The subscription-based thrills of Last.fm open up a world of music streaming on your mobile. You have to "buy in" to the odd Last.fm way of organizing things and suggesting new music, but if you're easily led and not restricted by bandwidth it's a superb tool.
22. Google Maps Navigation
An absolute must-get. As long as you have Android 1.6 or above, the latest update to Google Maps introduces turn-by-turn voice navigation, simultaneously devastating the satnav industry while boosting the in-car dashboard dock/charger accessory scene. Route calculations are done at the outset of your trip, minimizing data transfer en route and keeping you on target even when the GPS signal drops. It's amazing, it works, and it's free.
23. Catch Notes
A simple note-taking tool, Catch Notes lets you sync those disjointed, late night thoughts you have together into one huge, incoherent database. If you have a Snaptic account you're able to sync the Android app with that, too. Or, you can simply log in with your Google details for instant mobile jotting. Once written, notes may also be pinned to the home screen, creating a little post-it note-style reminder icon.
Astrid describes itself as an "open source" task list, which includes syncing support with rememberthemilk.com for the ultimate in minutiae management. You set a list of tasks and are then able to order them according to their importance - also setting off a timer to see precisely how long you've wasted on Twitter instead of doing the job at hand. It's basically the world's most complex and in-depth personal to do list, which, if used correctly, will consume more time than the tasks themselves. Ideal for expert-level procrastinators.
Skifta is the first software tool to be granted DLNA certification, meaning it turns your Android phone into an official DLNA device. This in turn means streaming all of your household media to your phone, and beaming your phone videos to your TV. Seems a little buggy at the moment, but there are plenty of updates arriving all the time. Requires Android 2.2 or higher.
Amazon recently launched an official Android app, replacing its reliance on a mobile web store. The app's very simple and fast to use, and even includes full shopping cart features with Amazon's one-click system once you've signed in with your usual account details.
27. Meebo IM
If you like to pass the time exchanging smiley faces and abbreviations with your friends through instant messaging apps, you should get a copy of Meebo IM. It's an instant messaging aggregator, incorporating AIM, MSN, Yahoo, MySpace, Facebook, good old ICQ and more, serving everything up in one convenient interface. Typing in all your logins and passwords for everything is the only, very temporary, inconvenience.
If you're into the slightly last-generation social networking site Delicious, you need to get organized with one of the many third-party Android apps out there that support the bookmarking tool. Such as Beelicious, which, once you've got through the slightly cumbersome initial set-up process, lets you simply send website links to your Delicious account via the Android browser's "Share Page" sub menu.
A star on the Twitter app scene, TweetDeck for Android is one amazing little tool. As well as presenting your timeline, DMs and replies in separate side-by-side panels that you swipe the screen to flip between, it can also pull in Facebook status updates. And mix it all in together. And it does Foursquare. And Buzz.
For those over 21, Mixology provides a fantastic free app for budding bartenders. There are a ton of recipes with a bunch of ingredients to choose from so you can create your very own cocktails. The app even gives you bartending terms, tips and tricks to help you out.
31. Google Reader
Google has brought its RSS feed tool into the app era, launching its Google Reader for Android. It's got some great functionality built in, with support for multiple Google accounts and plenty of thread customization options. You're also able to use the volume rocker to page up and down between messages, which is handy for extra-lazy news assimilation.
32. Amazon Kindle
Amazon's Kindle app is a great e-reader, which is seamlessly linked with your Amazon account. Support for magazines and newspapers is limited at the moment, with only a handful of niche publications in Android-friendly format. But for books it's great, with plenty of screen and text display options to get it looking a way that hurts your eyes the least. Another exciting new way to collect classic novels you'll probably never get around to reading because there's the internet now.
The free version of Endomodo is essential if you're sporty, or even if you just like using a GPS tool to stalk yourself walking around. You select an activity, initiate GPS mode and it'll keep track of you, time you and even whisper robotic words of encouragement at you, before generating a stylish map charting your achievements. A map which you can spam out to social networks to show off the fact that you can ride a bike.
Let your hair down by creating a realistic interpretation of what you hair looks like with Androidify. It's an avatar creator that uses the Android mascot as its base, letting you swap trousers and hats with the swipe of a finger. Results are then sharable via Twitter and the usual social tools. There aren't enough types of beard, though. Please release a Beard Expansion Pack.
35. Kongregate Arcade
Thanks to Android's Flash Player powers, casual gaming portal Kongregate is able to bring a huge number of its internet games to Android. They run in the browser so resolutions can be a bit all over the place, but with more than 300 games to choose from there's bound to be something there for you.
The Google-owned Blogger platform now has a presence in the current decade, thanks to the official Blogger app. It's remarkably simple, supports image uploads and geo-tagging and imports the settings of all blogs associated with your Gmail account. There's no fancy editing the positions of your photos, which just get chucked in at the bottom, but it works.
37. RD Mute
The technically astounding streaming video gaming service has now arrived on Android, with an official OnLive app letting Android users play console titles on their phones and tablets via Wi-Fi. It's best played on devices with big screens, but it'll still run on something as relatively modest as an HTC Desire. On-screen controls are the big trade-off, here - but it will work with OnLive's Bluetooth wireless controller, if you've seriously bought in to the OnLive dream.
39. Google Drive
Google Drive is already a major cloud server site online so it makes sense that you can access your files on the go in a simple, efficient manner. It's a great free app as it syncs everything so you never lose your important docs again, and create new ones if you're not in front of your computer.
Another app that's been out there for a while on Android, the eBay tool has also been updated so much that it's now a credible alternative to the desktop site. A recent update brought the ability to list items direct from the app, while there's a simple PIN system that makes paying for your winnings via PayPal much simpler and less convoluted than it is on the full blown web site.
