Favorite apps

My old cell phone was a fine phone.  I used it for calls, texting and photos.  It had web access, but that was extremely cumbersome so I didn't use that feature.
 
I got an iPhone for Christmas, and I thought it would be nice for those who have phones that can download apps to share what they have & what they like.
 
These below are all free - most come in paid, ad-free versions as well, but I only use the free ones:
 
MapMyRun - I love this!  I have an otterbox defender that comes with a clip so I can easily carry my phone when I run - when I run with Maggie, I want both hands free.  It shows the map of my route, calculates miles, pace, calories burned and when I run the same route, keeps track of my best times.  It has other features I've not explored yet, but I really like it.
Words with Friends - 'nuff said.  Wanna play?
Flashlight - I've only used this a couple of times, and I'm sure it uses up loads of battery power when it's on, but it's nice for unlocking doors at night or for quick lighting needs.
TVGuide - it doesn't show all the channels, but it's easy to find what's on the main stations and to get summaries of each show so I can tell if it's a rerun and if I've seen it.  
WeatherUnderground  - quick local weather information - useful in the morning when you don't want to wait for the tv meteorologist.
Shazam - to identify and keep track of songs on the radio, in case I want to purchase them.
Kindle  - I have this, and haven't really used it much.  It tracks with my Kindle so I can read the same books.  
 
Not sure about:
Pandora.  The first time I turned this app on, I couldn't stop it, even when I exited the app it kept playing.  I need to check to see if that bug has been worked out.
Pocket Pond.  Fun at first, but kind of boring now.
