Flutter app development

Cost-effective solution for creating high-quality mobile apps.

Maciek is programming

Flutter is a technology that allows you to reduce the development time and cost of Android and iOS applications by writing only one code for both platforms at the same time.

At FiveDotTwelve, we have been using Flutter in projects since 2019. We believe it is one of the most innovative and efficient mobile app development frameworks available.

It’s a great solution for those who want to release the app as fast as possible, for example to test the business idea and get feedback for the product.

What we can do for you

Flutter app development

We develop mobile apps using Flutter which enable to create both Android and iOS apps at the same time. As it speeds up the development process, you can get your product to market much faster.

Flutter app design

We design apps from the scratch or improve existing interfaces to provide a great look and user experience. Combining them is important as it shapes the whole interaction with the product.

Benefits of Flutter for your business

Faster time-to-market

Developing iOS and Android apps separately can be a time-consuming and costly endeavor for business owners. But Flutter is designed to accelerate the coding process by providing pre-built widgets and requiring less code to be written, so you get two apps much faster.

In cooperation with Onoco, we were able to deliver the project 10% earlier than estimated, thanks to Flutter.

Cost-effective solution

Flutter allows developers to build applications for both iOS and Android platforms with just one codebase which is much cheaper than building those apps separately with two dedicated developer teams. Combining it with the Time and Material pricing model used for software development projects means that you only pay for the time spent on each task, makes it a cost-effective option for businesses.

Reaching a wide audience

With Flutter you get an app for both Android and iOS at the same time, so you can show it to all of the users from both platforms. No need to choose between building an Android or iOS version first, especially if you have a limited budget.

Great app performance

Flutter apps have excellent performance capabilities, as the widgets incorporate all platform differences, such as scrolling, navigation, icons, and fonts, and are compiled to native ARM machine code using Dart's native compilers. As a result, there is no difference in performance between native and Flutter apps.

They love working on our projects, and they enjoy what they do. Most developers don't like to work on other people's code but FiveDotTwelve has been very open to that. Thanks to them, we didn't have to rewrite the app's code. They're also timely, which is why we have a very good relationship.
