Mobile Application Development

Mobile Application Development Services for New or Existing Business

Since 2011 we've been performing the role of the remote app development team for companies who want to generate new or increase their existing business using mobile platforms. iOS and Android apps we develop put our clients' brands at their customer's fingertips. We've built more than 50 applications and we'd be happy to team up with you to implement your project.

Android app development

With our deep understanding of the material design and excellent knowledge of everything Android-related, we're one of those engineers you would want to be part of your team. Some of our older projects are built with Java. But today we mostly use Kotlin because it makes our code less verbose thus reducing the time for Android app development.

iOS app development

To build native iOS applications we use the latest technologies provided by Apple. Your app for iPhone, iPad or Apple Watch will execute code written in Swift or Objective-C. We are strict in maintaining the quality of code we write. It's readable, flexible, and testable. As we start working on your project you will get new and stable builds in your hands every week.

Cross-platform Flutter development

Some applications don’t need to be developed for iOS and Android separately. We can use one codebase for both platforms. Flutter is Google’s mobile app SDK that our team uses to develop apps covering both iOS and Android platforms. It's a perfect tool for MVPs and mobile apps that don't require complex functionality or communication with hardware via Bluetooth.

At Steelkiwi we design mobile apps that live on your customers' smartphones, tablets, and smartwatches

The cross-channel user experience brings convenience to customers and tons of benefits to businesses. To create this experience we can encapsulate all your website features in a mobile app, or let an app perform a limited number of functions.

Porting an iOS app to Android (or vice versa) cannot be done by merely replicating code in a different language. We will redesign your app in accordance with the platform conventions and build the entire functionality using native tools.

Being reliable as a partner. It's all that matters

The ultimate goal of our collaboration with our clients is to build the sort of relationships that last. We work hard to create the results that our clients expect. To do that we put a lot of emphasis on planning and project management. Here are the standards that we stick to at all times:

Managing risks in the Agile way

Before starting the project we evaluate all possible risks. They may include third-party services, business logic intricacies, and other things we don't know. We identify, quantify, and manage them in an Agile process.

Controlling change requests

Handling project schedules is always a challenge. Things can change and this is normal. We have a systematic approach to change requests. It allows us to keep the time and cost under control.

Making code maintainable

Writing readable source code is one of our main requirements to every project. Our mobile app developers stick to our internal coding standards and common conventions so our code could be easily maintained in the future.

Communicating transparently

For our clients, it's important to keep their projects under control and be aware of what's going on at any given moment. We have special rules for communication that ensure transparency and stakeholder involvement.
