Thanks for the recommendations. I don't have iTunes but those apps sound as if they could be very handy.
I am not very tech-savvy. Just got Smartphones 2 months ago. I like the following free apps: Scout, Gas Buddy, Google Earth/Sky Map, Swiss Army Knife.
Came across Lifeline 360- it's a tracking program. It will track another smartphone. You can set it up tell you when someone leaves and arrives at a certain location,(home, school, work, etc.). It is peace of mind, with latchkey kids.
I also have used, Red Laser-it's one of many UPC scanner apps. I used it last week at Home Depot-Lowe's had the same thing on sale, and I used the app to price match, saved $7!
