To test the app you will need to have an iPhone. We will release an Android app later down the road.
Once entered into the test group, you should receive an email from Testflight inviting you to participate in the test for the Plunk App. Be sure to check your Spam folder if you don't see it by the end of the day. We recommend you download TestFlight ahead of time to make the installation process faster.
Once you sign into Testflight with your Apple account, you will see a Plunk App icon with the "Install" button. Press that button, and you are good to go! You should find the app installed on your phone like any other app
