Verdict

The call

The clearest difference is ads: Milestone at none against Carista OBD2's shown. Milestone also leads on update cadence (every 5 days vs every 3 weeks). Carista OBD2's advantage is chart position (#168 vs unranked) and iOS requirement (16.4 vs 26.0). On price, in-app purchases and device support there is nothing between them.
