This blog covers every technical detail you must be knowing in order to build an on-demand taxi app solution.

Before we go technology-deep into the idea of on-demand taxi solutions, we need to understand the meaning of this term. So, what does it mean when you say on-demand cab or taxi app solution. Well, on-demand taxi solutions are about offering users a way to connect with transportation services at their call using a system interface. So, they are able to reach any destination from their source location, booking a cab through a connecting platform, mostly a mobile app.

But, being an on-demand taxi service takes a lot of performance optimization and seamless connectivity across the channel. It has to be as effective at the backend as it is on the front. So that it can be always ready to offer services to users as and when they demand for it.

Now, the best example of this is Uber, that owns the most number of taxis and is most popular among users worldwide. And to the most of your surprise, it doesn’t own a single vehicle. So, what makes Uber so viable and acceptable. It’s the on-field performance and the technology working behind it.

Which makes one thing clear, that you cannot do it without a resourceful technology system to support your operations, communication and on-demand offerings at the customer-front.

This clearly requires you to opt for the right technology stack to make it to an effective on-demand taxi solution. Understanding this gets easy by breaking your solutions into different simpler modules and features. Here’s how it goes:

Geo Location

Location services are basic to any on-demand taxi app. For any person to avail your services they need to be able to locate the taxis. Quite similarly drivers should be able to locate passengers and there should be route tracking facility available to make services more prompt and viable. So, what all technologies you need to work on to bring the entire component of Geo Location together to build location services for your app. If you are building Device’s location component for iOS, you need to work on Core Location Framework. If it’s Android, you have to work with Google’s Location APIs. While working on navigation for iOS users you have MapKit to work on and for Android it is Google Maps Android API.


An on-demand taxi app needs to keep user updated and served with frequent notifications. Whether it is in the form of Push Notifications Services, SMS, and Email, the messages and alerts you send across should be in best of their shape and should be delivered on time.

Notifications can be divided into two functional types. Push Notifications and Text Notifications. Push Notifications can be highly effective as they are more noticeable and appealing form of messaging. But in case the internet goes down or a user is offline, Text Notifications ensure delivering the message right on mark.

For iOS users it’s Apple Push Notification Service and for Android users it is Google Cloud Messaging. Both are same in all aspects, but one – APNS does not allow you to know if the message was delivered or not, however it is not the case with Google Notifications.

Notifications that are sent in an on-demand cab solution:

  • Driver: Accept or decline ride
  • Rider: Ride accepted/cancelled
  • Rider: Ride Arrival
  • Rider: Surge Pricing Over
  • Rider: Fare Updated

In case of SMS notifications Twilio is the market leader with clients like Uber, Netflix, Hulu and Lyft in its kitty. Other close options are Nexmo, Plivo, and Sinch.

Inter app communication

In case of an on-demand taxi service there are two apps establishing the communication for users. One is for drivers and other for passengers. These apps need to communicate with each other at different points and that’s how the service flows and operations take place. Here, these two applications act as two interfaces to service, connecting both the ends – which allows passengers to book the service and drivers to provide the service while accessing app for supporting aids and assistances.

Here’s how these two apps communicate with each other in different ways:

  • Send/accept booking request
  • Current location detection
  • Direction tracking
  • Ride/Fare calculations
  • Chat and messaging
  • Ride rating and review
  • Cancel request – both ways

The communication between apps takes place over mobile data or Wi-Fi. There’s a data traveling protocol that decides the flow of communication. This could be encrypted or non-encrypted depending on the provider’s choice. The data is routed through an application server to the destination points. The quality of data again depends on the supporting system and the data exchange resources backing it.


Payment is the most significant part of any on-demand cab service app. And it is primarily based on the cashless payment system sourced through a payment gateway. Braintree is one of the leaders in the mobile payment market segment and has premium clients like Uber to boast. Stripe is another payment services option that offers equally dependable and prompt service and is a quite prominent player in the domain. These services also offer a split payment feature which allows the whole act of billing and payment much more user friendly. Another great extension to the facility is payment scanning service offered by PayPal’s that allows your phone’s camera to scan credit card and this is available for both iOS and Android users.
