Children's Hospital app [not relevant]
There is now a huge fundraising campaign in Finland for the new children's hospital and many companies are sponsoring the project. As Jolla probably can't take part as a donor, there could be an app for the users to take part in. The app could follow the amount of fund raised in the project and include a button to donate (SMS, call or credit card).
The app should probably be made together with the foundation. This way Jolla could be listed as one of the sponsors and the company takes a strong role as a social benefactor following in the footsteps of Supercell!
