# PDF AI vs PDF Scanner

The clearest difference is ratings volume: PDF AI at 151 against PDF Scanner's 2. PDF AI also leads on iOS requirement (15.0 vs 18.0). PDF Scanner's advantage is rating (5.0 vs 4.8). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. PDF AI sells 5 in-app purchases, starting at $7.99 per 7 days and PDF Scanner sells 4 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PDF Scanner holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: PDF AI has 151 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 90% and 90% positive.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 20, 2026 and September 13, 2026 respectively.
