Show HN: I'm building a site to host 1k free, ad-lite calculators

https://straightcalculator.com/
1•priteshgkoshiya•1h ago
Hi HN,

I'm a full-stack developer who got tired of searching for simple calculators online and landing on pages that are 90% ads and SEO fluff, with the actual tool buried at the bottom.

I decided to build StraightCalculator.com. The goal is simple: straight-to-the-point tools with zero clutter.

The Plan: My goal isn't just 10 or 20 common tools; I am building an engine to support thousands of niche calculators (Finance, Health, Engineering, Physics, etc.).

Current Status:

Live with the first batch of financial tools.

Clean UI, focused on speed

I know "thousands" sounds ambitious, but I've set up a modular structure that allows me to deploy new logic rapidly.

I’d love your feedback on the UX and suggestions on which "niche" calculators are currently missing from the web.
