I've been using Xdrip+ for 2 years now with the Dexcom CGM instead of their proprietary app. Works great and gives me the ability to export my data or sync it with a self hosted database if I so please. Why would I trust a corporation with my private health data when they have continuously shown that they will sell it or lose it to a hack the first chance they get.
I'm not arguing against the idea. I'm being realistic about what devs and users can do about this situation.
If you're lucky enough to find something that works, I'm not knocking that.
The world is your oyster if you have some self motivation.
The issue isn't anyone's ability to reverse engineer a glucose meter nor their "self motivation" to do so.
The issue is how outdated the expectations of some devs can be. The typical consumer will never use these apps because the whole topic is washed up. Software maintenance is a much steeper hill to climb than it used to be. Throwing an LLM at that just makes it more Sisyphean than it already was.
You can have fun, but this isn't helping anyone else defend their privacy. That angle is starting to become as embarrassing as the advice to save the planet by riding a bike.
