AppMakr.com is a platform that helps anyone build apps and we launched over-the-air one-click install for testing back in November for our users; we call it AppDrop. You can find more info and watch a video here: http://go.appmakr.com/appdrop.

AppDrop and similar techniques really helps in reducing the friction of getting an app tested and made. This is a trend that more and more solution providers will jump on.
