Apple Watch - Allows me to view my blood glucose at any time. Dexcom CGM - This is the best way to constantly measure your blood glucose, though it is a bit expensive. Rileylink - This is an open source hardware device which intercepts BLE packets from my continuous glucose monitor and sends reverse engineered 433mhz communications to my insulin pump. This has a companion app (Loop) which tells me projected blood glucose on my Apple Watch and automatically administers insulin accordingly. To a lesser extent, AirPods - it’s pretty cool to be able to say “hey Siri, what’s my blood sugar?” while I’m riding my bike. When I first got the Apple Watch + plus rileylink setup it was like Xmas every morning ; I got to wake up and look at how my blood sugar had been successfully controlled by the system through the night. Taken together, this open source loop/rileylink system was probably the first legit artificial pancreas used by diabetics in real life. All the other data like insulin on board and active carbohydrates was so exciting to have directly modeled and displayed on my watch since I had spent years trying to estimate those variables in my head throughout the day.
