ReceptionRating · Positive reviews · Number of ratings

RSCHIP CHIPTUNING holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: OBD2 Scanner | OBD Auto Doctor has 6.2K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 30% of OBD2 Scanner | OBD Auto Doctor's written reviews are positive against 25% of RSCHIP CHIPTUNING's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

OBD2 Scanner | OBD Auto Doctor ships an update every 3 weeks, RSCHIP CHIPTUNING every 2 months. The most recent releases landed on October 21, 2026 and October 19, 2026 respectively.
