I built a "Zero-Guesswork" hub for chemical safety.

Most people "eyeball" dangerous chemicals.

Whether it’s bleaching powder for water or high-potency vinegar for deep cleaning, the common advice is usually "a glug of this" or "a capful of that." As a developer, that lack of precision bothered me—especially when "guessing" leads to ruined surfaces or chemical burns.

I built CleaningRatio to be the "Zero-Guesswork" hub for chemical safety.

The Goal: Replace confusing PDF charts and dangerous "eyeballing" with a suite of 6 high-precision calculators. I focused heavily on a minimalist, mobile-first UI because nobody wants to struggle with a complex app while they’re holding a bucket of bleach.

The Strategy:

I’m taking an "SEO-first" approach, targeting high-intent keywords that larger lifestyle blogs overlook. If someone is searching for a specific PPM calculation, they don't want a 2,000-word blog post—they want a result in 3 seconds.

I’m currently at the stage of optimizing for mobile engagement and preparing for AdSense. I’d love to hear from other utility-tool founders:

How do you balance "minimalist UI" with the need for enough text for SEO?

Is anyone else building niche "calculator-first" sites?
