I consider myself relatively intelligent but can anyone give me a clue what can be done with a black and white triangle that when tapped swiped shook or spoken to ( please help Siri) does nothing but gives me a reading in either inches or centimetres for nothing that I've measured! I know it was free but that's the only positive.

Made me laugh

This really is so bad it is good. It really does do nothing. You could "build" it yourself with a photo of a ruler. Deserves a special prize.


Of no use! One star, only because I can't give it none!!
