Verdict

The call

The clearest difference is rating: Rock Nerd at 4.7 against Rock Identifier's 4.3. Rock Nerd also leads on device support (3 vs 1) and iOS requirement (15.1 vs 18.0). Rock Identifier's advantage is review sentiment (67% vs 50%) and update cadence (every 3 days vs every 9 days). On price, ads, in-app purchases and monetization model there is nothing between them.
