New Weather App

A friend suggested I sign up for geo-txt.com. You put in your cell phone number and they text you back the weather where you are. I was wondering how this is possible? Thanks for any info.

i like it

Sound intrusting can you give full details about the app please

For checking weather I prefer to use my stock weather app, it updates itself and shows me weather of all my desired location, even the predicted forecast of upcoming days too.
