Good overall app, great interface

Love the retro look of the interface, which becomes very intuitive to use. I only wish it had a "hold" function to freeze the readings (such as when using in incidence mode and then returning to the camera). Some users reported the app crashing, but I have had no issues (it may be primarily people using it on an iPod touch, which I dont believe has a camera as sensitive as an iPhone 4/5)
