I've been working on and off on several smallish apps I use in the kitchen, purely non-commercial. I shared https://teig.pro https://teig.pro a few months ago and it's made substantial improvements since then. It's a recipe builder that recalculates masses on-the-fly and supports adding/editing ingredients -- especially focused on breads. Unfortunately Fly.io seems to have flagged the project and is preventing me from deploying updates without upgrading my account (which is already paid). There are quite a few bugfixes which will be rolled out once that issue gets resolved, or I change hosting. I also made https://pepcorn.pro https://pepcorn.pro quite a bit longer in a similar spirit, but much simpler. It uses your device's microphone to detect popcorn "pop"s, and measures the time between them -- done popcorn usually has ~5 seconds between pops.
