Thanks! Yes, that's a bit annoying to change it again and communicate (and, possibly, confuse users even more). Agree, the search engines suggest Termius as a fix now, so we'll probably leave it as is.
But, perhaps you could do something with the capitalization of the name to make it more obvious:
"termiUS"
You could accentuate that effect with using a larger font for the last two letters.
Seems like one of the benefits is synchronization, so emphasizing US fits. And then you don't lose your hard fought Google ranking.
But, in any case, it's a great product and good luck!
