The best meter app I could find and the only one suited for professional environment. Intuitive to use, great support. Most loved the segregation of roles (manager to setup tariffs and drivrr profiles) and drivers only login and start a trip. I can see all the trips of all my drivers on their website. Even idle trips I see. Now with OBD support it has even become better. Only wish I have: add support for payment with PayPal, dont like Square. Also loving the QR code with link to passenger receipt. Havent tried their backseat app yet but will do.
