Hey! I'm a co-founder of Kickfolio, one of Melbourne's own AngelCube startups. A friend just messaged to tell me you said you 'really need to make a promo page for your apps'. Thought it might be cool to point you to http://kickfolio.com. We're in open beta - please let us know what you think, if it does help you!
Congrats on the success of your apps on the app store and good luck with your upcoming venture.
