# Rock Identifier vs Gem Identifier

The clearest difference is rating: Rock Identifier at 4.6 against Gem Identifier's 3.7. Rock Identifier also leads on monetization model (free with in-app purchases vs subscription) and ratings volume (36 vs 3). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Rock Identifier sells 2 in-app purchases, starting at $6.99 per 7 days and Gem Identifier sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Rock Identifier holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Rock Identifier has 36 ratings behind it against 3, so its average is the more settled of the two.
