I built a digital form filler for a poorly-designed that every Berliner must deal with. I explain what I did to make it clearer and easier to fill.
Unfortunately, from the bigger cities I checked (Frankfurt, Darmstadt, Kassel, Gießen, Marburg, Wiesbaden), none of them used that service, only some smaller districts like Bad Vilbel[1] or Limburg[2] offer the service.
