Kvarterskollen was developed during East Sweden Hack 2014. The target user is citizens of Linköping. The user writes a street in Linköping and Kvarterskollen shows which group (e.g. students, party-peeps, elders) is most likely to enjoy living in the nearby area. The matching algorithm between groups and areas is based on how far it's to points of interest (e.g. University, bus stops, shops).
The hackaton was during 20 hours and it was me and another friend that created the application from scratch.
