Though these are silly (rich and nothing) in general sense, but how one explain thousands of match 3 games in play store. Come on, aren't they all same ? still many have thousands of downloads !!
In positive sense, they inspire me and tell me : "Do not worry what app you make. Even if many similar exists or the app does nothing beneficial to public, just add ads in it or make paid version, and upload it to app store."
You may be (pleasantly) surprised. Thanks to B4X, we can now do it very easily.
