About

Dashmazing

Read full description

Dashmazing is an OBD2 app that lets you display real-time engine information in customisable dashboards. Measure your car's acceleration and and optionally use your phone's camera to record the acceleration measurement. Analyse your engine by viewing up to six telemetry graphs at once. You can also create trips and get more information for like minimum values, maximum values, average value and total values (eg. total fuel consumed) With a one-time purchase the full version unlocks every dashboard theme and layout, acceleration recording and telemetry trips, while the free version allows you to test the functionality of the app. You require a car that supports OBD-II, which most cars do, since car manufactures are legally required to support OBD-II in all major regions of the world for emission regulation purposes. For Dashmazing to be able to communicate with your vehicle you also require an OBD Adapter using Bluetooth LE with iOS support. There are many different options available. Dashmazing works with the common ELM327 command set. Once you have connected to an adapter, Dashmazing will remember it and automatically reconnect to it every time you open the app.
