I am working in a library. Regularly in library happening events, like concert, exibition and so on. So the startup idea is - to create app for android, so that each visitor of the library could easily get notification about new event in library.
All people in the city can install this app into their phone, and get notification about upcoming concert or other event.
This app can exist for any company, and people who like this company can install this app and get notification about new event.
In the screenshot shown, that "new concert is upcoming in the library"
