>> "Download & get your termin today!"

That sounds rather... denglish. Is 'termin' really synonymous to appointment in english? Never heard that term before. On the other hand, cool interface for the app. But its a shame that you need an app for something basic like getting an appointment with you local Administrative Office.

Yes, that's how appointment is called in German. I must admit it sounds a little weird, but hopefully would work for SEO.

By the way, the app is done with TypeScript and React Native/Redux.
