Book a Taxi
Anytime & Anywhere


Sandra Taxi app is one of the best on-demand taxi apps that help customers to benefit fast and comfortable rides within minutes. It won't take much time to avail of their first ride with a smooth signup process and uncluttered UI. The user needs to set pickup, and drop-off location, select car type from available options, and then the user will get ride confirmation within a few seconds. Once the trip ends, the customer will get a payment invoice and pay the fare by cash or card. An app allows tracking driver's location, getting fare estimation, and tracking ride history conveniently. Customers can book ride for immediate use or later. If the user is lucky enough, they can get a free or discounted ride using discount code. The best part of this app is that it's not necessary to enter drop off location, its optional, so whenever the customer wants to stop the ride, they can do it. The amount will be calculated according to the distance of the drop off location. If a customer paid extra, they would get discounted from the next trip, and in case the customer paid less than the actual amount will be added to the next trip. Sandra taxi app contains two apps; one is for the customer, and the second is for drivers. Drivers need to register through an app by providing required documents, and if a driver wants to train by any experts, then he/she can register for it.

Client Requirements

Our client approached Hyperlink InfoSystem to make a taxi app where people can experience safe, swift, comfortable, and time-saving service and also can be easily synced with the movement of the car on a driver and customer app within a few simple clicks and add to that the client wanted to develop a taxi app where customers can book a ride without filling drop off location. The client's main aim is to make an online platform that connects customers and professional drivers where customers can travel into a different area while enjoying the best transportation in a cost-effective amount, and drivers can earn extra money by riding a taxi. Hyperlink InfoSystem developed two apps as per the app functionalities, and clients demand where customers can easily book their hassle-free taxi ride.

Distance Calculation

When a user selects pick-up and drop-off location, the system automatically generates & sends fare estimation to the user. But, there are scenarios where single destinations may have multiple routes. Calculation of fare estimation based on the selected destination route and sending fare estimation based on selected route distance was hard and challenging. However, using some technical function of a particular class, our developers calculated the distance and managed the scenario quite efficiently.

To Display Proper Path

After selecting the pick-up and drop off location, the ride request is sent to the driver. If the driver accepts the ride request, the next screen shows the entire path from pick-up to drop off. Drawing polyline over the whole course was quite complicated and time-consuming. Our development team handled this scenario by applying technical methods to draw polyline of the entire route from pick-up to drop-off.
