How a Side Project Built Entirely on Mobile Got 167 Users in 30 Days (Without Spending a Dollar)
No time for side projects? This full-time employee built a SaaS entirely on mobile during nights and commutes. 167 users in 30 days. See his complete workflow.
Most indie hackers will tell you that you need a proper development setup to build a real product. A laptop, an IDE, maybe a second monitor. Time blocked off in your calendar. A dedicated workspace.
Abhilash KB threw all of that out the window.
Working a full-time corporate job, he built and launched a VCard QR code generator—entirely on his mobile phone. No laptop. No office. Just his phone, late nights in bed after his family went to sleep, and AI coding tools.
In 30 days, his side project has attracted 167 users, gets 3 daily active users consistently, and is pulling in organic traffic from ChatGPT, Bing, and DuckDuckGo.
Total cost? Less than $10 for the domain.
Here's how he did it—and why this matters for every time-strapped founder reading this.
The "I Have No Time" Problem Every Side Project Founder Faces
If you're building a side project while working full-time, you know the struggle. Your day job takes 8-10 hours. Commute eats another 2. Family time, meals, basic life maintenance—and suddenly it's 11 PM and you haven't written a single line of code.
The traditional advice is to "wake up early" or "optimize your calendar."
But Abhilash found a different solution: meet yourself where you already are.
Your phone is always with you. On the train. In bed. During lunch breaks. Waiting for a meeting to start.
What if that was enough?
The Mobile-First Development Stack (Yes, It's Real)
Here's Abhilash's complete tech stack:
Development:
ChatGPT with Codex plan (accessed via Brave browser in desktop mode)
GitHub mobile app for version control
Built the entire product using AI-assisted coding
Hosting:
GitHub Pages (completely free)
Custom domain (~$10/year)
Content Creation:
ChatGPT for content generation
Gemini for additional research
Perplexity for competitor analysis
Analytics:
Google Analytics mobile app
The entire workflow runs on his phone. When his laptop is closed for the night, his side project is still alive on his device.
The Keyword Strategy That Brought Organic Traffic
Getting traffic was remarkably straightforward. Abhilash used a simple but effective approach:
The most surprising part? ChatGPT is sending traffic.
As AI search becomes more prevalent, new domains with relevant, helpful content are getting discovered faster than ever before.
No aged domain required. No complicated SEO tactics. Just relevant content solving a specific problem.
Why Mobile Development Actually Makes Sense
Initially, building on mobile seems like a constraint. But it comes with unexpected advantages:
1. You Build in Small Chunks
Limited screen space forces you to focus on one thing at a time. No context-switching between 47 browser tabs. One function, one feature, one file at a time.
2. AI Tools Handle the Complexity
ChatGPT Codex doesn't care whether you're on a laptop or a phone. You describe what you need, it generates the code, you implement it. The AI handles the complex parts—you handle the direction.
3. Dead Time Becomes Productive Time
Can't sleep? Build. Waiting for someone? Build. Commuting? Build. The 15-minute gaps throughout your day add up faster than you think.
4. Lower Barrier to Starting
When you only need to pull out your phone, there's no "setting up your workspace" excuse. The friction to begin is near zero.
The $10 Validation Lesson
Here's the most important part of Abhilash's story: he validated demand before overbuilding.
The product is simple—it generates VCard QR codes. That's it. No fancy features. No complex dashboards. Just one thing done well.
And people are using it daily.
Now he's adding his first paid feature: the ability to add a custom logo to your QR code. Price point? Just $1.
Why so low? It's not about the revenue yet. It's about answering one question: "Will people pay for this?"
With 167 users in 30 days and consistent daily active users, even a 3-4% conversion rate means he'll see his first paying customers within 48 hours of launching the paid feature.
That's validation you can build on.
What This Means for You
If you've been telling yourself you need:
More time
A better laptop
A proper office setup
More technical skills
An aged domain
A complex tech stack
Abhilash's story proves you don't.
You need:
A problem worth solving
A phone (which you already have)
AI tools (which are mostly free or cheap)
Willingness to ship something imperfect
Consistency (even in 15-minute chunks)
The barriers to building in 2025 are lower than they've ever been. Mobile development isn't a compromise—it's a legitimate strategy for time-strapped founders.
The Real Secret: Community and Accountability
Here's the part that doesn't show up in analytics dashboards: Abhilash shared his progress in our Indie Masterminds community during our monthly Marketing Office Hours.
He came in just wanting to listen and learn. Instead, he shared his screen, showed his analytics, walked through his entire workflow, and got real-time feedback on his monetization strategy.
By the end of that 41-minute session, he had:
Clarity on which paid features to build first
A recommended payment integration (Razorpay)
A pricing strategy ($1 to start)
A public accountability goal: Launch monetization in 3 weeks
A check-in date at our next community call
That's the difference between building alone and building with others. Alone, you might keep tinkering. With accountability, you ship.

"Indie Masterminds is 100% worth the price. I was skeptical going in, because I don't know the people that are in the mastermind. So I didn't think I would get anything out of it. But because Ayush created this, I wanted to give it a shot and it is 100% worth it." — Bhanu, Founder of Feather
"The whole package is worth many folds its price. You'll get to learn from Ayush and other indies in your group. Getting the extra push and help needed to move forward in your project." — Khaled, Founder of Data To Page
"Just finished a great 4-week cycle of Indie Masterminds led by Ayush. Intensely insight-rich and actionable advice. Recommended to any indie founder looking for signal in the noise." — Andrew, Founder of Rollama
