I built a focus app on a 6-inch phone in Ethiopia
I'm Geda, a 22-year-old self-taught developer from Ethiopia. I built NONOX — a focus app that forces you to focus.

Ask me anything! 🙌
The phone is part of the story but the real achievement is finishing something that people can actually use.
Appreciate that, Jim. 🙌
Finishing something people can actually use took longer than I expected — but seeing people engage with it makes it worth it.
Thanks for the encouragement.
The product is interesting, but what really stood out is that you built 8,500+ lines of Java on a phone. That's a level of persistence most people never experience. Wishing you a lot of success with NONOX—it's hard not to root for a story like this.
Thank you, Aryan! 🙏
This comment means more than you know. Building on a phone wasn't a choice — it was the only option I had. But I believed that if I kept going, something would change.
Comments like this remind me why I kept going. Thank you for taking the time to write this. It fuels the fire. 🔥

You're welcome.
One thing I'm curious about is whether your biggest advantage is actually the product—or the way you learned to build it under constraints.
Those often lead to very different companies over time.
That's a really thoughtful question, Aryan. 🙏
Honestly, I think the biggest advantage isn't the product itself—it's the process.
Building under extreme constraints forced me to think differently. No laptop meant I had to write cleaner, more efficient code. No team meant I had to design systems that were simple and self-contained. No safety net meant every feature had to be necessary and meaningful.
That mindset—building with limits—is what I carry into every new feature, every update to NONOX, and every product I build in the future.
The product can be copied. The approach can't.
What do you think? Have you seen similar patterns with other builders who started with constraints?

I have, but what's interesting is that not all constraints become lasting advantages.
Some shape a decision model worth protecting. Others quietly become assumptions that limit the company once the constraints disappear.
I have a few thoughts on how I'd tell the difference, but they're easier to explain than squeeze into a thread.
If you're interested, what's the best email to reach you on?
Thank you, Aryan. I appreciate this more than you know.

I'm genuinely curious about your thoughts on the difference between constraints that shape a company and those that quietly become limitations.
I'd also love to hear your perspective on where you see NONOX fitting into the bigger picture.
Looking forward to learning from your experience.
