FIFA World Cup just kicked off, and instead of dealing with bloated sports apps that blast you with betting odds and spoilers, I decided to build my own companion app overnight using Claude Code.

Standard apps are completely overwhelming when you just want to follow a few specific teams. I wanted something hyper-focused for casual fans, so I built this with a few specific rules:

* **Instant Personalization:** Once you select your favorite teams, it automatically populates your calendar with all of their specific matches.
* **The "Watch" List:** If there’s a crucial game between other teams that impacts your group, you can add it to a "watch" list to keep an eye on tournament advancement.
* **Lightweight & Language-Ready:** It runs on 100% static data and lets you toggle seamlessly between various languages—no heavy APIs or tracking required, and auto-notifications keep you updated on kickoffs.

Right now, I'm just running a couple of test cycles on the web portal to smooth out the UX, but next is to expand this to smart display glasses next.
