What apps and Extensions are available today?

• There are no official apps for Hammerhead devices using the new Hammerhead Extensions repository (karoo-ext). We are working with various partners and app developers to make apps more accessible on our bike computers.

What support is available for Hammerhead Extensions?

• Hammerhead does not provide support for the development of third party applications for our devices. Third party’s are responsible for the development of their applications. We have created a Hammerhead Developers community forum for developers to interact with each other to support and help each other with the development of Hammerhead Extensions.
