For those who take Cap Metro but have trouble keeping up with the bus schedules:
Dadnab™ is a text messaging service that plans your trips on city transit. Without web access and don't want to study the schedules? Dadnab tells you which bus or train to take, at which location, at what time.
Dadnab's home page has a neat demo.
(Half a h/t to M1EK; I've been meaning to make this rec for a while, and he just jogged my memory.)
