Show HN: FishDex An offline fishing log built to show my students (opens in new tab)

I’m a teacher, not a professional developer. I’ve been trying to track my fishing life-list in Excel for the last year, but it was clunky and I eventually gave up.

I wanted to show my students that the "technical wall" shouldn't stop them from building tools they actually need. I "vibe coded" this entire app in about a day using AI to handle the syntax while I focused on the logic and the user experience.

The Goal: To prove that with modern tools, you can move from "spreadsheet fatigue" to a functional, custom application without a CS degree.

The App:

    100% Local: No sign-ins, no databases, no tracking. It uses IndexedDB to keep data on the device.

    Offline First: It’s a PWA, so it works on the water where there’s no signal.

    Open Source: I’ve put it under an MIT license so my students (and anyone else) can fork it and break it to see how it works.

I’d love feedback—not just on the code (which I know is AI-assisted), but on the utility. Is this a viable way to teach "Creation over Consumption" to the next generation?
