Just got a Wakeye and really like how it tracks and the speed based automatic record start/stop, but the video quality is so poor using my iPhone 6s that it's not really usable.
I've seen the discussions about turning stabilization off and increasing FPS, but there seems to be a bug that prevents anything other than 30 FPS on the 6s. Either that, or I don't know how to use the setting. I assume you would click on 30fps to change the setting just like you click on the speedo to change the auto recording speed. When I click on 30fps, it goes grey like it's going to give you options, but no options appear. Sometimes I get a message saying your videos will be stored to the gallery when I click on 30fps. My guess is that the app is checking which version of iPhone hardware is in use, to decide which FPS settings are supported and that logic is not working correctly on the 6s.
