Verdict
The clearest difference is in-app purchases: DND HD+ at none against Carista OBD2's 14. DND HD+ also leads on ads (none vs shown) and iOS requirement (12.0 vs 16.4). Carista OBD2's advantage is update cadence (every 3 weeks vs every 2 months) and chart position (#186 vs unranked). On price and device support there is nothing between them.
