To ensure device compatibility, we take and list down all devices that the client expects the app to be compatible with. Following which, we make sure the app is well tested on all the given devices. There also comes up a challenge where our team takes a ride in different vehicles, speed and areas and test the app.

We used GPS and Google Map to find the accurate distance. The distance is recorded by latitude and longitude. We do this programmatically to calculate the distance between the said start points to the destination via a given point with a 90-degree turn by dividing the distance into two sections. Starting point to crossing point and then from crossing midpoint to the destination. This gives us an accurate distance between two given points.

Besides ensuring device compatibility we make sure the app has a great design with intuitive user experience, be responsive and has a clear presentation using icons to guide the users. Our designs are initiated by understanding the context of their user. It is responsive: neither too heavy nor slow nor too tappy. Defining a correct balance of speed. In case if it is required to be slow at some point, it is clearly and accurately communicated via progress bar until the time of completion. Design Elements: reception buttons, proper segment control, controls offering a wide array of functionality, Navigation bars, temporary views as and where required and content views.
