Native Navigation

The navigation paradigms on iOS and Android are different. On iOS you have a swipe-back gesture to navigate back in a navigation stack. On Android you usually use a navigation drawer that slides in from the left side. Felgo Apps abstracts these navigation differences and allows you to use just a single Navigation component, that works cross-platform.

Felgo Plugins

Mobile Plugins

With Felgo, you can use many 3rd party services with just a few lines of code.

All of these plugins work cross-platform, which allows you to maintain a single code base.

import QtQuick 2.0
import QtQuick.Controls 2.0
import FelgoPlugins 2.0

ApplicationWindow {

  OneSignal {
    appId: "<ONESIGNAL-APP-ID>"
    onNotificationReceived: {
      console.debug("Received push: ", message)
    }
  }
}

Push Notification QML Example

Responsive Design

Did you optimize your app for smartphone AND tablet already? This can be a tricky challenge, because with wider screens you can show more information in your app and make the user experience even better. If you optimize for smartphone only, you’re reducing your potential for success.

With Felgo, you don’t need to change your existing code but can use the same source code for phones & tablets. You get a “tablet view” with a navigation page on the left and the actual content page on the right automatically when the screen gets bigger.

Responsive design

Animations Made Easy

Creating complex animations in your app has never been easier. Make use of Felgos powerful animation system, to create stunning animated UIs.

Felgo apps are native, for top performance and smooth animations.

Animations made easy

Simulate Platform at Runtime

Speed up your development and testing time with the live platform simulation feature by Felgo: Simulate any platform and change it at runtime on your PC!

The native components and navigation automatically change their style to the new platform. This allows you to rapidly test how your app looks like on iOS and Android on your Desktop PC. The start time of your app goes from 1-2 minutes, down to just a few seconds!
