Personal finance web application Mint, last year’s TechCrunch40 winner, leaves beta today with a slew of new features under its belt, including investment tracking and flexible budget sheets, Jason Kincaid at TechCrunch reports. He writes that Mint registrations have gone up 100 percent over the last few weeks due to the financial crisis.

I was excited to read that Mint will have a new iPhone application by the end of the year; the ability to access financial and investment information on the go will really help take Mint to the next level. The ability to make transactions on Mint like on an online baking website, however, is still a long way off, according to Kincaid.

I republished my interview with CEO Aaron Patzer from the TechCrunch 50 conference last month. You can read my original post about the company here.
