No. But you can use it to find interesting apps, and then use either F-Droid/Droid-ify to search the app name and install it, or by copying the URL for the GitHub/Gitlab repo linked on OpenAPK for an app into Obtainium. That way you’ll get updates.

It uses FDroid and GitHub as sources

Nice for discovery, but I’d still recommend actually installing the apps using either F-Droid/Droid-ify, or by adding the GitHub/Gitlab repo linked on OpenAPK for an app to Obtainium. That way you’ll get updates.
