Ask HN: Please review my startup, CashBase (personal finances)

http://www.cashbasehq.com

CashBase is a personal finance app for people who hate personal finance apps.

It's a side-project, started as a web application, but since December we have an iPhone app and the Android app is on it's way, ETA 1 month.

We launched it (almost completely) silently in June 2010 and now have over 2,000 users. The app is completely free (web + iPhone) because we have yet to find a good business model. But we're using this time to improve the product, connect with our users and figure out how to make money.

What features do you consider would be worth having in a Premium paid subscription and for how much (per month)?

We'd love to find out what you think about CashBase!

Thanks :).
