Is this really how people do app discovery though? It seems like this is solving a pretty niche case, of "I know what I want, but I want a knock-off version of it"<p>One of my biggest challenges in the App Store (vs. the Play Market) is the ability to find an app based on what I need, compatible with the version of software I have on my device. For example: I defy you to try and find a stereo recorder app that is compatible with first-gen iPodTouch (abandoned to iOS v3.1.3). For that, there's no better option than a well-formed Google search.<p>Popping out the similar apps feels like it would be useful in a few categories (games, maybe one or two others), but isn't really going to help you find that new app you need, just help you in situations where you'd have multiple apps to fulfill the same need.
