Mobile App Development Services

At Railwaymen, we pay great attention to professionalism. That's why our team includes experienced mobile app developers. Our experts build mobile apps quickly and, most importantly, accurately. Thanks to this, you don't have to worry about the quality of your commissioned project.

We don't limit ourselves to only web applications. So if you want to receive a top mobile app that works smoothly on your users' mobile phones - we are the right choice! You can find our solutions in both the Apple App Store and Google Play Store. The process of cross platform development is not the slightest problem for us, as evidenced by previous projects that are on multiple operating systems.

We focus on building functional, well-designed and fully tested mobile apps. Based on your project scope we will advise you whether you should choose native apps or cross-platform development approach. As a result - you will receive a mobile custom software perfectly adjusted to your users needs!

Our Mobile Development Tech Stack

To provide the best mobile solutions we use native device features (for iOS & Android) and cross-platform technologies.

  • Swift logo
    Swift
    It's s a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. and the open-source community, first released in 2014. Swift was developed as a replacement for Apple's earlier programming language Objective-C.
  • Java logo
    Java
    It is a class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. As of 2019, Java was one of the most popular programming languages in use according to GitHub.
  • Kotlin logo
    Kotlin
    Kotlin is a modern statically typed programming language used by over 60% of professional Android developers that helps boost productivity, developer satisfaction, and code safety. It's a cross-platform, statically typed programming language.
  • React Native logo
    React Native
    With the help of this innovative, created by the Facebook framework we are able to build cross-platform mobile apps. It is used to develop applications for Android, Android TV, iOS, macOS, tvOS, Web, Windows, and UWP.
  • RxSwift logo
    RxSwift
    RxSwift's intention is to enable easy composition of asynchronous operations and streams of data in the form of Observable objects and a suite of methods to transform and compose these pieces of asynchronous work.
  • CoreData logo
    CoreData
    Core Data abstracts the details of mapping your objects to a store, making it easy to save data from Swift and Objective-C without administering a database directly.
  • Room DB logo
    Room DB
    Room is a database layer on top of an SQLite database. Room uses the DAO to issue queries to its database. By default, to avoid poor UI performance, Room doesn't allow you to issue queries on the main thread.
  • RxKotlin logo
    RxKotlin
    It's a lightweight library that adds convenient extension functions to RxJava. You can use RxJava with Kotlin out-of-the-box, but Kotlin has language features (such as extension functions) that can streamline the usage of RxJava even more.

The Tools we Use For Project Management

We refined our mobile app development process over many years, paying special attention to communication within the team.

Communication is the key to a successful cooperation - we know that, so we use special tools to maintain it.

  • Jira logo
    Jira
    Jira is our choice for an agile project management tool. It combines task tracking and Quality Assurance tools. Using Jira enables us to work smoothly despite any time differences between us and the client.
  • X-Ray logo
    X-Ray
    Xray is a complete Test Management tool for Jira, supporting the entire testing life cycle: test planning, test design, test execution and test reporting. This helps to improve the quality of our systems through effective and efficient testing.
  • Slack logo
    Slack
    We use Slack for day-to-day communication between the development team and client/customer. Built in integrations (eg. with Jira or Google Docs) allow us to easily focus on what's important.

Quality Assurance

Our QA team will break your app mercilessly, to identify and fix all of its weak spots!

In each mobile development process, we require 100% test coverage from the early beginning. It's a part of the test requirement so that the whole test case will not pass unless the code is fully covered. Additionally, we do code reviews in which developers can check the quality of unit tests and make sure that all parts of the code are properly tested.

We automate all the tests that are crucial and focus on critical areas of the mobile application. Our team always leverages the amount of time and work needed to create and maintain the automated test sets against the ability to manually follow test cases. However, each application is different. Customer awareness of the automated tests is also an important factor we take into account.

Tools That We Use for Testing & QA Automation

We know how important it is to use mobile applications smoothly and without errors. That's why we perform thorough platform testing on all mobile operating systems so that users enjoy the capabilities of our applications on their mobile devices.

You can read more about tools used by our QA team here.

  • RSpec logo
    RSpec
    It’s a unit test framework that is the Behaviour-Driven Development tool for Ruby programming language. RSpec provides a domain-specific language to describe the behavior of objects.
  • Selenium logo
    Selenium
    This is a toolset for browser automation which provides Web GUI tests. Selenium is treated as an umbrella project for many tools and libraries which support automation testing. We are using selenium together with Java and the TestNG framework.
  • JUnit logo
    JUnit
    The unit testing framework for the Java language which allows us to write repeatable tests. It is a very important element in the Test-Driven Development process.

Code Distribution

Each portion of code is thoroughly checked by us - everything, to maintain the highest quality!

We're doing code review for each portion of the delivered code and covering the whole code with unit & function tests. Thanks to usage of Continuous Integration and Continuous Delivery we're able to limit time spent on app distribution.

    Unless you are a highly technical product manager I suggest getting a PM. Not only will they help manage your engineers while you're asleep (granted you live in the West) but they provide a much needed buffer for some of the less technical clients to ask questions to. Also much easier to plan meetings and agendas with them as they will be much more communicative. Railwaymen goes above and beyond to provide high-quality results at reasonable rates. The team is hard-working and organized, establishing a smooth workflow. They've quite literally built everything from the ground up and there wouldn't be a product without them!

We did this in a very short time even we had a lot of obstacles. Building the base in a very professional way and as per the standard with the alignment of the up-to-date technology helped us to start another project with them (KIOSK “self-service”) in very short notice and finished it as planned.

Our Values

What we believe in strongly reflects on how we build our software - and it simply works.

Building business-focused mobile and web solutions
While developing your product the main goal in our heads is usability. Your custom software has to increase your business revenue. Streamline your processes. Bring you lots of new customers and enable you to outrun your competitors. Those are the things that are the most important to you. So obviously they are also priorities for us. Before starting the development stage, we always want to make sure that your app idea is validated.
Providing outstanding & high-quality products
How to recognize a bespoke software of a truly superior quality? Despite the passage of time and trends changing - it works. It's stable, reliable and it grows together with your business. We are web development company, who are constantly learning and improving. 100% test coverage is one of our main principles. Trust us, and we will move heaven and earth for your project!
Building long-term customer partnerships
What we've noticed during +10 years of our company's existence is that software is never “done”. Just like the world around us, your app also has to evolve and change to survive. We will be there for you, celebrating your app's 1st, 5th or 10th anniversary - constantly developing it and making sure it answers your current needs. And if you'll want to press "stop" on your project we also understand it - we'll be happy to work again when the right time comes!
