Screen Donor is an app that turns your smart phone display into an ad space for nonprofits. The way that it works is that you download the app from the Apple store or Google Play, and then choose which nonprofit you wish to support from the list provided.
The app will temporarily disable the screen saving mode on your smartphone, where instead of it going dark, the screen will display an information screen about your chosen nonprofit.
The thinking behind this app is that it turns your mobile into an ad space for a nonprofit (which they don’t pay for), for when you leave it on the table in from of you in a meeting or at the coffee shop.
Screen Donor will consume battery time, but it’s a small price to pay for a good cause.
