Carista is a mobile app and OBD2 (On-Board Diagnostics) scanner combo that allows users to diagnose, customize, and service their cars right from their smartphone. By empowering users with real-time insights and convenient controls, Carista helps drivers take better care of their cars and tailor their driving experience—all through an intuitive mobile experience.

The challenge
To keep drivers both informed and excited about what’s new, Carista needed a reliable way to reach them quickly and consistently. OneSignal made it simple to share updates, announce deals, and highlight new features, all within the mobile experience their customers rely on.
The difference-maker?
OneSignal has definitely helped us move faster. Using in-app messages means we don’t have to build custom screens or wait for app releases—it makes us more agile and less dependent on engineering.

How they engage
Carista uses push notifications to reach users instantly with timely updates and leverages email to provide more detailed information when needed. This combination ensures clear, consistent communication throughout the customer’s ownership journey.

We’ve noticed that our sales increase on days when we send push notifications or emails about promotions.
The payoff
A 31% increase in hardware sales and an 85% month-over-month boost in user reactivations—that was the result of a single push campaign Carista launched using OneSignal to promote their latest app update. The message drove 2,000 users to their website and earned a 5.45% click-through rate.
In another campaign, Carista saw a 19% lift in hardware sales and a 77% increase in GM-related user reactivations after targeting nearly 4,000 app users with a special offer for GM car owners. Delivered via OneSignal, the push notification drove a third of that day’s website visits and achieved a 5.94% CTR.
