Keeping apps up to date is a powerful feature of app stores. Interestingly, some Android FOSS apps have found a neat way to handle this with built-in 'auto-update' and 'check for update' options.
This method allows apps to operate independently from the app store while still staying current, enabling one-click updates and installations without needing an app store or Obtainium.
The next version of AppCore will include this feature, and I really like this approach, it addresses a key challenge for open-source apps.
