Ask HN: How do I sell my iOS app?
Is there a Flippa for mobile apps?
We actually partner with AppBusinessBrokers - good guys. They handle the $200,000+ spectrum while we really specialize in the $1,000-$150,000 range. SellMyApplication is unfortunately more of a marketing site and lack the real data/stats and the ability to help with the actual transfer.
We are happy to help however we can, and actually thought you might find this informational post about iOS transfers specifically really valuable: http://blog.apptopia.com/iosappstransfer/
Chad Mureta, author of App Empire, recommends these guys.
