The video does not scale correctly onto an iPhone 6 plus, so there are thick black bands above and beside the video for every camera. There is no way to fix it. The problem also seems to make the picture quality poor on the iPhone 6 plus.
On iPad the app seems to work quite well.
Please fix the app for the iPhone 6 plus FLIR!
