# Building Things, Spending Money: iPhone Duo Stock Alert

9 Nov 2026

In this week’s reminder that “*you can just build things now*”, I got tired of waiting till January for my iPhone Duo order, and I didn’t want to spend $30 for alerts on a website, so I made a tool to get alerts for iPhone Duo for in-store pick-up.

Unfortunately for my wallet, it worked.

I adapted from a couple other existing repos out there, and cleaned things up so you could, in theory, point your agent at this repo, prep the free ntfy app (sends push notifications), keep a machine with NodeJS running (or use Cloudflare; free tier should work), and you should be able to get fairly up-to-date notifications whenever the local Apple Store has a Duo of your choice in stock.

Check it out at [this GitHub repo](https://github.com/yjsoon/duo-stock-tracker) (point your agent at it).

You still need some level of tech knowledge to set it up, but if you’ve tried just a bit of agentic building, it should be doable! Let me know if you need help setting it up, and I can yell at my agent some more to make the instructions clearer.

You really can just build things now.
