In a continuing effort not to "reinvent the wheel" but to address the continual interest in productivity related iPhone apps, I wanted to point you today to a great post over at The Simple Dollar that features Ten iPhone and iPod Touch Apps for Personal Finance Success.
I'll second Trent's recommendation of mobile banking applications. I've been very pleased with my recent installation of the Bank of America app for quick check ins on my accounts. I also love "Check Please" for mindless tipping assistance when I don't feel like doing math and "My Budget" for planning purposes.
I love that Trent has included an overview of some of the great apps from Google, which continue to make my life more productive and happier on a daily basis!
What are some of your favorite tools for mobile finance?
