If you’re a fan of live streaming video on your iPhone, there are a few things you need to know before starting. First and foremost, Periscope is a free app that works on both the iPhone and iPad. Second, make sure that your phone is up to date with the latest security patches. Third, be sure to have an account with Periscope – this will allow you to stream videos from your phone and also access exclusive features like live chat and private messages. Finally, be sure to have a good internet connection – without it, streaming can take a bit longer than expected.
