Arguably the strongest feature of the iPhone series is the "App Store". Here you really can find an application for just about anything their not kidding. While you will most likely not be interested in 80 percent of them there are certain to be heaps that will not only be useful but some that you will wonder how you ever lived without!

• Torch - how many times have you used your mobile screen light to find something? This simple free app makes the whole screen white, tap anywhere on/off.
• MultiConvert - There are so many conversions here that they have to be listed by category, weight, length, volume etc, just to list the most common. It also includes, shoe size and radioactivity!!
• Yellowpages - why do I still have a pile of these in the corner? Now we just need Whitepages!
• Meet Bubble - a fun spirit level, perfect for making sure that the caravan is level!
• Olivetree Bible - well thoughtout Bible software.
• ShowLoo - Free - uses GPS and Google Maps to show the nearest listed ammenities.

Of course there are games also... for me they are usually puzzle/logic that fill in time waiting in airports etc. Family favourites are

Flight Control - more hours have been lost to this game than all others combined! It all seems so simple but soon becomes quite tricky indeed.

Monopoly - we play this on long drives interstate, it is the same as playing on a board but with out all the little pieces to lose and auto banker. Usually the kids and I play up the front of the truck while mum is sleeping. They talk about what is going on and then I give them instructions when it is my turn. Best $6.00 we spent on the trip from Canberra to Mildura (the Hay Plains rolled by much more quickly ).

Sudoku - Free version. Easy to use hours of puzzling.

GeoDefense - Tower defense at its best. I thought I was going pretty good until Alex pointed out that I had missed the last 5 medium levels, three weeks later still stuck on "Good Plumbing"!

GeoSwamp - Just in case you thought GeoDefense was too easy, the "creeps" no longer follow a set path but seek out the path of least resistance.

Crazy Machines - Logically figure out who to use the available tools and items to solve the set problem.

Ragdoll Blaster - Sounds ridiculous but there is something very theraputic about firing a ragdoll from a canon! Hours of challenge trying to get one of the dolls to touch the bull's eye. The solution is often not what you might first think.

StoneLoops of Jurassica - fire coloured stones to make groups of three or more, but be sure to catch all the bonus items and stop the stones reaching the end of the line.
