Do you offer an NDA?
Sure. If you want to sign an NDA before we start talking about your project, we’ll send you an online document. Let us know if you need it in an e-mail, and we’ll prepare an NDA immediately.
Do you have experience with e-commerce apps?
Have you ever worked with Scandinavian companies?
Our mobile app development company has created several apps for Scandinavian clients, such as Egmont (Bamse) or Universal Music Group (Kiidio). They were released on Danish, Norwegian, Swedish, and Finnish markets. We continuously observe local trends and keep ourselves up to date with Scandinavian mobile app landscape.
How do you work with international teams?
Online meetings and workshops are our standard way of operating. Sweden and Poland are in the same time zone, so scheduling becomes easier. We also use tested management solutions and communication platforms to pass the information quickly and avoid delays. You need to see us in person? If traveling by plane, Stockholm is just 2 hours away from Wrocław.
What billing methods do you offer?
We prefer the time & material billing model. It gives both us and our clients more flexibility. An alternative is a fixed price method. It’s a good option when you want to build a small, simple app with only a few basic features.
