Why Flutter is the right choice?


01 Quick app development with smaller budget

Flutter is a proposition for those who want to release a product as soon as possible and their budget is limited. Why? Instead of building two native apps, you just stick with one. This means engaging smaller team of specialists and less time needed for development

02 Hot reload

We can see all the changes in UI right after the implementation. Hot reload feature makes it possible. At the same time, it significantly optimizes development process. The results? Errors are detected at an early stage, many solutions can be quickly tested and we are able to make better decisions that impact UX.

03 Shorter development time

If a new feature has to be added quickly, Flutter is also at our service. Even if the app is a native one. All we need to do is to create one component in Flutter that can be added to iOS or Android app. Unless this specific feature relies on system components, there is no need to waste time on the development of two native solutions.

Flutter vs native app

Even though Flutter has many advantages, it will not always be the best choice. In some cases native apps turn out to be more useful. They also give us more opportunities to adjust products to user needs.

When it is better to choose native technologies over cross-platform ones?


  • you want to release the app as soon as possible
  • your budget is limited
  • design of the app has to be identical on iOS and Android.


  • the less memory it takes, the better
  • the project requires many integrations with system components
  • you need 100% efficient product working in the offline mode.
