# Zeno PDF vs PDF Reader

The clearest difference is ads: Zeno PDF at none against PDF Reader's shown. Zeno PDF also leads on review sentiment (84% vs 61%) and monetization model (free vs ad-supported). PDF Reader's advantage is update cadence (weekly vs every 4 weeks) and ratings volume (3.2K vs 622). On price, rating, in-app purchases and device support there is nothing between them.

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

On the App Store both sit at effectively the same score — 4.7 for Zeno PDF against 4.8 for PDF Reader. That said, the two scores are not equally well evidenced: PDF Reader has 3.2K ratings behind it against 622, so its average is the more settled of the two. Written reviews are what separate them: 84% of Zeno PDF's written reviews are positive against 61% of PDF Reader's.

Zeno PDF ships an update every 4 weeks, PDF Reader weekly. Both last shipped on September 22, 2026.
