Preview and Test
^^^^^^^^^^^^^^^^

*Please note that Preview Feature currently only works with Android and iOS implementations.*

Once your Feature Flag code has been implemented, you’re ready to test! Simply
press the "Test Feature" button and you’ll see a list of devices to select from.
By default, only developer builds or debug signed builds of your app can connect
with Apptimize. Make sure to use one of these builds by asking your developer
when trying to create an experiment.

If you can only use a release/production build, i.e., an app downloaded from the App Store or Play Store, you can pair using the following method.


If you’re having trouble connecting your app, please see our `troubleshooting
page <https://faq.apptimize.com/>`_ for more details.

Once your device is connected, you can preview the user experience when the
feature flag is "on".
