The Next Web’s Paul Sawers:

A referee may use his/her notepad for anything – noting down substitutions, red/yellow cards or any other on-field incident. Now, European startup Siine has launched Referee Pro, a smartphone app that will see the first ever football match kick off today with a professional match official using his mobile phone to record events, as well as dishing out yellow and red cards.

Yeah, it’s just a “smartphone” app… only cool if  it runs on iOS. Just kidding. This is really fascinating. I wonder what ‘problem’ it solves.
