Good functionality; cluttered interface

Very nice augmented reality app. Solid functionality. There arent that many out there, because theyre hard to do well. This one is about as reliable as one can expect from machine vision performed locally on the iPhone. It has several cool unique features, like a time (rather than distance) separation, and automatic detection of speed limit signs. I dont seem to have as much trouble with speed limit sign detection as others. Not sure why. Everything works relatively reliably.
Downsides:
1. Not optimized for iPhone 6 Plus screens :(
2. Whats with the mandatory Facebook integration for driving analytics? Id like some, but I will not integrate my driving app with Facebook. This is deeply upsetting and disappointing.
3. There are at least two major features missing:
a) A speed warning based on the last detected sign versus a statically-configured one.
b) Interface customizability. The main screen is cluttered with useless (to me) information which takes up at least 33% of the useful display space. Id prefer either a cleaner screen, or at least to be able to configure what information appears. For instance, playlist controls would be nice.
