2. Touch Mouse – Free
Your iPhone can also act as a wireless touchpad and keyboard for your PC or Mac, enabling you to control it from any room in the house – so Touch Mouse is perfect if it's hooked up to your TV in another room, for example.
3. Handy iLevel – Free
Now, where did you put that spirit level? Don't worry about it – Handy iLevel turns your iPod into the perfect companion for putting up shelves. Just calibrate it on a flat surface and you're good to go. Upgrade to Handy iCarpenter for £2.39 to get four more useful tools: plumb bob, bubble level, ruler and protractor.
4. Did I Close The Door? - 59p
Did I Close The Door? may be designed for those people who keep forgetting to lock their doors, but renaming one of the presets to "Gas cooker" or "Security light" enables you to compile a checklist of important things to do before you head off to bed – or Benidorm for a week.
5. iSat – Free
Having trouble pointing your satellite dish to the correct satellite? Set your location in iSat using the "i" button, then pick your chosen satellite from the dozens listed (spanning the entire globe), and you'll be told how to align your dish accordingly.
6. PrinterShare – Free
Print photos, web pages, contacts or the contents of your iPhone's clipboard on your PC's printer with the free PrinterShare app. You'll need to sign up for a free PrinterShare account at www.printershare.com, plus download the server software for your PC or Mac. Once done, you can set up print jobs from anywhere on the internet for processing automatically or when you get home.
7. Cleartune – Chromatic Tuner - £2.39

8. Tree-to-Go – Free
If you're into your family history, Tree-to-Go is a must. It links in with your free online tree at Ancestry.co.uk – not only can you show off your tree to family, you can add or edit entries, plus upload photos from your iPhone too. Perfect should you find yourself in a dusty records office following a promising lead.

Torch might feel gimmicky, but you'll be glad you installed it the next time you're plunged into darkness and left scrabbling around for the trip switch or fuse box.
