# Right PDF Reader vs PDF Reader Pro

The clearest difference is rating: Right PDF Reader at 4.6 against PDF Reader Pro's 3.6. Right PDF Reader also leads on ads (none vs shown) and monetization model (free vs ad-supported). PDF Reader Pro's advantage is update cadence (every 4 months vs every 11 months). On price, review sentiment, ratings volume 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.

Right PDF Reader holds the better App Store score, 4.6 against 3.6. Both are backed by a comparable volume of ratings — 5 and 8 respectively. Written reviews complicate that: 92% of Right PDF Reader's written reviews are positive against 100% of PDF Reader Pro's, so the app with the better star average is not the one people write more warmly about.

Right PDF Reader ships an update every 11 months, PDF Reader Pro every 4 months. The most recent releases landed on September 27, 2026 and September 28, 2026 respectively.
