One of my favorite apps is called SoundHound. If you're ever watching TV or out shopping and you hear a song that you like but don't know the name of, you just click on the app and it will listen for a few seconds and then tell you the name of the song and who sings it.
I'm still waiting for a Dave's Garden App but I'm not going to hold my breath!
my favs are grocery pal, savings star, Michael's stores, sit or squat (clean bathroom app), amazon, ebay, scanlife, the hess app came in handy with the fuel shortage & power outage.. they listed when the fuel was delivered and how much.. can't forget dropbox.. nice file sharing one
Dropbox is a great app/idea especially if you are a person that works on different computers or devices in different places. I'm constantly adding files while at work so I can access them at home and vice versa and the few times when I've needed a file while I wasn't at work or home it's been a life-saver.
the one thing I found with drop box.. if you drag & drop a file.. it won't copy it.. it moves the original one and does not leave the 1st file there.. you need to copy & paste if you want a backup copy on your computer.. pretty annoying actually
I have a lot of favorites, but sure do wish Daves Garden would get up with the times and do an ipad/ tablet app.
For travel I like Inrix Traffic to see trouble spots ahead on interstates; Around Me to find coffee and restaurants and neat places to see in unfamiliar areas; Rest Area Finder for the obvious reason; Yelp for restaurants etc, Trip Advisor for hotels and restaurant reviews;
Dragon Dictation allows you to speak your email message instead of typing it, and then lets you review it for typos and send it to anyone without ever typing a word.
Directv app lets me record a show on my home tv from anywhere; TV Guide gives me a quick look at what's on, and it syncs to whatever service you have, including just a converter;
HPePrint lets you print from anywhere to your home printer;
IDocs HD free lets you print from Google Docs;
Spider solitaire comes in handy waiting in a doctor's office.
Weather Live is my fav weather app, but I have the other main ones too.
