# Rock Identifier vs Gem Identifier

The clearest difference is rating: Gem Identifier at 5.0 against Rock Identifier's 4.5. Rock Identifier's advantage is ratings volume (234 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Rock Identifier sells 3 in-app purchases, starting at $6.99 per 7 days and Gem Identifier sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Gem Identifier holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Rock Identifier has 234 ratings behind it against 1, so its average is the more settled of the two.
