Verdict
The clearest difference is ads: RockAiSnap at none against Stone Identifier's shown. RockAiSnap also leads on rating (4.7 vs 4.3) and device support (3 vs 1). Stone Identifier's advantage is ratings volume (1.1K vs 3). On price, update cadence, in-app purchases and monetization model there is nothing between them.
