Verdict
The clearest difference is review sentiment: oCFR at 50% against Decon Field Guide's 0%. oCFR also leads on monetization model (free vs ad-supported) and iOS requirement (11.0 vs 15.1). Decon Field Guide's advantage is rating (4.6 vs 3.7) and update cadence (every 2 months vs every 6 months). On price, ratings volume, ads and in-app purchases there is nothing between them.
