Best free Android apps: 21-30 | News | TechRadar

21. 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.

22. gvSIG Mini Maps

gvSIG Mini Maps is an incredibly comprehensive mapping tool which combines major online maps including Google, Bing, Open Street Map and more, which will win UK fans for one huge reason alone - it supports the official and recently open-sourced Ordnance Survey data. This means you're never more than a post code search away from seeing where you are in OS-level detail, which offers much more in the way of accurate local data than other map tools provide.

23. Astrid

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 in 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.

24. Shareprice

Shareprice uses your login from financial site www.iii.co.uk to offer live share price updates on your Android phone. Watch your nest-egg lose 50 per cent in value every three weeks during the latest trans-global financial crisis, live! It's ideal for users with share values so low they have to be checked in private, to ensure their partner doesn't see exactly how much money has disappeared into some notional financial black hole.

25. Skifta

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.

26. Dropbox

The Android version of the insanely popular stuff-syncing app has arrived, and while Dropbox is a little lacking in the sort of fancy auto-syncing options many were hoping for, it still works as expected. Files have to be specifically downloaded to your phone to be edited or shared, which is not quite the automated dream offered by the desktop tools, but it's still Dropbox on Android. Six months ago that was a distant, crazy fantasy.

27. London Tube Status

Reduce the misery of being told you've just missed a train and it's a 14-minute wait until the next one with London Tube Status, which combines travel status updates and live departure times. It also includes a home screen widget that shows your favourite (or at least your most used) platform departures, making it easy to check how much you've just missed the next one by while tearing down the escalators.

28. Amazon UK

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.

29. Meebo IM

If you like to pass the time exchanging smiley faces and abbreviations with your friends through instant messaging apps, you ought to 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.

30. Beelicious

If you're into the slightly last-generation social networking site Delicious, you ought to get yourself organised 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.
