I read the newspaper everyday but on smartphone there was no single place where i can read all my papers with good interface. So i built a webapp that got all of my newspapers in a clean interface and compressed way better, A business man liked the idea and we started building it as a proper app.
In 6 months we had a working Android app, Webapp, upload system for publishers, Solid backend and about 20 small publishers. I was than working on prototype that will add a play button to every major story that will play the news story video in the newspaper interface (inspired by harry potter, looked like that too).
We cound't get the biggest publishers in time, have to close it down withing a year but learned a lot in the process.
