Assuming for one minute I actually had any money to track, PocketMoney from Catamount software which has shown up on Installer seems to be a more feature complete financial manager despite being in beta compared to the only other previously available financial manager for the iPhone, Mobile Money. It has a thorough menu for keeping track of different transactions and the categories they belong in. Hopefully syncing with online bank accounts and transactions will be implemented in the near future.

From The Developers Site:

PocketMoney® 1.0b1 for iPhone

PocketMoney has been an award winning and popular personal financial manager for the Newton OS since 1994 and for the Palm OS since 1999.

PocketMoney was designed to do one thing and do it very well – track your finances quickly with the smallest amount of work. PocketMoney will help you keep your checking, savings, credit card and petty cash accounts in line.

On the Newton and Palm OS, PocketMoney interfaces with a variety of programs to give you seamless integration of your financial data with their specialized features. Some programs PocketMoney works with are tip calculators, vehicle logs, budget managers, and customized data entry applications. After we get version 1.0 released then we’ll start working on this interoperability and be bringing classics like CheckPlease and MPG to the iPhone.

PocketMoney keeps the amount of data entry to a minimum and at the same time gives you a great amount of flexibility. Unlimited accounts, categories, subcategories let you track data your way.

What’s that you say? The iPhone doesn’t have a native currency converter but only web apps available to handle it? Well, in actuality you do have a built in currency converter in the form of the stock application for the iPhone along with the built in calculator. In order to get the current currency exchange rate, you need to input the desired currencies into the appropriate formats specified by Yahoo as that’s where the info is being delivered from. So for instance, following this formula “USDPHP=X” where USD being the American Dollar and the PHP being the Philippine Peso, would give me the current exchange rate of the American Dollar into the Philippine Peso.
