iOS: A terminal emulator on your iPhone might sound a little silly for most of us, but SSH can come in pretty handy sometimes. For a while, one the best apps for doing so was Panic’s Prompt 2, but Blink Shell is an option that’s worth a look too.
At a glance, Blink Shell is similar to any other terminal emulator, but since it supports Mosh as well as SSH, connections tend to be more reliable. Blink Shell supports external keyboards, which is handy if you're using it on an iPad. As you'd expect, there's a handful of customisation options to change the font and colour scheme too.
That said, there is a learning curve here because Blink Shell lacks traditional iOS menus, which takes some getting used to. You'll need to type out "help" to pull up information or "config" to get to the settings. Everything else is done with swipe gestures, which you can reference back to with the "help" command. Blink Shell is pricey at $30.99, but it's also open source, which means you can build and contribute to it yourself if you're interested. It's also a pretty niche app, as most of us don't need to do remote SSH particularly often. If you do though, Blink Shell's well worth a look.
