My mom shared this app with me, and it’s so obvious – turning the camera’s flash into a light – I’m amazed I didn’t think of it before. It also looks funny because it’s so incredibly bright, almost blinding in the dark. But the best phrase is that it gives new meaning to the word – flashlight.

Or, if that annoys you we can go with torch as it is called on the Android app – and in Britain. No such international wordsmithing for the iPhone version. Either way it is incredibly useful to have a light with you at all times.

Enjoy and if you know of better apps – please share.
