App for Location and Time based messaging?

Hi all,

I was wondering if anyone here is able to advice me as I have been searching around but cannot find exactly what I need.

I am looking for an app that will allow me to send a automated text messages daily when I reach a certain location but only in the afternoon. I take the same route to and from work everyday and my wife would like to know when I am a certain distance off on the way home but the only apps I have managed to find would send it on the way to and from work so what I need is one that is location and time range based.

Thanks in advanced,
Max
