On-demand applications form an immediate solution to real-world problems for users. UberEats delivers food items from your favorite restaurant right at your doorstep. With Airbnb, you can book a room in the strangest of the cities across any part of the globe. With on-demand apps, the world seems so easy and hassle-free.

The comfort that it renders and the way it has been gaining user’s attention makes it a local service provider’s first choice. Over the years, more and more businesses have implemented these apps to expand their customer base and retain them for good.

The giants of app developers have reciprocated with great interest. The likes of Uber for X projects have shown up to encourage similar real-world solutions for nearly every business domain. The result: the app world is getting introduced to a new business niche every other day allowing the developers to expand their skills and prepare themselves for digitalizing more offline jobs.

On-Demand Apps Are Rich in Features

An on-demand service plays as a middleman between the local service providers and the users, eventually minimizing the efforts of vendors at marketing their presence. With the new-age features, apps let your users find you more precisely. In fact, the apps handle a big chunk of the job, right on the screen.

For example, the Fandango app serves a majority of movie buffs in the US. The app lets the users find their favorite movie, locate their favorite theatre and book seats of their choice. The working model is very close to the following:

  • The users sign up on the app
  • They search for the movie
  • Next, they confirm the day they are planning to watch the movie
  • The app brings up all the theatres that are running the said movie along with the showtimes
  • The users select the theatre of their choice along with the showtime
  • The app disables the seats that are pre-booked
  • The app only shows the seats that are available for booking
  • The user confirms the seats and proceeds for checkout
  • The payment gateway processes the fee and the seat is allotted for the said day and time slot

We have emphasized the location and schedule here, for a definite reason.

  • Sign up pages are way too common and their designing has already been discussed
  • The list of movies is temporary and can be readily managed from the backend of the native app
  • The location has to be area-bounded, you can’t let your users order something from 300 miles
  • The scheduling can’t be compromised in any terms as the term “On-Demand” starts diluting

How Did We Control the Distance and Scheduling?

Our developers have worked in several projects in the recent past where the client is deeply interested in organizing the service providers and the users on the same screen with the same conditions and challenges mentioned before.

Location With Distance Matrix

We used the Distance Matrix API to address location-based issues. The API provides information regarding travel distance and the time for a matrix of the origins and destinations. This makes it easier for the developers to track real-time locations of the users and that of the service providers on the Google Map.


The API can communicate between the app and the Google map to allow more precise pairs between the start and endpoints. In the meantime, each party can track the other in real-time.

Further Challenge

What if the said vendor is absent? Will the app terminate the services?

A big no to that. On-demand apps are a marketplace for physical services. With Distance Matrix being added, the user is availed with multiple service providers on the same screen. Developers can run algorithms to manage the switch between the providers.

The best example is Uber.

  1. A user confirms the endpoints of the journey
  2. The app reaches out to the nearest driver for the job
  3. If the driver cancels the ride, the app reaches out to the next driver in the vicinity

We tried to clone the approach with a round-robin algorithm. The temporary unavailability of any laborer in the loop is thus well compensated. The app prioritizes the laborers based on their respective distances with the user/employer. As explained earlier, the Distance matrix is the one making the best pairs out there.

Confirming Schedule With Calendar API

On-demand apps are best known for their abilities to automate their services based on schedules. For example, a user wants a movie ticket for the upcoming weekends, which are 4 days away. The app requires a two-way serving calendar that helps the user to confirm his bookings on the said day, while it also confirms the app and the theatre about the booking for that day.

We customized the react-native calendar API to manage the stuff. The calendar by itself wasn’t much flexible with modifications. We added libraries to render date ranges. The laborer can thus mark string of dates for his unavailability. The Calendar API synchronizes with the app to disable the laborer’s availability for those days.


We have a gif file here: Managing availability

In the above example, the worker marks himself available between only 16 and 29. As a result, when a user asks for a service, the app only pings this laborer between the said dates. For the rest of the days, the laborer doesn’t receive any request.

Concluding Words

  • On-demand apps justify their name i.e., the user receives the services whenever he wishes
  • On-demand apps meet custom needs more precisely
  • Developers can use similar layouts for multiple business niches
