We turn your idea into a beautiful mobile application. At LeanCode, we've developed 30+ custom mobile apps for our clients.

Mobile solutions we specialize in

After coming up with an online business idea, the next vital step is choosing the best mobile solution. Sometimes it's a real hassle for our clients to find out what type of app-building approach will connect the audience with the brand in the best possible way. LeanCode takes this burden off your shoulders.

We specialize in cross-platform app development, and we believe it's the best solution for most cases.

Cross-platform development allows targeting audiences on different platforms and remaining an excellent performance of a mobile application. It significantly shortens app development time and lowers the costs due to the possibility of writing the code once and reusing it for each platform (iOS and Android).

Using cross-platform frameworks such as Flutter or React Native also gives you a chance to create a user experience and interface that hooks the audience on the app.

Mobile app technologies we use

We specialize in developing mobile apps in Flutter.

Flutter is the newest cross-platform framework based on Dart language that enables building applications for mobile devices (iOS & Android) and desktop (Mac & PC), and web browsers from the same codebase.

It provides excellent performance and user experience on both platforms as well as increases time to market significantly.

Why is Flutter great for mobile app development?

Flutter is a stable solution that allows building great products while saving on the budget:

1. There are already more than 150K apps developed in Flutter worldwide.

2. It is possible to build the native apps for iOS and Android from one codebase.

3. It is easier to prepare the adjustable screens and complex animations in Flutter.

5. Flutter’s custom widgets provide a wide range of possibilities for creating the app’s visual side.

6. Application is deployable to Web and Desktop alternatives (since Flutter 2.0).

7. It easily integrates with different platforms such as Android, IOS but also Linux, MAC, Windows, and Google Fuchsia applications.

When should you be extra cautious with using Flutter?

You should remember that Flutter is in the first place dedicated to working as a framework for cross-platform mobile applications. Even though with the Flutter 2.0, the coverage of supported interfaces extended to the desktop and web apps, the product owner needs to remember that the Flutter implementation for those new platforms is still in its infancy.

The examples of great apps in Flutter working across all platforms are starting to emerge, and this will be a growing trend. However, an extra caution here, especially for the business-to-consumer cases, is recommended.

You also need to be aware that although Flutter can easily communicate with the native components, it sometimes does not make sense to use Flutter when the business requirements involve only one platform (iOS or Android) as a target development environment.

Besides that, there are some rare cases when the usage of external components and libraries is required yet not supported with Flutter. Over the years, the risk related to those situations is getting lower. However, to investigate those issues, a simple Proof of Concept app is recommended to validate the implementation before committing to the long-term project.

Since the mobile share of human interactions with the digital world took over the desktop in May 2019, mobile apps have become the standard requirement for all modern products.

They are present in both the consumer world and business, enterprise applications.

What makes those mobile apps so powerful is their features. We take care of the implementation of all components necessary for the apps to perform at the edge of current technologies.

We also propose customs mobile app solutions like gamification experience, payment systems, subscription services, and many more. It depends on your business idea and established goals.

We run Product Design Workshop to come up with the best solution and define the scope of work.
