# Pearl Diver HD vs Classify It!

The clearest difference is rating: Classify It! at 4.0 against Pearl Diver HD's 1.5. Classify It! also leads on ratings volume (64 vs 2) and iOS requirement (6.0 vs 17.6). Pearl Diver HD's advantage is review sentiment (71% vs 55%). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Classify It! holds the better App Store score, 4.0 against 1.5. That said, the two scores are not equally well evidenced: Classify It! has 64 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 71% of Pearl Diver HD's written reviews are positive against 55% of Classify It!'s, so the app with the better star average is not the one people write more warmly about.
