Kerbz is the social platform for car enthusiasts. Whether your weekends are cars & coffee, a club meet, a show, a canyon drive or a track day, it's one place for all of it — the events, the cars, the people and the parts. YOUR GARAGE Add your cars once. Kerbz uses them everywhere: to find the events, the discussions and the parts that fit what you drive. THE PADDOCK Talk with people who own the same car. Builds and setups, where to meet, which track, what tires — organized by car and generation, so an answer comes from someone driving the same thing you are. THE MARKET Parts, wheels, tires, seats and gear, sold driver to driver. Every listing says what it fits, and every seller is a real driver you can look up — their cars, their events, their past deals. Meet at the next event to hand it over. EVENTS Discover and register for cars & coffee, car shows, club meets, track days, HPDE and autocross in a few taps. Add friends and see who's going. Group registration for your club or team. Your calendar keeps it all straight. ON TRACK Live timing during the event, lap records and personal bests afterwards, leaderboards by track and car. Share a lap and compare it against a friend's. RENTALS Book a track-ready car from a trusted host when you don't want to bring your own. COMMUNITY A feed of what your friends are doing, messaging, badges for the miles you've put in, and a profile that shows what you drive and where you've been. From someone who's never been to a track to someone who never leaves one, Kerbz is built for people who love cars and the weekends that come with them.

Verdict
The clearest difference is update cadence: Kerbz at daily against Garmin Catalyst™'s monthly. Kerbz also leads on review sentiment (100% vs 80%) and rating (5.0 vs 4.8). Garmin Catalyst™'s advantage is ratings volume (120 vs 8). On price, ads, in-app purchases and monetization model there is nothing between them.

Kerbz holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Garmin Catalyst™ has 120 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 80% of Garmin Catalyst™'s written reviews are positive against 100% of Kerbz's.
Garmin Catalyst™ ships an update monthly, Kerbz daily. The most recent releases landed on October 21, 2026 and October 12, 2026 respectively.

Reported bugs
7 issues- Everytime you try logging in the app just glitches anyways can’t even get logged in.
- Comparing to others frequently fails
- Compare to friend feature way to frequently fails with the message about the tracks not matching well enough despite being the same track on the same days even.
- New version is off
- It won’t let me compare the laps with other friends on the same day. Says lap not similar. Literally same day same track same session.

- Friend integration is currently pretty lacking. When I try to compare laps it complains that the tracks aren't similar enough.
- Worse though is that there's no apparent way of sharing your sessions with friends.
