Android App

[05.08.2023]

This feature would be very cool, but also very large. At this point, it would probably take another 1-2 years after the feature development has been started. So this is just a placeholder for now.

However, I would love to hear your ideas! :)

[19.12.2025]

Since a complete rewrite of the app would be extremely time-consuming, the best option seems to be using Skip instead of building everything from scratch using Flutter, React (Native) or Kotlin. That doesn't mean there will never be a web version, but the focus is on Android first and then, possibly later, on a web app that is truly optimized for the web.

Additionally, modernizing the app with Skip / SwiftUI would benefit existing users as well by delivering new features more quickly in the future and improving app stability overall.
