is rating: PDF Master at 5.0 against ARTERNAL Mobile's 4.5. ARTERNAL Mobile's advantage is in-app purchases (none vs 6) and update cadence (every 10 days vs every 15 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. PDF Master sells 6 in-app purchases, starting at $0.99 per 7 days. ARTERNAL Mobile asks for nothing beyond the download.
