Why I built this

I'm a general dentist. When I need to write a liquid antibiotic script — which isn't every day — I found myself looking up the same things every time: concentrations, weight conversions, max doses.

It's the kind of task that's just infrequent enough that the details never stuck, but important enough that I didn't want to get it wrong.

So I built a tool that remembers for me. Now when it comes up, I get the right answer in seconds instead of digging through references.
