The clearest difference is rating: Stone Identifier at 4.3 against Rock Identifier Stone Scanner+'s 1.7. Stone Identifier also leads on ratings volume (1.1K vs 6). Rock Identifier Stone Scanner+'s advantage is review sentiment (64% vs 24%) and ads (none vs shown). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. Stone Identifier sells 10 in-app purchases, starting at $2.99 per 7 days and Rock Identifier Stone Scanner+ sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
