DiaBLE VS Loop

My NFC class is used by most opensource and commercial apps like DiabetoLog but it requires a paid ADC annual membership to compile: https://github.com/gui-dos/DiaBLE/

It is technically possible to connect the Apple Watch directly to the FreeStyle Libre glucose sensors as demonstrated here: https://github.com/gui-dos/DiaBLE

Unfortunately, in this case you need to pay for a certificate for signing the app, build it yourself and so on

It is possible to reconnect to an European Libre 2 from any Apple device, even an iPad and a Mac (very probably even from an AppleTV but I didn't test it) like I am proving with my personal project https://github.com/gui-dos/DiaBLE.

it exists now (i use my iphone for DIY loop with dexcom G6 and omnipod dash) but you need to learn how to build the app yourself, apple will not allow something like this on the appstore. It's really great when you can get it to work https://github.com/LoopKit/Loop

I use the G7 and OmniPod together with Loop. It's great!

Heh -- Apple Watch + Loop (https://github.com/LoopKit/Loop) handles all my insulin dosing, so technically definitely a killer app that I can't live w/out.

I've turned off all other features/notifications on my Apple Watch, it just does this, and it's the most valuable product I use (since I no longer have to pull out an insulin pump in a meeting, look at some other screen to see glucose values, etc etc etc).

I am a person with Type 1 Diabetes (T1D). Knowing certain up-to-date data about my body is essential for a tight schedule of multiple daily precise treatments. Hence my opinion on the question is, of course, biased. I consider myself a T1D Cyborg, as parts of my body functions have been replaced through technology. I wear a blood glucose sensor and an insulin pump 24/7. I let an algorithm on my phone decide whether to administer a hormone that could be lethal if incorrectly dosed. I benefit from both sensors (in this case, the CGM) and actors (the insulin pump) connected to my body, and being readable and writable through APIs. Regarding my chronic disease, my available human APIs are a blessing to me.
