Didnt work anymore, now it does!

Feb. 2015 - Worked great when I first bought it, but now it crashes every time I try to start it.
Im on an iPhone 5 running IOS 8.1.2. Ive tried the obvious stuff like a forced close and reboot, but it continues to crash.
5-3-2015. Traced issue to location services. Made sure app had location services on "always", and had camera on. Did a full power down & reboot, and it works again.
