(slightly OT) I don't understand Flippa; I've search several times for a regular web site making a bit of money and all of them look like scams, even the ones that are sold, with no PageRank since all the incoming links are spam.
Any decent marketplace for one-app or brand companies needs to prominently display intedependently-verifiable, evidence-based due-diligence metrics than can be dug into by your legal and forensic/tax accountant folks before a transaction. Saves lots of time. BTW: on apps, it is usually more profitable to license source code to games and similarly common apps (say for gyms, restaurants, etc.). If it's a FNAC app that you're bored of try to sell it, first, don't just throw out your work (or at least salvage the best parts business of assets/staff/knowlege)! Reduce, reuse, recycle.
(Some, but not all, due-diligence is worry alleviation through hazing ritual business theatre.).
