If you have a Samsung GS4, weather station apps like these are pretty nice:Reply
They use the sensors that are built in to the phone.
The card keyring app is an interesting idea. And not to diminish the value of the other apps showcased, but most things in them are things you could just google; the shopping card membership idea is one of the few I'd actually call a user utility app.Reply
