# Autodesk Vault Mobile vs PDF Reader Pro

The clearest difference is rating: Autodesk Vault Mobile at 4.4 against PDF Reader Pro's 3.6. Autodesk Vault Mobile also leads on ads (none vs shown) and monetization model (free vs ad-supported). PDF Reader Pro's advantage is review sentiment (67% vs 40%) and iOS requirement (13.0 vs 17.4). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Autodesk Vault Mobile holds the better App Store score, 4.4 against 3.6. Both are backed by a comparable volume of ratings — 12 and 8 respectively. Written reviews complicate that: 40% of Autodesk Vault Mobile's written reviews are positive against 67% of PDF Reader Pro's, so the app with the better star average is not the one people write more warmly about.

Autodesk Vault Mobile ships an update every 3 months, PDF Reader Pro every 4 months. The most recent releases landed on October 31, 2026 and November 3, 2026 respectively.
