$600/Month AI App Outearns Her Husband

💬 Hieu Dinh tweets…

My wife asked me to build her an expense tracker. I said no and introduced her Claude Code instead.

Now she’s building it solo and today her MRR just surpassed mine.

Hieu is an indie hacker in Singapore earning ~$570/month across his apps – including his own expense tracker.

His wife Mary Ha is a designer, not a developer. She had the idea for Finny – an AI-powered money tracker for iPhone.

Originally hired a dev to build v1.0, then discovered AI coding tools 🤖

Mary tweets…

I designed this app before I really understood how powerful AI was. That meant I had to team up with another iOS dev to ship it.

After experimenting with some vibe-coded apps, I’m now ready to solo the entire backlog.

That was January. By March, Finny hit close to 2,000 downloads at $1.99/month for the pro version 👀

And her MRR surpassed her indie hacker husband’s – the same husband who already had his own expense tracker.

Got an idea for a simple utility app but can’t code? No problem – AI tools are the missing piece 🔥
