Stop doing napkin math after every dinner 🍕
I built a dead-simple Tip & Bill Split Calculator that runs in your browser—no installs, no tracking, no split-the-check drama.
Features the US diners actually need:
15 % | 18 % | 20 % one-tap presets + custom box
Auto-splits the total by head-count
Optional “round-up” so no one digs for quarters
Works offline, mobile-first, dark-mode friendly
Generate a downloadable card or share link in two clicks
Tech stack: vanilla JS + PWA manifest → 11 kB compressed, loads in < 200 ms on 3G.
Code is MIT on GitHub—PRs welcome if you want extra currencies or darker dark mode 😎
