alt Hacker Newswow... so much yak shaving, including priceless bits like "sat with ChatGPT for a bit [...] we came up with OurCar" (I mean... how original is that, clearly powerful datacenters computing over a dump of the Internet was needed), I'm impressed.
All this to avoid doing one subtraction (km before, km now) then multiplication (result times average litter/km) in your head.
That's a LOT of effort to be lazy.

The log for "who took the car for how long when and did they fill it up" seems to be much more relevant.
Nothing a notebook and a pencil can't fix, of course, but an app is more fun.
I don't think it's laziness, I think it's an excuse to do a personal hobby project. Makes perfect sense to me.
Haha, that's certainly one way to see it. I really enjoyed making the app, so it was less about laziness more about an itchy trigger finger.
FWIW if I were to do this I'd do
echo <input id=kmbefore><input id=kmafter onleave='alert( (kmafter.value - kmbefore.value) * priceperlitterperkm )'>
> index.html to make it available to anyone, Worldwide, for free!
For the fancy version I'd make priceperlitterperkm URL parameter to make it work not just for my area. But that's like an entire additional like of code.
My point being... I'd make a Web page, on app, no deployment, no tracking.
My ex isn't good with numbers but nevertheless she has a master in education. She has helped many, many children with learning deficiencies. For lots of people, the math is a significant barrier.
