Taking Jaguar's ReRun app testing on the road

Conjure is a digital product agency that worked with Jaguar Land Rover (JLR) to develop ReRun, a mobile app designed for the Jaguar F-Type sports car.

ReRun connects a GoPro camera with data from Jaguar's InControl infotainment system, allowing drivers to create videos of their journeys overlaid with performance information, including speed, G-forces, throttle, braking and gear selection.

Testing beyond the usual environment

ReRun needed to work across different mobile devices while communicating reliably with both the vehicle and an external camera.

To test these connections properly, Conjure needed a independent testing partner who could work across iOS and Android devices and, importantly, test the app in a moving Jaguar F-Type.

We developed a test plan with detailed scripts covering the different components of the app, giving the team a repeatable way to check its functionality against JLR's requirements.

Putting ReRun through its paces

Our testers worked alongside Conjure during several in-car testing sessions, checking how the app performed across its target iOS and Android devices.

Testing in the vehicle allowed us to assess the interaction between the app, GoPro camera and InControl system under real driving conditions. We documented issues with clear reproduction steps, helping Conjure's developers understand and address them efficiently.

A successful launch and wider recognition

ReRun launched successfully and attracted coverage from publications including Forbes and CNET.

The project also caught the attention of GoPro, which joined Jaguar Land Rover for a PR and marketing campaign, bringing the app to a wider audience. Following the F-Type launch, JLR commissioned a version of the app tailored for Land Rover.

For Conjure, our testing provided practical support throughout development, combining structured test coverage with the flexibility to test a complex connected experience in the environment where it would actually be used.
