Piano Dust Buster: When we were kids, forced piano lessons were painful, and we didn't have engaging iPad apps to trick us into practising. This one has games, song guides, and it works with your existing instrument or lets you play on its own keyboard. You'll be tickling the ivories like a pro without even trying. Free.
MonkeyGram: Texting is addictive, and Emojis are fun, but why not make your messages even better with cartoons? This app lets you create animated pictures and send them to your friend through SMS, Twitter, Facebook or email. Free.
Metro Tasks: When your life is frenetic, it's hard to keep track of all the things you have to do. Some people plaster post-its everywhere, others set reminders on their phones. This combines both of those ideas — plus a calendar — in one place. You can organise your schedule and manage tasks in folders and set alerts for all your activities, so you'll never miss a lunch date or a deadline. Or at least, never not be informed when you're missing one. $7.49.
Trippy: Now that winter is well underway, you might be ready for a holiday somewhere nice and warm. Find inspiration for your plans in this app, which gives you a collection of beautiful travel photos from places all over the world that you can view on a map. Free.
