Invy is a date picker app, meaning that it lets you suggest suitable dates for an event. Send an invite and your friends can respond using the app or the Invy website. A decent idea but it seems more complicated than sorting something out needs to be!

This interactive music app features 3 favourite children's songs - London Bridge, Evening Song and Old McDonald. Aimed at those between 2 and 6 years of age, there are over one hundred interactive elements for young players to explore. It could be great with some more songs to choose from.

Smartshift Lockscreen is a fantastic lockscreen app for your Android phone. Showing traffic updates, video collection, social networking statuses and switching itself to silent when needed, the app knows where you are and tweaks your settings accordingly. It's mind-blowing! With endless customisation options themes, it will fit your life perfectly.

Evi is an artificial intelligence app designed to help you find what you need. Combining voice and text input, Evi is supposed to be smarter than a search engine. Sadly, the app isn't quite living up to its potential (yet), doesn't recognise some inputs and answers with links which can be found on Google or similar.

Pirate Mysteries is a cool hidden-object game for Android. During your quest to save your father, work your way through exotic islands, solving riddles, finding hidden objects and completing the 10 mini games. It's pretty sweet! Possibly the best hidden-object mobile game I've tried.

Just Notepad for Android is an amazingly handy and useful tool. Note things you need to remember - phone numbers, addresses, to-do lists, and store them by simply opening the app, typing or pasting the text and then shutting it down again. Simple but great!

Fans of the Talking...series of apps, here's a new one for your collection! Santa's in his grotto and expecting a visit from a normal kid. Unfortunately, here comes Ginger, a mischievous kitten who will pull his beard, set him on fire and kick his shins!

Based on the all-new Bejeweled 3, this game is a great successor to the very popular Bejeweled 2. You can play in each of 3 modes - Classic, Zen and the more action-packed Diamond Mine. One thing to note is that Blitz is now a seperate app so Facebookers will need both!

World of Goo is a fab game - drop blobs of goo to build stuff in an array of mysterious, but really cool, levels. The goos can move, talk and squirm and you can discover new gooey friends as you progress. More fun than you ever thought goo could be!

iTether is a very clever app which allows you to connect your PC or Mac to your phone for internet use. As long as you have a data connection on your phone, you can now use your notebook wherever you are. It's a little expensive but well worth it!
