Download the app for free from the App Store and choose an NGO to support. Right now we are helping Doctors of The World to communicate their important work.
When turned on Screen Donor then temporarily disables the screen saving mode on your smart phone. Instead of going dark the screen will display information from your NGO of choice. Like an inverted smart phone case. Thereby making your phone a small but important ad space when you leave it on the table in front of you in a meeting or at the coffee shop.
When turned on Screen Donor will consume battery time. A small price to pay for a good cause.
