Let me write your ASO App title and description. I am using the best tool to make research and I know several ASO (app store optimization) tricks for app ranking that I will also implement on your iOS or Android app.
- make your app more visible on german Google Play/App Store
- help you improve app rankings
- help your users to better understand your app's features
- possibly bring more traffic to your app on long-term
ASO Description is your only hope in fighting against the huge competition on both app stores. Also the use of keywords is very important. Trust me I have my own App and its always dificult to rank it, when you dont know the language. I am german so it is no problem for me to translate your texts and find the right keywords.
