"The app offers a controlled and safe environment for schools to foster team spirit off the field by providing online notice boards, social feeds and other 'always on' channels through which players and coaches can communicate."
The platform would offer live and on-demand coverage of games, live scoring, and a coach and media channel.
Supporters wanting to view secondary sports games online can pay for a 'ticket' which gives them access to a live stream of their chosen match, as well as on-demand access for the next seven days.
Twenty percent of every ticket purchased is donated back to the schools to reinvest in sport.
The app has drawn the support of Spark, and Spark's Head of New Things Philip Ivanier said there were two reason behind their interest in the project.
"Every All Black or Black Fern has to start somewhere, and like all Kiwis, grassroots sport is close to our hearts. We love the way SidelineApp opens up the potential for a much bigger audience watching school and junior sports games anytime and anywhere," Ivanier said.
"But it's also bigger than that, because SidelineApp has created a content platform that can be used for a range of other grassroots community-based events. As an entertainment proposition it is truly impressive."
