Verdict
The clearest difference is price: UMA Expo at Free against Prevost OBD Code Converter's $9.99. UMA Expo also leads on update cadence (every 7 months vs every 24 months) and device support (4 vs 2). Prevost OBD Code Converter's advantage is ads (none vs shown) and chart position (#95 vs unranked). On in-app purchases there is nothing between them.
