Which programming language is the best for cross-platform?

Which is best: native or cross-platform development?

When Flutter fits

  • When you want to target mobile users of both iOS and Android.
  • The project budget is small (as a bonus, below you’ll find the estimates for 2 real apps that our developers have built lately).
  • The functionality and interface of the application are not complicated and, in principle, it can be implemented as a web application with an adaptive layout for mobile phones, but you want, for example, to use push notifications.
  • Application size and super high performance are not important. The application does not use or is used to a minimum of the device’s features, such as Bluetooth, camera, sensors (temperature, pressure, gyroscope, etc.).

When Flutter doesn’t fit

  • If it’s necessary to get the most out of your app’s performance for such applications as games, AR / VR apps.
  • If you need an app of minimal size.
  • In case your app is planned to address the mobile’s functions (already mentioned above).
  • Applications with a complex interface and non-standard UI components. Security-critical applications where data encryption or biometrics is used.

Cross-platform app development cost. How much does it cost to develop a cross-platform app?

Application for sport events

  • login process;
  • possibility to join command using specific code;
  • home screen with standings, navigation bar and short info about the next match;
  • screen with ladders and fixtures;
  • screen with team management and a possibility to add new teammate;
  • capability to change team;
  • profile with all the necessary info (name, last name, phone number, email, etc.) with the capability to adjust it;
  • lineup screen for defining command composition on the upcoming match; project building and deployment in app stores.

Content aggregator app

  • Tutorial screen (swipeable instructions on the first launch of the app).
  • Four navigable bottom tabs (three for different feed categories, one for useful links).
  • Settings page (data sources for the feeds can be configured from here).
  • A feed can contain posts with text, images, videos from different sources.
  • Instagram-like video playing for feed video entries (autoplay, muted by default, after the first tap unmuted until restart of the app — the behavior can be configured on the settings screen).
  • Filtering the feed by a specific data source.
  • Sorting feed by different keys.
  • Pull-down-to-refresh and “endless” feed loading.
  • Post details page.
  • Sharing the posts, sharing social media accounts of the authors of the posts.
