Cool Android Apps

I've recently upgraded my phone and got my first smart phone! The phone itself isn't anything fancy, still fairly basic when it comes to smart phones I suppose, but considering that this is my first smart phone, I decided it might be useful for others to know what apps I use... so what I consider the best, is:

E-book reader: Amazon Kindle  - this is an obvious choice for ebook readers as so many people use kindles and it can be placed on so many different devices.

Antivirus: avast! Mobile Security - Smart phones are being a prime target for virus now because they can contain so much personal data, tied to so many accounts, and usually the security is minimal on them. Also, Avast! has the benefit of tracking your phone too.

Tracking your phone: Prey - Prey is an amazing tracking program, I've used Prey in the past and really love and trust the program. It's free up to 3 devices and have it installed on my laptop and my phone.

Games: Chess Free, 100 rooms, Super Sudoku

Storage: (Google) Drive, Dropbox 

What is this?  Images: Goggles  - This is an awesome program! It allows you to take a picture of, lets say a piece of artwork, then it scans it and returns the results. I scanned a piece of artwork by Salvador Dali, and it returned the artworks name (Die Drei Sphinx Von Bikini), the price of a poster of it and where to buy it (art.com, etc), similar images, and even a book that used the artwork on it's cover (Qualitative Research in Health: An Introduction by Carol Grbich)

                       Audio: SoundHound - Also an awesome program, have you ever listened to the radio or have the humm of a song stuck in your head? This program will tell you the name of the song, show the lyrics, option to buy, bookmark, share, search for it on youtube, similar artists, songs appearances!  That's more than I can think of regarding one song! It's incredible!

Knowledge dump: TED - TED is a great source of knowledge in short audio/video clips. Everything from medical & transportation to science and engineering, from kids to the elderly talking, sharing, exposing, experiencing, training. It's a very humbling experience

Looking at the stars: Google sky map

Freeing up space: History Eraser

Saving battery life:  JuiceDefender - This program has given my phone an extra day of life, just by installing it, I've seen no changes in my usage, just an extra day. And one day may not seem like much, but when I go from 2 days to 3 days charging it's nice, especially since my old phone used to go a week between charges

Personal finance: Mint.com

Checking prices: (Amazon) PriceCheck

Scanner: CamScanner - cool program to scan documents with your phone, and it really looks like it was scanned! From there you can email, fax, share, absolutely wonderful!

Are there any apps out there that you can't live without?
