Verdict

The call

The clearest difference is in-app purchases: iNaturalist at none against Camera Dictionary's 1. iNaturalist also leads on ads (none vs shown) and chart position (#88 vs unranked). Camera Dictionary's advantage is update cadence (daily vs fortnightly). On price and device support there is nothing between them.
