I think I might be able to make this app work in a future version of Hydra. It uses Nokia platform services, which are currently not enabled, but I've done some initial work on them already long long time ago. Problem is mostly that Nokia's documentation of the API is broken (a lot of 404 errors online) so it's kind of detective work trying to reverse engineer how the API is supposed to work.

Also, as I mentioned earlier, the app relies on some native components (namely, the "API Bridge"). But it only uses it for uploading the images, so I think there might be a way to overcome this.
