Verdict
The clearest difference is price: CCA Remote at Free against CarHA's $4.99. CCA Remote also leads on iOS requirement (14.0 vs 16.6). CarHA's advantage is update cadence (weekly vs every 3 weeks) and chart position (#200 vs unranked). On ads, in-app purchases and device support there is nothing between them.
