In the modern world, we all seem to be constantly working in various different currencies, whether that be the U.S. Dollar, British Pound or the Euro, not to mention the countless other currencies that make the world go round. Converting currencies is the kind of thing that has been made nice and easy thanks to the App Store and the plethora of apps that allow the conversion of a wide range of things, often not just currencies.

Third-party keyboards that exist on the App Store - such as the increasingly popular Swype - have promised to make typing out lengthy strings of texts on iPhone and iPad a lot easier and faster, but so far, haven't managed to really achieve that increase in productivity that users would like. There's no doubt that with a bit of improvement and learning from user feedback, existing third-party options will get better with time, but if you aren't prepared to wait then there's always the option of downloading Nintype, the new kid on the third-party keyboard block, promising typing speeds of up to 130 words-per-minute.

If you're a little on the geeky side then you probably love a good statistic, we know we do. It also means that we like to know every little detail about the hardware and software we use. Apps like iStat Menu are always popular amongst people that like to take a keen interest in what's going on with their systems, so when we hear of a new app that does a similar thing for iOS but is free, we take notice.
