Verdict
The clearest difference is rating: OBD2 Car Scanner at 3.8 against FasLink X's 2.9. OBD2 Car Scanner also leads on ratings volume (1.6K vs 116). FasLink X's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. OBD2 Car Scanner sells 3 in-app purchases, starting at $4.99 per 7 days. FasLink X asks for nothing beyond the download.
OBD2 Car Scanner holds the better App Store score, 3.8 against 2.9. That said, the two scores are not equally well evidenced: OBD2 Car Scanner has 1.6K ratings behind it against 116, so its average is the more settled of the two. Written reviews complicate that: 21% of FasLink X's written reviews are positive against 4% of OBD2 Car Scanner's, so the app with the better star average is not the one people write more warmly about.
FasLink X ships an update every 2 weeks, OBD2 Car Scanner every 2 months. The most recent releases landed on November 3, 2026 and November 12, 2026 respectively.
