TextNow - We have the first iPhone and our plan doesn't include unlimited texting. This free app lets me text for free (unlimited). My text-crazy friends love me now. LOL
Flashlight - Turns my phone into a flashlight and has fancy colors to amuse children.
Compass - Turns my phone into a compass. Mostly for fun, but also has an educational component. (I'm a Girl Scout co-leader and camping/outdoors stuff is my fave.)
Remote - Turns my phone into a remote to control the laptop under the TV. We use the laptop to watch a few TV shows (hulu and other) and movies and listen to our music library. Since the laptop is physically attached to several cables and tucked back into the TV console, it is challenging to use the keyboard on it. This app has made it so much easier!!!
RulerPlus - Gives me a ruler while I am out and about. Mostly helpful when we are deep into home improvement projects and I need to measure smaller things in stores before purchasing.
Scribble Lite - Entertainment for my DD, but also therapeutic for me. Scribbling is relaxing and no paper or pencil required.
tideApp - We live near the coast. High tide is best for water play (boogie boarding, etc) and low tide is best for beach walking. Nice to know in advance!
Voice Memos - So handy!!!!!! It syncs to my computer and shows up in iTunes, which reminds me to listen when I am home. I typically record notes while I am out and about. So much faster than typing in a note program!
Plus a bunch of apps that make browsing the web easier on a phone. Safari itself is rather cumbersome on a phone. Amazon, Facebook, Tapatalk, YouTube, the Weather Channel, and our banks all have apps that work much better than Safari.
