Prospects is the best financial application out right now for Mac. Like many others, I must have downloaded the the trial versions of every Mac financial app out there including Cha-Ching, iBank, Moneywell, Squirrel, Money, Moneydance and even the beta for Quicken Financial Life. None of these quite did it for me, and could not combine at-your-finger-tip information, and ease of use in the same way Prospects does.
Budgeting features tend to turn me off many of the apps, where either they weren't intuitive or not attractive in their presentation. Prospects budget manager was nice in that it can be toggled on or off, and even swapped out with more detailed segmented information like individual spending per category, balance tracking, and monthly summaries.
The charts tend to be robust with drop down submenus, and multiple methods of sorting through data. This makes it easy to track and compare spending and saving habits in side by side segments.
The Prospects home page is a series of easy to read charts tracking total assets versus liabilities, and a month by month breakdown of how your total net worth has changed over time. All of these graphs are quite visual and can be viewed at any time without the need to run them as reports.
Importing OFX, QFX, and QIF from my banks has gone smoothly, although there currently is no automated "connect to bank" feature in the program. I've had no problems with any of the calculations, and all of the features that are in, seem to work.
Currently, there is no support for investment data, no direct-connect, and no bill pay so be careful if those are "deal breaker" features for you in a financial application. I've found that what Prospects does do, it does very well however. I look forward to many solid releases to come.
