Web Apps Compared to VoltBuilder Apps
AppStudio apps can be deployed two different ways: as Web Apps or compiled using VoltBuilder or Cordova into native apps. Web Apps are loaded by the browser and can be saved to the Home screen. VoltBuilder and Cordova apps are full native apps, able to be submitted to app stores.
There are two ways to make native apps. VoltBuilder option is easy to use and the one we primarily are dealing with here. Cordova CLI is much more complex, but provides additional features. Check out our tutorials for iOS and Android.
