Because of my work as a geoinformatics specialist and my likely innate interest in technology, I also apply the knowledge I’ve gained in this field to app development.

Here you’ll find mobile apps I’ve developed, available for free download and use. These apps are free of ads or any “data collection features” and have been programmed to the best of my knowledge and belief.

“Ask Opa” is a mobile app that features a special chatbot named “Opa.”

He is programmed to be a friendly, empathetic, somewhat philosophical, and positive character—one who is also capable of learning. He has interests such as nature, the mountains, his garden, social engagement, helping others, music, art, handpans, jazz, good food, sustainability, cooking...and every now and then, he also enjoys a cookie.
Users of this app can chat with Grandpa in various languages and can change the language at any time and as often as they like.

Conversations with Grandpa are saved as memories—and can be resumed at any time. Of course, these can also be exported, copied, or deleted.
Any users who have suggestions regarding the further development of Grandpa’s character (what should Grandpa pay more attention to, what doesn’t Grandpa do so well, etc.) are cordially invited to send them to mazop@gmx.at.

“Ask Opa” is currently still a so-called release candidate—that is, a version that has not yet been officially released or made available in app stores. The goal is to thoroughly test the Opa character in order to improve it further. But from a technical standpoint, this version of the app works flawlessly, at least on Android.

An App Version for Apple/iPhone will be available soon.
Currently, there is only an Android version.
