Mobile app development process

What is cross-platform mobile app development?

Cross-platform mobile application development is building applications with a single, shared codebase that can then be delivered to multiple platforms at once, including Android and iOS. The application can be then made available for web and desktop.

This way, the final product is easier to maintain and develop further, and you don’t need two or more teams to do that. Reach your users anywhere, any time.

Benefits of cross-platform
mobile app development

Save money

One team that works in the same technology which means smaller costs and improved team scalability.

Launch faster

Faster time to market: you can build and launch multiple versions of your product at the same time.

Customize your product

Apps share the source code and the UI, so you can code and design your product once, and then enjoy the quality on two or more platforms.

React Native Logo

React Native

React Native was introduced in 2015 by Facebook. It combines native development with business logic in React.

It provides great responsiveness and performance for both iOS and Android, and has a huge developer community, with a wide range of ready-made features and libraries.

It is a tried and trusted framework that offers support for web thanks to React Native Web.

Flutter Logo


Flutter was built and is maintained by Google, and allows you to develop highly-performant applications that work on any screen, with adaptive designs and multi-platform approach in its DNA. The technology is now used by large companies such BMW, Crédit Agricole, and Alibaba Group.

Capacitor Logo

Ionic with Capacitor

Ionic is another software development kit that we use at Monterail when working with our clients.

Paired with Capacitor, it’s a powerful tool for building applications quickly and securely, with accessible user interfaces and seamless user experience. It’s also ideal for connecting it with your existing web application.

From startup to stable business with an award-winning app

To deliver an innovative user experience, and appeal to corporations, we started an intense and thorough planning: 120 hours of design workshops and in-depth analysis of the product. The PM was a consultant and translator for the technical and business stakeholders. In just 2 months we delivered an MVP with a novel idea and new features for the product.

20% monthly increase in the app's usage

The app was first released to beta testers in July 2018 and four months later we released the app to app stores with all the features we planned at the first release. The Guild team kicked off this year with a bang, raising $1.2M (£880.000) in seed funding for further development and growing sales. Since then, Guild has been recognized by Red Herring's 2019 Top 100 European Startups.

Professional development and communication

Even though we’re based in Atlanta and the pace of development is crazy sometimes, we never had any communication issues with the team in Wrocław. Each stage of the software development was conducted professionally and in a timely manner: from the concept, through implementation to final steps.
