Kieran Gane (Japan)
Phone-based Location Alarm
Have you ever fallen asleep on the train and gone past your stop? It happens all the time in Japan.

So why could we have an alarm function which rings when we get into a station? You set it at the start of your journey and it tells you when to get off, when to change, where to go etc.

Never wake up in train sheds again!

Reward: Free phone and minor credit.
