After buying the software (60$ but worth it), you can sync transactions between PC, Dropbox, and iPhone. Excellent for budgeting and planning. A website and blog provide frequent advice and tips for money management. It can be set up to work with multiple currencies (I use Yen). Because I have the YNAB software and a shared Dropbox folder on my wifes PC too, she can record transactions that stay in sync with those entered by me from my iPhone/PC; this allows us to track our budgeting together more effectively and facilitates a brief 15-minute budget review that we do at the end of each month. If you are looking for a clear, effective way to manage your finances that is sophisticated yet very easy to understand and implement, then this software/iPhone app combo is right for you.
