Built BoomerBill in a Day — A Tiny App to Track Unpaid Tech Support Time
Hey IH
I built a small app this week called BoomerBill.
It tracks how much time you spend on “just one quick thing” tech support and converts it into lost freelance income based on your hourly rate.
What started as a joke turned into something surprisingly revealing.
If you’re a developer or freelancer, you probably get this:
Individually, they feel small.
Collectively, they add up.
But because it’s informal, we don’t track it. And if you don’t track it, it feels like it doesn’t exist.
I wanted to measure it.
BoomerBill is intentionally simple:
It converts minutes into lost income using your hourly rate.
No billing. No invoices. Just awareness.
No SSR.
No backend.
No analytics.
No SaaS.
Just a small, honest tool.
The trickiest part was keeping the timer visually ticking every second without mutating store state continuously.
The timer UI updates locally.
The session only commits to the store on Stop.
This kept state clean and testable.
Two reasons:
After tracking for a week, the numbers were… higher than I expected.

Would love feedback on both the idea and the implementation.
