 ## About
 
-This app is a project of my brother [Dominic Zedler](https://github.com/dominiczedler) and me, [Patrick Zedler](https://github.com/patzly). We started working on it during the first months of the Corona pandemic in Germany, just before our Abitur in 2020, when the schools had to close.

We started working on it during the first months of the Corona pandemic in Germany, just before our Abitur in 2020, when the schools had to close. Because Dominic switched to Apple devices in 2024 and doesn't actively use
+Grocy himself, he has withdrawn from the Grocy Android project, leaving me as the sole maintainer.
 
-We'd like to thank the developer of Grocy, [Bernd Bestel](https://berrnd.de/), without whose great work this app would never have been possible.
