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.

[Milestone 1]

[Move model + tests into shared package + start referencing shared code in existing app]

• Moving model code to shared package

  • Ongoing process but a lot has already been successfully ported

• Moving + modernizing model tests within shared package

  • Ongoing process but over 1.000 tests have already been successfully ported + modernized with Swift Testing (>90% test coverage)

• Reference shared model code in Skip app

• Reference shared model code in existing iOS app

[Milestone 1]

[Create shared core and ui packages + refactor existing code by using the repository pattern + move existing Swift UI code into package + move / create tests for shared packages]

• The initial approach in SkipSQL (to recreate a sort of “Core Data Light” in order to use the shared core (data model, services, etc.) directly within the existing app) worked for the most part, but it resulted in code that was difficult to maintain and poor performance when dealing with large amounts of data.

• Therefore, the decision was made to rethink the architecture and switch to a repository-based approach. Although this involves significant additional effort, it ultimately results in a much more decoupled architecture and thus a more maintainable foundation for the future.

• As part of this milestone, the first step will be to gradually transition the code that has already been migrated to Skip to the new approach, until all the features/views listed above are working again using the new repository-based architecture.

[Milestone 2]

[Finalize Migration of other views listed below + reference in packages]
