The ultimate family efficiency tool. The OurGroceries app synchronises your regular shopping lists amongst everyone's devices, so if you've run out of eggs, add it to the list and hopefully your significant other will pick them up on his way back from work (and they don't even need a Blackberry to do this). The speed at which you can add and drop things from the list is impressive, as are the supplementary features such as recipe creation and Internet backup of all your lists.

There are plenty out there and My Mileage Tracker certainly isn't the cheapest, but it goes above and beyond the call of duty with great configuration options and desktop synching. Although it has a wealth of tools and setting to play with, at the same time it is fast and efficient to interact with. The desktop application is a very useful addition to the bundle.

The near-universal praise from people who have downloaded the Mobile Checkbook app is not only astounding but entirely justified. You can now throw your physical cheque book out of the window (figuratively, at least) as this app makes keeping track of withdrawals, deposits and payments an almost instantaneous process. In addition to the unbelievably speedy design, it can theoretically support infinite accounts.

If you have a lot of accounts, passwords and PINs, you not only want something that can remember them all for you but also something which is ultra secure. Ascendo DataVault ticks all the boxes and is immensely easy to set up and gives you instant access to all you card numbers and everything else you could possibly need. Great features include desktop synchronicity and the option to import data from browsers and other online wallet-style tools, and the backup function is handy to have for peace of mind. A truly brilliant data protection and timesaving tool which more than justifies its heft price tag.

There are a number of expense trackers out there which do the job well, with apps such as the simply titled Expense Recorder performing the basic functions amicably. However, if you're a business professional or contractor looking for an expenses program with a bit more depth, you'll want to download the Exgis app before you next head out the door. A great set of features and customisation coupled with superb functionality make this a winner.

The ALC Pro is a very neat app for working out repayments on a car loan and, ultimately, whether you can afford it.

In short, it has a brilliant interface, is fast and comes packed with features.

While no decision as big as refinancing a mortgage should be taken lightly, this app can simulate various hypothetical situations to see what works out best. The interface is nice to work with and it can deal with a range of scenarios - perfect for figuring out your individual needs (and developer Davide Perini has a range of other mortgage related calculators).
