Can you do real development from your phone — one-handed, on the subway?
I'm a senior developer in Seoul. My commute is long and the subway is always packed. Here's how I tried to make mobile development work — and where it fell apart.
Seoul subway is not quiet. You're standing, one hand gripping a bag, the other holding your phone. Coding the traditional way — IDE, terminal, file trees — is physically impossible. The screen is too small, your fingers too fat, and the text too tiny to read without squinting.

The problem in a nutshell:
- One hand is always occupied — VSCode isn't built for that
- GitLab on mobile: tiny font, dense UI, constant zooming
- Managing issues, CI pipelines, and logs across tiny tabs is exhausting

What I tried
In the age of AI agents, I realized: I don't need to write the code myself. I just need to manage it.
So I built a small site, connected it to GitLab, and set up this workflow:
1. Create a GitLab issue from my phone describing what I want built
2. CI/CD scheduler triggers — a runner picks it up automatically
3. AI agent resolves the issue — commits, tests, deploys
4. I review the result — from my phone, while still on the train
It worked. But then GitLab on mobile killed the experience. Too much visual noise. Too ma

Quick note — the post got cut off mid-sentence (it ends at "Too ma..."). The full version was supposed to end with: too many tabs, too much context switching. That's exactly what pushed me to build something.
Anyway — the solution I built from this frustration is launching tonight on Product Hunt: Spring IVE, a minimal mobile dashboard for AI agent workflows. Designed for one thumb, on a moving train.
Would love your thoughts when it's live! 🚇
This is exactly why I stopped trying to code on my phone and just use mobile for monitoring deployments and reviewing PRs instead.

“For these reasons, I thought about it a lot, and that’s why I created Spring IVE.
Give it a try — it’s free^^
Let me know if anything feels inconvenient. I’ll fix it right away.
I’m currently using it for my own project and finding it really useful, and I’d love to share that experience with others.“
Hey, also based in seoul here.
Most of the times on the subway I just use claude code cloud to review PRs and set up menials tasks, or to brainstorm for more ideas. I probably spend more time pushing a task then not looking at the screen but thinking more.
Tbh i'm a little conflicted on what the mobile experience should be in the first place. In the end there's a fine line between loving/having to do your work and letting your brain rest at appropriate spots.
I love spending time on my projects, so i do work on mobile quite often, but it often came at the cost of just absolutely crashing at home from trying to focus while the bus/subway was constantly shaking back and forth.
And if we're not on the move then I can just pull out my laptop.
Navigating the "one-handed struggle" on the Seoul subway is the ultimate developer endurance test! You’ve brilliantly shifted from code-writer to orchestrator, which is exactly where the industry is heading. It’s wild that AI can solve logic in seconds while legacy mobile UIs still force us to squint and zoom. You’re building a "Manager's UX" for a world that hasn't realized the IDE is moving to the background.
