Time Maths Shouldn't Be This Hard

I have two engineering degrees. I can do calculus. But ask me to add up 2:45 + 3:38 + 1:52 for a client invoice and my brain just stops working.

Last month I actually grabbed a piece of paper to calculate time for my timesheet. Made a mistake. Started over. Questioned my life choices.

Why isn't there a Time Calculator that just works? Right in the browser? Without opening some random website?

So we built one.

Why This One?
