Show HN: I Got Tired of Calculator Sites, So I Built My Own

1 calculatehow 0 7/7/2025, 4:24:19 PM

I’ve always found that online calculators tend to have bad UIs, especially on mobile. Most of the calculator websites I’ve come across use outdated and inconvenient ways of inputting data, or they format the results in confusing ways.

I’ve noticed that fraction calculators (especially mixed fractions) are terrible to use, even on desktop. I haven’t built one of those yet, but it’s something I’m planning to tackle soon.

This is a project I’ve always wanted to work on, but I’m relatively new to this space. So far, I’ve created a collection of simple calculators focused on math and finance.

I’d really appreciate any feedback on the UI/UX or anything else you think could be improved.
