it works fine people, you stand in front of your mates camera that can expose for a few seconds. input the words you want and wave the phone from your right to left while they take the pic. do it in the dark! Timing can be tricky. a beep before it starts to display would help a lot.
Works great! People need to read the instructions. Please make it an option to disable the hardware buttons backlight.
Great idea BUT Really great idea and good graphics. But the implementation is not so nice. Sluggish.
Not the best app for this, very basic!
Nice new possibilities for your light paintings. Great idea and works better than expected!
