Instead of using and app for each service, you can use their page as webapp, with something like Native Alpha or web browser.

Fedilab supports multiple networks, don't take much to run it.

There are some pros and cons of using native apps or web apps.
Native apps can have some features that webapps don't, like direct/quick share, notifications....

Web apps you only need a web browser that's already included, don't take more space, use less battery for background process, and less permissions.
