I'll spend the $3 to try it out.
Any real different than Terminus? That seemed to be the latest and greatest last I was shopping for an iOS SSH client.
Also, maybe just because its new (I dont realy know how App Store search works) but searching "Echo" and "Echo SSH" returned way too many Amazon/Alexa related apps, and then many other terminals before yours.
Terminus was a sledgehammer for the small, neat little app I wanted to build (though I'm sure it's great). Plus a big driver was the ability to use Ghostty's engine. I'm not familiar with what Terminus use under the hood.
