An iPad and this app are all I need

This app is amazing. It's simple, it's clean and it performs exactly as advertised. This app has been extremely good to me.

I use it to ssh into my schools Linux server to do all my programming homework.

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).

Made my iPad much more useful

As a command line (vim, zsh, etc.) user, Cathode lets me use my iPad to do real work.

I keep my computer running as a server and use Cathode to SSH into it. With some help from Dropbox, Cathode lets me use my iPad Pro 9.7" as my only computing device. I have so far written a bunch of code in Cathode with the Smart Keyboard, and haven't had too many problems. I like the retro look. I've toned it down a lot, leaving only some glow, burn-in, and scanlines, and it is very pretty.

I have a few minor annoyances.

1. Smart Keyboard support isn't perfect. For example, Cathode sometimes captures all the keyboard's inputs when I leave the app, leaving me unable to use the keyboard in other apps. I have to restart my iPad to fix this.

2. I wish the color options were more comprehensive. Ideally, I would want to be able to import an iTerm theme and use those colors.

I again stress that these are minor annoyances. This is an incredibly useful app.
