Verdict

The call

The clearest difference is rating: OBD2 Car Scanner at 3.8 against HT200's 1.9. OBD2 Car Scanner also leads on ratings volume (1.3K vs 303). HT200's advantage is ads (none vs shown) and review sentiment (15% vs 4%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

OBD2 Car Scanner holds the better App Store score, 3.8 against 1.9. Both are backed by a comparable volume of ratings — 303 and 1.3K respectively. Written reviews complicate that: 15% of HT200'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.

UpkeepUpdate frequency

HT200 ships an update every 6 weeks, OBD2 Car Scanner every 5 weeks. The most recent releases landed on September 23, 2026 and September 28, 2026 respectively.
