Not worth a dollar
I tried to use this last night in Iceland. Unless the lights are bright enough (which apparently is rare) it wont pick up anything and will be black. I couldnt get it to work, so I used my own eyes to look, which was much more rewarding! Wouldnt pay for the app, any digital camera probably has enough settings to take better pictures.
