# InstaPDF vs Revu AI Reply

The clearest difference is ads: InstaPDF at none against Revu AI Reply's shown. InstaPDF also leads on ratings volume (1.1K vs 6). Revu AI Reply's advantage is update cadence (every 4 days vs fortnightly) and review sentiment (100% vs 85%). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. InstaPDF sells 2 in-app purchases, starting at $2.99 per month and Revu AI Reply sells 9 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for InstaPDF against 5.0 for Revu AI Reply. That said, the two scores are not equally well evidenced: InstaPDF has 1.1K ratings behind it against 6, so its average is the more settled of the two. Written reviews are what separate them: 85% of InstaPDF's written reviews are positive against 100% of Revu AI Reply's.

InstaPDF ships an update fortnightly, Revu AI Reply every 4 days. The most recent releases landed on October 23, 2026 and October 17, 2026 respectively.
