Mobile app development for iPhone, iPad and Android

We design, build and support mobile apps: native iOS and Android, or one cross-platform codebase, with the web admin and back end behind them. Mobile apps are a large part of our work, and you own the code we write for you. For apps that pair with hardware, see IoT application development.

Mobile app services

Each area has its own page with examples from our case studies.

iOS app development

Native iPhone and iPad apps in Swift, from point-of-sale apps to parcel maps. See iOS development.

Android app development

Native Android apps in Kotlin and Java. See Android development.

Cross-platform apps

React Native, Flutter and Ionic apps from one codebase. See cross-platform apps and Flutter.

App design

Screens, prototypes and user testing before development. See app design.

Back ends and admin panels

APIs, dashboards and databases behind the app, in Node.js, PHP or .NET.

Support and updates

Store releases, updates for new OS versions, fixes and new features after launch.

What an app project includes

Most of our app projects follow the same path, whatever the platform:

  • Screens first. We agree the flows and design before development starts. See app design.
  • Built in stages. You get test builds to install on your own phone as features land.
  • The parts users never see. The API, the admin panel and the database are built alongside the app.
  • Store releases. We prepare and submit the App Store and Google Play releases.
  • After launch. Updates for new iOS and Android versions, fixes and new features.

What clients say

When I saw Shawinder profile for the first time, I saw someone gave him a low score for communications, I was afraid about that but I hired him anyway, and frankly speaking, Shawinder communication is fantastic! He was always available online for me, he does review and discuss each task to make sure everything is clear from both side, and he kept me updated every day about the status, I wish I can give him more than 5/5 in communication!.

Communication 5/5

From the quality of work point view, he is also amazing, he does clean code, and Shawinder will also test the functionality before he hands it over to me to check it.

Quality of work 5/5

I will close this contract because this project completed, but I will open a new one for another project with Shawinder.

Deadline 5/5

Frankly few people amazed me in Upwork, Shawinder is one of them!.

We are a UK based company, that this was our first hire via oDesk, building out a very complex iPhone application. I've completed some very complex work with the help of Gursharan, used main different aspects of the iPhone SDK - StoreKit, GPS, Table Views (All widgets), CoreData, CoreAnimation, CoreGraphic and so on. Gursharan has met these challenges head on and delivered consistently.

Communication via Skype has been excellent, and he has taken my specifications and interpreted these into good quality, crash free code.

I'll be hiring him again soon.

This coder is a coder that first off all you can trust on.

I have allot of experience in the outsourcing business and it is very hard to find someone that understand all your tasks, provide the end project on time and delivers a great result with a smooth code.

This kind of person is Ankit Verma, his service was great, and he listened to all of our needs and read carefully our specification.

Great coder to work with, we will definitely continue to work with him in the future in other projects.

Rakesh is a competent and hard working developer. We worked together to design an app using bluetooth connectivity. He was able to understand the obstacles we faced and overcome them.

Since we live in very different time zones, communication and availability was tough. But there were many occasions when he stayed late after hours to continue working on the project.

I would definitely work with Rakesh again, and recommend him to anyone seeking a developer.

Hemant has communicated with us every step of the way without having to be tugged. He has completed every task that was requested in a timely manner and to specifications and satisfaction. We find him willing and capable in every aspect of application development and he let's us know if something is not clear. We will continue to work with him on additional aspects of this project as well as future projects.

Neelesh was excellent to work with! He was dedicated to the project and took extra measures to work late into the night on multiple occasions to adhere to our very expedited timeline. He was very cooperative, even when last minute changes/requests were made last minute. The iPhone app works great! Neelesh will definitely be getting more work from us!

Frequently asked questions

What kinds of apps do you build?

Mobile apps for iOS and Android, web apps, game and sports apps, and cross-platform apps. See our iOS, Android and hybrid pages.

Do you design the app too?

Yes. See our app design page.

Native or cross-platform: which should I choose?

Native gives the best performance and device access. Cross-platform can cover both iOS and Android from one codebase. We help you choose for your app.

Do you sign an NDA, and who owns the code?

We sign an NDA before work starts, and you own the code we write for you.

How do I get a quote?

Use the form on this page or book a project call. Tell us what you need and we come back with questions and next steps.

How can we work together?

There are three ways, on the same terms:

  • Dedicated team, best for ongoing work: interview the developers, then they work on your project full or part time.
  • Fixed scope, best when requirements are clear: we agree the scope and the price up front, and deliver against it.
  • Time and material, best when the scope will change: you pay for the time used and can change priorities as the work goes on.

Whichever you choose, we sign an NDA before work starts, you own the code we write, and every change is reviewed in your repository.

Can I interview the developers before we start?

Yes. For a dedicated team you meet the developers in an online call and interview them before they join your project.

Have an app in mind?

Tell us what you need built, fixed or replaced. We come back with questions, a suggested approach and an estimate.
