Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

Nothing special, but I didn't want to share my dietary habits with an unknown number of third parties, so I built my own calorie tracker. I didn't use anything fancy, I just ran Grist on my home server with a half dozen tables. Had to rewrite it a couple of times to support stuff like recipes, but it's good enough for my purposes. Didn't even need to add auth to it, I just use Tailscale on my personal devices to access the server from anywhere without exposing it to the internet.

That's very neat, any chance you'd be willing to open source it?

There isn't much there to open source, just a bunch of Excel-like formulas that progressively roll up data from ingredients to the final results for the day.
