Building TokenBar taught me that shipping fast is not the same as shipping smart

A few weeks ago I got surprised by an AI bill and built TokenBar because I wanted a dead-simple way to see token usage live from my Mac menu bar. That part made for a clean founder story. The messier part is what happened after. I shipped the first version fast. Then I did what a lot of solo devs do when they feel momentum: I kept polishing the thing that already existed instead of facing the harder problem. I tweaked the UI. I added little quality-of-life improvements. I thought about more features. I kept telling myself I was "shipping fast." But shipping fast is not the same as shipping smart. The expensive mistake I made building TokenBar was not the original bill. It was spending too much time improving a product before I had real proof that strangers cared. That's the trap with small Mac apps. They are fun to build. They're tight in scope. You can make visible progress in a weekend. And because the app actually works, it's easy to confuse product progress with business progress.
