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

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? AI tools are the missing piece
