Favorite Apps

[sherryinutah]

I recently traded my "dumb" phone in on a smartphone.  That being said, I'm curious about the different apps people use and why they use them.

My smartphone is an Android.

I decided to download a Costa Vida App.  Costa Vida is fast food/quality food and offers Mexican entrees and desserts.  I spend time and money at that place on a regular basis so I like their rewards program.

The Apps are taking the place of the old hard copy punch cards so we really are.....

teaching an old dog a new trick.  That's okay because I love learning. 

Do you have a favorite App?

What is it and why is it your favorite?
