Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
OBD2 Trouble Code is free to download; Engine Link costs $5.99 up front. Neither carries in-app purchases, so what you see is what you pay.
OBD2 Trouble Code holds the better App Store score, 3.3 against 2.9. Both are backed by a comparable volume of ratings — 62 and 306 respectively. Written reviews complicate that: 38% of Engine Link's written reviews are positive against 37% of OBD2 Trouble Code's, so the app with the better star average is not the one people write more warmly about.
