Cross-Platform Mobile App Development
Develop your application for multiple platforms at once: Android, iOS, web, and even desktop.
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.
What are the benefits of this approach?
One team that works in the same technology which means smaller costs and improved team scalability.
Faster time to market: you can build and launch multiple versions of your product at the same time.
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.
Native vs. web vs. cross-platform development
Feature | Native development | Web-only and PWA | Cross-platform development |
---|---|---|---|
Device access to features such as camera, microphone, Bluetooth, push notifications, and localization | Full | Limited | Full (with plugins) |
Development language | Swift/Objective for iOS and Kotlin/Java for Android | HTML, CSS, Javascript | Dart - Flutter Javascript (React) - React Native HTML, CSS, Javascript - Hybrid development |
Time to market | Slow if you target both iOS and Android | Fast | Medium to fast - you can develop three or more platform-specific applications |
Code reuse | No | Yes | Yes, up to 100% of your code can be shared between platform-specific versions of your application |
Maintenance costs | High | Low | Low to medium |
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.
React Native is a highly performant framework with a single codebase used for developing platform-specific components. They can be then merged with existing code, with changes implemented instantly.
With its focus on delivering flawless UI, React Native renders Native UI for both iOS and Android. This results in applications loading swiftly, with no visible differences between different platforms with native patterns in place.
When you need to build a complex, engaging application that uses a lot of device's resources but stays perfectly performant or want to add a web application in the same codebase, React Native will be the best option.
Flutter
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.
The framework uses its own widgets, so you won’t have to overcome compatibility issues between different iOS and Android versions.
By design, Flutter handles multiple animations and visualizations, all that while keeping the motion silky smooth with 60-90 frames per second.
Flutter allows you to keep your product performing flawlessly, regardless of the platform and device type. This framework also supports web and desktop by default.
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.
Ionic mimics the look and feel of native applications. With ready-made components and libraries, it’s enough if you know your way around web development to put together and test a mobile prototype.
Angular, Vue, or React - Ionic can be used with any type of frontend framework. You can also code in JavaScript, resigning from using a frontend technology altogether.
Ionic is perfect if you already have a working web environment, and you want to bring existing libraries, components, and user flows into a mobile environment. That’s why this technology is a favorite of brands with a significant online presence and a large user base.

See how our clients created great apps with our help.


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.
