# AI QR Code Scan vs PDF Reader

The clearest difference is rating: PDF Reader at 4.4 against AI QR Code Scan's 3.7. PDF Reader also leads on review sentiment (42% vs 0%) and ratings volume (316 vs 12). AI QR Code Scan's advantage is ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. AI QR Code Scan sells 3 in-app purchases, starting at $8.99 per 7 days and PDF Reader sells 2 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PDF Reader holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: PDF Reader has 316 ratings behind it against 12, so its average is the more settled of the two.
