Verdict

The call

ReceptionRating · Positive reviews · Number of ratings

Smart Car Key holds the better App Store score, 3.8 against 3.0. That said, the two scores are not equally well evidenced: CL6 has 280 ratings behind it against 53, so its average is the more settled of the two. Written reviews complicate that: 50% of CL6's written reviews are positive against 0% of Smart Car Key's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CL6 ships an update monthly, Smart Car Key daily. Both last shipped on October 24, 2026.
