Android App List

Ok, I've been meaning to do this for a while. I've promised it to a bunch of people but it has just taken forever to actually put this list together. This is my first shot at reviewing stuff, so be gentle with the constructive criticism.
I'm going to break this down into free and paid. Almost any paid app has some form of free version. Sometimes that's limited functionality, sometimes it's a trial period, but it's always a good idea to give it a shot before you pay for it. There is only about a fifteen minute window to get a refund if a paid app doesn't do what you would like it to, and that really isn't enough time to see if you like an app enough to pay for it.
Another point, all of the apps that I mention came from the Google Android Market. That's not to say that the Amazon App Store is any better or worse, I just prefer the Market.

Free Apps:

Evernote - A note taking app that can sync across almost any platform, including your PC or IOS device. It wasn't immediately obvious what I would use this for, but it has rapidly become indispensable for keeping track of things on my Nook Color (Rooted), computer and phone.

Mint - This app collects all of your financial information, including credit card accounts, bank accounts, and loans. It has handy payment reminders, balance monitoring, and a lot of interesting tips on making your money work for you. 

Nook - Barnes & Noble makes their e-book app available on most platforms. You can read on your Nook, tablet, phone or computer and it will keep your place synced on all of them. You can purchase media on any of the platforms and download it to any of them. Animated page turns are a plus.

Kindle - About the same as the Nook app, but from Amazon. Not quite as pretty, but fully functional and a bigger library.

Angry birds - I won't plug any other games, but this is that game that you have to try.

OI shopping - This is a handy shopping list app. It has a lot of functionality like prices, quantity and brand. It can be used for any list, but it doesn't sync to a server so it is kind of limited.

Google Voice - This does require signing up for an account on google.com/voice. You're already in the googleverse though, so take the plunge. This app provides visual voicemail, wifi calling and free SMS. All of this stuff can be accessed from a computer as well as your phone.

Google Music - Another great service from the folks at Google. It starts by going to google.com/music and uploading all of your music. After it's in the cloud, you can use this app to stream your music anywhere that you have a data connection. You can also make a large part of it available offline (great for poor data coverage areas. 

Google Listen - This is a podcast management app. You can subscribe directly from the app or from google.com/reader. It only does audio, but it does a pretty good job of automatically downloading the newest episode of your podcasts and dumping them after you listen.

Astrid - This is a great to-do list manager. You can have many separate lists and sync them all with Astrid's server or Google Tasks. It also offers a lot of sharing and collaboration options.

Keeper - Passwords, we all need them and it's a pain to keep track of them. Keeper allows you to save them behind 256 bit AES encryption. It includes the option to create random passwords that are really strong and a place to save them so that you don't have to remember them. This app also has a paid service that will let you sync your data across platforms, as well as backing up your data into the cloud. (I do subscribe to the paid service, but it isn't necessary)

Barcode Scanner - This is mostly a plug in, letting you scan barcodes with your camera. Handy from time to time.

Chrome to Phone - Only useful if you use the Chrome browser, also requires an extension on Chrome. This is where Jack Bauer gets his stuff...you can push a webpage from a PC to your phone or tablet. Pretty handy for taking things with you.

Documents to go - The most intuitive office suite that I've tried. The free version allows viewing all Office file formats and PDF. For editing, you'll have to upgrade to the paid version. (Another app that I paid for)

Dropbox - Another app that requires setting up an account somewhere. Start yourself an account on dropbox .com and you'll be able to keep any file that you want synced across any platform. Very handy for those that might be working from anywhere. 

Google Maps - At one time this was part of the stock Android install. If it didn't come on your device, download it now. It lets you search for anything based on location, and has a turn-by-turn navigation function. This seems to be at least as good as most of the paid apps on IOS that do something similar.

Netflix - Obviously this is only useful if you are a Netflix subscriber, but if you are then you can get your movies and TV shows anywhere that you have a data connection.

Overdrive - This is a way to download ebooks from your library directly to your Android device. It's the same content that you would get if you downloaded it to your computer then used third party software to transfer it to your phone or tablet. It is only for getting stuff from your library though, don't expect it to do more.

Pandora - I don't know how long their business model will hold out, but I'm going to enjoy it while I can. A great tool for music discovery, it is really smart about finding music that is similar to what you give a thumbs up.

Shazam - Ever heard a song on the radio that you wanted, but you didn't know who it was? This app uses your phone's microphone to listen for digital tags to recognize a song. It then offers to search for it on Amazon, Youtube and I think the Android Market.

Paid Apps:

I haven't paid for may apps, so this list is much smaller. You can get a paid app for free on the Amazon App Store every day. Sometimes it's a great one (Documents To Go offered their paid version once), sometimes it's less great.

Business calendar - The basic calendar is ok, but this one ramps it up quite a bit. The widget is clean and neat, and it will sync with any and all calendars that you use.

Tweetcaster pro - The new Twitter app is pretty cool, but this one beats it up. It offers multiple account support, and it does a better job managing lists.

Beautiful widgets - The name says it all. If you don't have an HTC with Sense UI, then this package is a gorgeous upgrade for weather widgets.

Documents to go (Full Key) - The full key unlocks the ability to create new files and edit current ones. Doing this on a touchscreen is a little less intuitive than using a keyboard, but this app does a great job of keeping it clean while you're editing.

Keeper Subscription - Subscribing lets you take advantage of the backup and sync options. I enjoy being able to get to my passwords on my PC, as well as generating random passwords while using my PC to sign up for new accounts and then having it automatically saved to my phone. 

This isn't a comprehensive list, just the must haves. I'm sure that I've left something out that I'll have to add in later. As the new versions of Android roll out I'm sure that I'll have to update this, and I'd be glad to hear of any that I've missed.
