Bio Counter

Bio Counter이란?

I was watching a YouTube video where the speaker said: "Find a tiny everyday tool, look at what makes it frustrating, and build a better version." That led me to bio counters. Most are stuck in 2012—ad-bloated, slow, and blind to how text looks on a phone. So I built a minimalist sandbox using Astro 5 & Tailwind v4. It gives you a clean 2-column layout with a live phone preview for 9 platforms. It even tracks multi-byte emojis perfectly via Unicode grapheme iteration so limits don't break!
