The most awesome retro SSH client

This app is probably the coolest app on my iPad and I have a ton of apps. The author needs to do a better job with keywords because I never came across it all these years of searching "ssh" or "telnet" or "retro computer" etc. This app uses modern graphics to give you that 1970s or 1980s CRT look. It is such an awesome experience. Just buy a $30 Raspberry Pi and ssh to it via your iPad and Bluetooth keyboard. I love the Cyan color and BigInJapan font. Makes me feel like a hacker in "Aliens." You can adjust the display glow for each screen character, zoom the font sizes, even introduce screen curvature, flicker, static, etc. if you like. No need to buy a real CRT monitor and hassle with it to get a retro feel. This app had better keep compatibility through iOS 10 and beyond! (Author, check your App Store keywords! You're losing out on purchases).

Almost there.

This is a great app, but as a user if the Mac version of Cathode, I find that it's missing some features. Mainly: bell sounds (seriously, not even a modern beep?), speed / baud rate control, and font size selection are the features I'd from the Mac version I'd like to see implemented here. In addition, I've noticed some problems when the screen is rotated; it doesn't seem to be allowing "full screen" programs to discover the terminal size has changed (I tested it with TinyFugue, and vim). One more thing: it's annoying to have tap twice to hide the keyboard.

Peace of mind and mobile productivity

The colorful interface is nice, but cathode truly shines in the peace of mind it gives you. Is there a system you babysit? Some tsk on a server you run sometimes? Cathode lets you do those things from anywhere with service. Suddenly, you can go to that music festival and not worry about something falling over in the middle.
