# Rock Identifier vs Crystal Identifier

The clearest difference is rating: Rock Identifier at 4.5 against Crystal Identifier's 3.3. Rock Identifier also leads on ratings volume (235 vs 4). 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 Crystal 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.
