FMX is a cloud-based software, meaning you can access it from any device with an internet connection. This is also referred to as a Web App. So, what's the difference between a native app and a web app?
A native app is essentially for one particular mobile device platform and it can be installed directly onto the particular devices itself. Users of native apps usually download them via app stores like the Apple App Store and the Google Play store.
A web app, such as FMX, is an Internet-enabled app that can be accessible via desktop Web browser, or even mobile device's Web browser. They do not need to be downloaded onto mobile devices in order to access! All you need is an internet connection, and viola! You're connected!
Web app development is more typical to show adjustable graphical user interface between various devices, whether app viewed on a desktop, a smartphone, a tablet or other devices, it should have a coherent design that works for the every size of screens, and remains all familiar to the user on all kind of devices.
