Verdict
The clearest difference is review sentiment: CL6 at 50% against Smart Car Key's 0%. CL6 also leads on in-app purchases (none vs 2) and ratings volume (280 vs 53). Smart Car Key's advantage is rating (3.8 vs 3.0) and update cadence (daily vs monthly). On price, ads and device support there is nothing between them.

Both are free to download. Smart Car Key sells 2 in-app purchases, starting at $6.99 per month. CL6 asks for nothing beyond the download.
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.

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