Doesn't work right – EnLighten Review

Interesting idea, but it never worked for me. It would start counting down at a red light, but them with about 5 sec left the countdown would disappear and it would just show a red circle with a car in the middle. Never had a chime to let me know the light was about to turn green. Also, it allows your phone to auto lock, then rendering the app useless. If I have to keep paying attention to my phone so that it doesn't auto lock then that defeats the entire purpose of the app.
