I have also seen a lot of people saying "well the app is called Mastodon" — sure, but there are a lot of other apps you can use. Tusky, Metatext, Fedilab and literally dozens more:

If you happened to download "Fedilab" first, would you argue the whole network is called "Fedilab"?..
And being aware that there's a broad spectrum of options might help you find a mobile app that maybe even works better than the official one. :blobcat_owo:
