I released first lifestyle application the Playgrounds App which can search kids playgrounds.
The Content data is provided by http://spielplatz-radar.de/ that affords grounds from 46´000 in Germany, 2´800 in Austria, 1´900 Switzerland and 91´000 worldwide.
The development duration is less than one month and I've contacted a lot other providers who might provide localized data. The problem of the origin source http://spielplatz-radar.de/ is about accuracy location of grounds. I welcome localized organization who can provide exact data of playgrounds and I'll integrate data into the App as soon as possible. Download the application:
App is now opensource and can be cloned from GitHub.
