Do you happen to have a GoPro that does not have a screen on the back, but you do have an iPhone with the GoPro app on it? Well this will allow you to mount your iPhone right behind your GoPro and use it as the screen. At the moment, I only have the version for the iPhone 4s upload. But I am currently working on a version for the iPhone 5, 6, and 6 plus as well. So stayed tuned for more updates along the way! UPDATE: 9/6/15 Uploaded the versions for the iPhone 5, iPhone 6 and iPhone 6+UPDATE: 10/29/15 No longer just for iPhones, just uploaded a version for the Samsung S5. If there are any other versions you would like to see included, don't hesitate to ask and I will see what I can do!
