App development in Mölln: frequently asked questions
What others wanted to know before the first call.
What does App development in Mölln cost?
That depends on the scope, not on the location, so we do not quote flat rates in advance. After the first call you get a written offer with scope and schedule before anything starts.
Do you come to Mölln?
We are based in Greiz in Thuringia and work for clients across Germany, Austria and Switzerland. Workshops and shoot days take place at your site; in between we coordinate by video.
iOS, Android or both?
Usually both from one codebase. Where something has to be really native, we build it natively — that is decided in the concept, not afterwards.
Do you look after things after launch?
Yes. Maintenance, further development and channel care are available as ongoing work.
