After you complete testing using the device emulator and are satisfied with your app's quality, the next step is to test the app using the actual device(s) it will support. Before you push your app to the server, log into your Intel XDK account.
For the latest information, please read the instructions on the TEST tab to sync your app with the testing server.
For each mobile device:
Download the Intel App Preview app from the appropriate app store(s) and install it.
Launch the Intel App Preview app and log into your Intel XDK account.
Launch and test your app.

Additional ways of testing include:
Use a remote debugger (such as Weinre) that accesses the app running on the target device. See the instructions on the TEST tab.
On Android devices, use the DEBUG tab to access the app running remotely on the target device. See the instructions on that tab.
Use the simulator or emulator provided with each respective SDK. You use the SDK simulator or emulator on your development system, without access to a real device.
