Especially for those of us with no coding background, who can’t just build/edit an app.
For example, I like using Gadgetbridge to replace my fitness tracker app: https://gadgetbridge.org/
It’s not nearly as full-featured as a regular fitness app, but it literally can’t connect to the internet so there’s no way anyone can get my health info.
I was just looking into Waistline. I wonder if there’s a way to download the Open Food Facts database, keep it locally, and have the phone query that instead of the internet when scanning barcodes.
There’s a PR open for the feature, but doesn’t look like it’s actually been implemented yet.
