I'd hope if Simu was going to release another official FE, they'd get something for GNU/Linux which is a full blown OS with a 20+ year history.
That being said, I play via Tillmen's Profanity these days. He designed it partly (entirely?) for use on Android through a terminal emulator, and I suspect it would work just fine in iOS, too. I think the main way he's doing it is via SSH to a host machine, which may or may not be too tech savvy for you. I enjoy it as a minimalist FE which works very well under my laptop's OS.
