Sad to hear, that no Android version is planned in the near future...!

Android is the global leader in marketshare of mobile OS so to have such an app for it would be of great benefit for John/ Pressgram and WordPress.

At the moment the app is like a colden cage in a colden cage (iOS)...

So we have to look for other alternatives, for example using one of the millions of Instagram bridge apps/ plugins to bring (mobile) fotos to our WordPress powered sites.
