I Must Be Going transit widget

útil artilugio dice cuando sale de su casa los próximos autobús / tren, como un reloj.

This app comes with a widget - it tells what time you need to set off to catch the transport service you need. It works everywhere where Google Map works.

It watches the bus/train schedule, and judging by your location and frequent destination, tells in how many minutes to catch which bus/train home. It updates continuously in the background.

If you put the widget on the lock screen then you will know how long you can stay without unlocking or fiddling with your phone - great if you are in the middle of a conversation.
