Car gear that pairs with AXLY

Start here: an OBD2 adapter

AXLY talks to your car through a Bluetooth LE OBD2 adapter — it's the one piece of hardware you actually need. Everything else on this page is optional.

Then: the AXLY dashboard kit

A phone mount and a fast charger are all you need to turn your phone + AXLY into a free dash cam, a live digital dashboard, and a drag-strip track timer.
