Life isn’t perfect, and neither are we.
Most of the data we generate is based on information generated by the car computer, so inaccuracy is often caused by your car's ECU - even common data outputs, like speedometers, are known to have margins of error, which are sometimes surprisingly large.
In addition, we use the sensors in your phone, which can also have variability in some readings - especially GPS location accuracy.
Last, our mileage calculations for some hybrid and diesel vehicles are still a work in progress - but please try out Dash and use its other functions.
We’re working on improvements every day, so let us know if you have any feedback, by emailing us at firstname.lastname@example.org!
