    How does it compare to the (extremely expensive) Prompt 3 app? I'm still stuck with Prompt 2 which I now don't even see on the App store anymore. Been waiting for a decent non-subscription based alternative

    I generally use iSH[1] for my iPhone to Linux needs. Specifically, I like it because it's a standard Linux distribution with OpenSSH. Meaning all the things work like sftp, ssh, tunnels, and local clients like `mysql` tunneled through ssh

      I use iSH too and love that I have all my standard CLI tools available, or can just install ones I want.

      But using the ssh client in iSH to interact with TUI interfaces is a less than optimal experience. Many nice UI affordances that something like Terminus provides are lacking. Like using swipes as input, key management tools, or using location monitoring as a trick to keep it running in the background. Definitely excited to check out this new Echo client.

      I also love iSH. However, I haven't been able to run agents directly from my phone on it like I would hope.

      I spent a few hours trying to get GitHub Copilot CLI or Claude Code installed only to discover that the version of Node is pegged to 14, which prohibits installation of several of these tools via NPM.

      Has anyone had success with this? I'd love to see the packages updated to support later versions

    I'd love the ability to run a command on connection to a server (like "tmux attach -t main") and also a way to create my own buttons in the UI to send things like tmux commands (next window, create window, etc) to make it easier use from my phone.

    Also, and I'll probably just buy it to test, but how does it handle copy/paste and STT? Especially with coding agents I use speech-to-text to explain something and that's always hit or miss in terminal apps on iOS in my experience.

      It looks like you set a startup command in the "Advanced Configuration" menu for the host

        Nice, thanks for letting me know!

  • JLO64 2 hours ago

    This is pretty awesome, and at a $3 price point is an auto purchase for me!

    As someone else said though, hardware keyboard support on iOS is something that I would really want as I regularly use ShellFish on my iPhone with a USB-C keyboard.

    Something that actually matters more to me is font support. I use nerd fonts for my zsh prompt, so an app that doesn't support them is a hard sell. Are custom fonts supported, or at least on the roadmap?

    Additionally I just want clarification on your business model. Once I pay now I will get all future updates for free or might I have to pay for them?

    EDIT: (Since Ghostty supports it) Does this also support showing images in the terminal via the kitty protocol?

    Very cool! I've been using Termius for a while. Overall positive, but my one complaint is that the interactions can be pretty tedious using it with TUIs like Claude Code. I like the gesture-based movement, excited to try that in practice.

    I use Tailscale SSH, so one very small bit of feedback is that it took me a second to realize I just needed to put a dummy password in to actually get to the connection.

    Neat, it's staggering that there hasn't been a good non-subscription option for a simple utility like this for iOS. I've used Termius for a while, but it pushes a subscription and AI features pretty hard.

    I think this really needs the ability to generate SSH keys on the secure enclave, like Secretive[1] does on macOS.

      There used to be a couple non-subscription ones. I’m still using Prompt 2, but of course it’s been superseded by the subscription-bound Prompt 3 on the App Store for some time now.

    • sgottit 44 minutes ago

      Thanks! Agree - Secure Enclave support with key generation has been a common feature request. Definitely on the roadmap.

  • hk1337 11 minutes ago

    It looks really nice and clean. It's an SSH app though, right, so I would need a server to remote into?

    • lambdas a few seconds ago

      Something running an SSH server service, yes.

      A decade plus ago, you could ssh into localhost on iOS, but that got nipped in the bud with sandboxing.

  • jlundberg 2 hours ago

    Interesting project!

    Two problems for me:

    - I want my iPhone terminal to be built for use w/ external keyboard.

    - While I really like pay-once a use-often app like a terminal you really want to try before you buy. But maybe Apples general refund-if-not-satisfied is still a thing and enough?

    • sgottit 2 hours ago

      Echo works great with an external keyboard fwiw. My daily driver is using it with the iPad and keyboard

  • setopt 2 hours ago

    Purchased. Love the app.

    A few requests:

    - In Secure Shellfish, I love that if iOS suspends it and I reopen it, it just does `tmux attach` on the last host automatically. Echo has the "startup command", but seems I still have to manually click on the last host I used to resume. Perhaps we can get an option to auto-reconnect to the last host? (My work firewall blocks Mosh so I need to do the ssh-and-attach dance when iOS kills the app.)

    - When using Emacs on iOS, it would be great to be able to save keychords like `C-x C-s` or `M-x` somewhere, for example on the virtual keyboard top row. (I would be ecstatic if I could use the volume buttons as Ctrl and Meta, but I guess that’s more complicated to do.)

    • sgottit 2 hours ago

      thanks that's great feedback. currently thinking and working right now on the best way to handle customisability of the keyboard (without making it a chore to configure or a horrendous ui). hadn't considered "chords" yet but it's one we'll consider as we approach this

  • kastden 2 hours ago

    In the App Store it says it requires iOS 26.2 or later. Any reason it couldn't be made to run on iOS 18? I only ask because I don't wanna upgrade to Liquid Glass!

  • laksjhdlka 2 hours ago

    How do I add other keys to the little virtual keyboard? Inability to easily type ` is pretty tough. Looks beautiful though.

    • sgottit 2 hours ago

      Thanks! We're working on an update to the keyboard toolbar right now to support a customisable set of keys

      • kristofferR 22 minutes ago

        Combos too please, like shift-tab for Claude Code.

  • cadamsdotcom an hour ago

    Very nice! But, looking at the keyboard, there is a bunch of wasted space above the top row of keys that I just don’t understand how Apple put there. When you’re working with tiny text in a terminal every little bit of space matters and on tiny phone screens it’s crazy they would do something so strange. Does anyone know if it’s possible to remove that top bit of wasted space from the keyboard on iOS 26?

  • xqb64 an hour ago

    Does this work with a Yubikey?

  • jasonjmcghee an hour ago

    Nice job! Purchased. Would love to be able to make the font much smaller. It says "10pt font" but it is still larger than I need and would love the extra real estate.

    • sgottit an hour ago

      You can pinch to zoom in and out beyond the defaults and get a lot of real estate that way. Thanks for the kind words!

      • jasonjmcghee 38 minutes ago

        thanks - follow up, it logs out every time my phone screen locks - is there any way to make it not log out?

  • dpoloncsak 2 hours ago

    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.

    • sgottit 2 hours ago

      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.

  • sprak an hour ago

    Looks nice. Does anyone know if there is something similar for Android?

    • tills13 an hour ago

      Termux is the OG.

  • gu009 an hour ago

    Would be great to see some more ssh key features from Termius implemented: generating new keys, including keys that are stored in the Secure Enclave, exporting keys to hosts directly via the app

  • torstenvl 2 hours ago

    The requirements for this seem strange. What is it about iOS 26.2 that makes it a minimum requirement?

  • whalesalad 27 minutes ago

    Some brutal reviews on the iOS app store suggesting RSA keys do not work?

  • ktm5j 2 hours ago

    Any chance you'd consider an android port?

    Amazing! Insta-buy for me.

  • stuxf 2 hours ago

    finally I can move off termius, this looks great!

  • iririririr 2 hours ago

    Nice. Hopefully it will evolve into something as good as termux on android. It won't ever be as good, because ios is a toy with rubber on all corners.

    Love that they copied the bar above the keyboard. Even with android custom keyboard that was a great feature, on IOS that's essential.

    oh, it's closed source. and lazygit (the least terminal based of all cli tools) being their inapiration doesn't inspire much confidence in long term :(

    • cyberpunk an hour ago

      I’ve been using blink on ios for years it’s opensource and works pretty well for me.

      I actually kinda like working on my ipad this way (ssh’d into dev box) it’s not really distracting somehow and not having full jetbrains etc makes for a different kinda session.

      shrug

  • lilyball 19 minutes ago

    This sounds nice, but since you're talking about using it with agents, to what extent was AI used to actually write the app?
