Xappo is a one-man business, specialized in App Development for Android devices. I develop performant and secure Apps based on Your individual needs.


Please note that I am a one-man business so I cannot realize every app only by my own. But I have contacts to local partner companies which can develop large and sophisticated apps.

What does an app cost?

Often people are asking me that question. Please understand that I cannot name a rice based on a few information. This requires several steps. In a detailed discussion, requirements are collected and target groups are determined. This is followed by a feasibility analysis and an effort assessment. If it fits both sides, a service contract should then be concluded.

Plese contact me here.
