Are there any third-party clients for Android that allow posting to both X and Mastodon?

I realize I may be out of luck here, because Twitter/X seems to have locked out third-party apps real good. Still, my line of work still has many folks on Twitter/X, which makes it difficult for me to fully switch over to Mastodon, and I would love a client that could ease the pains that this social media limbo currently imposes on me.
