Refugees receive loads of mail from public authorities. How about a public authority mail translation app, where refugees upload mail from public authorities and volunteers check and translate it and thereby help the refugees?

In later stages, the app could maybe use OCR to detect: “This is a notification from the social assistance office, you have to be there at Monday, 7:00, and bring the following documents …”. Note: there must be an easy way to blacken personal data.

An online translator would also be nice. The refugee is in any public authority and needs somebody who translates German-Arabic. They start an app and it calls a translator who registered before in the cloud.
