With the simulator, you can simulate the look, feel, and behavior of the app in a realistic manner. You can use the device simulator for debugging and for quick testing without deploying to multiple devices. Saved changes are automatically synchronized to the simulator.
In the AppBuilder Windows client, the AppBuilder extension for Visual Studio, and the AppBuilder command-line interface, the device simulator runs as a stand-alone application. In the AppBuilder in-browser client, the device simulator is a module.
To avoid the limitations in the simulator, run your app on a physical device.
When possible, run your app on a physical device in addition to running it in the simulator. Running on device provides the most accurate test results but running in the simulator is essential for debugging.
