Mint.com and Personal Assistant.com are two financial apps that help track spendings.

When it comes to personal finances, for a lot of people, the common complaint used to be that they lacked the tools or the time to do a good job at monitoring all their different accounts or every single one of their spending. Those days seem over with the development of personal financial sites with most of them offering free basic products on their Web sites and now almost the same products in the form of apps for mobile phones.
The pool of such tools to choose from, is deap and ever expanding. The new York Times just reviewed a few of them and found that Mint.com owned by Intuit and Personal Assistant.com from parent company Pageonce.com, stand out of the crowd.
Mint.com is available free on iPhone and soon on Androit while Pageonce Personsal Assistan.com offers free ads supported versions on more platforms like iPhone, Blackberry, Windows Mobile and Android and ads free versions for $7.
To use either service, you will have to give them your login and passwords information for all your financial accounts that you want them to track like credit cards, mortgage, utilities etc. And among other things, they will send you a S.M.S. or e-mail alert when a bill is due or when your balance on your credit card hit a certain level for instance. Both services work almost the same way by offering you a summary of as many accounts or activities that you want to track, and they refer you to some financial products that may be worthwhile for you.
The way they are able to do all that is by linking to thousand of financial institutions.
Beside Mint.com and Personal Assistant.com, there are two other services worth taking a look; BillTracker.com and BillMinder.com.
According to the New York Times, the main atttraction of those two services is the fact that they are minimalistic in the sense that only the user can actually see what information is contained in their accounts. But on the other hand, they require more work since the users have to manually enter all the data to the different accounts that they want to track.
