I lived in Berlin many years where with time I had a group of friends to spend the dark cold nights of winter and (sometimes) summer. My social circle grew up slowly, still at times I had no companion to many of the activities the city has to offer. Not only once, but many times my friends were not interested or had not always free time to join me.
The "Share culture" App is the result of those days. It is a place where you can find activities that interest you and let others know about it, allowing you to meet fellow enthusiasts like you.
