What I built

A simple calculator that does reverse lookup – you pick the fish you want, and it tells you how to catch it.

Tech stack

  • Next.js
  • Tailwind
  • Cloudflare

The whole thing was built over a weekend.

What it does

  • Best fishing location for any fish
  • Optimal time and weather
  • Rod and bait recommendations
  • Works on mobile too

Did it work?

Yes. It reached page 1 of Google for “fisch calculator” within three days, which surprised me.

If you play Fisch, check it out:

Happy to answer any questions about the build.
