You are on the right path here but I think you are missing the “big players” for lack of a better term. The prediction software available now (open source) is quite good and works with different types of CGMS and pumps. You are really going to want to look at Loop.
Loop basically collects the inputs in the app automatically for insulin if you use a pump. I’m on the Omnipod DASH and Loop works with a few, Omnipod being my favorite. You can also input injections. It can also collect CGMS data automatically from that system. It works with Dexcom and others (I think Libre). You manually input carbs, and you are still gonna do that based on VIBES. After that, you get these magic prediction lines that show you where you are headed. And with the pump, it can add or lower insulin amounts (closed loop mode

) to keep you in range. Pretty common to be 75-90% in range!

There's also Loop on the iOS side: https://github.com/LoopKit/Loop. I've been using it for 7 or 8 years. There's also several pumps that have closed loop capabilities built-in, but I've found that they try so hard to play it safe that they are less capable than running your own.
In How I keep myself alive using GolangHeh -- 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).
In Apple Makes Major Progress on No-Prick Blood Glucose Tracking for Its WatchAutomated insulin delivery app template for iOS
2 points · Open discussionMany people are controlling their insulin pumps via phone and watch apps: https://github.com/LoopKit/Loop
The app tries to predict blood glucose in the future (drawing on CGM, food intake, lots of parameters and other data) and based on that either automatically injects insulin, or asks the user to confirm.
People need to compile the app themselves because the liability in the case of adverse effects is insanely high.
It’s a highly driven community. I’ve seldom seen such a useful and well supported application of modern tech.

In Continuous glucose monitoring on the Apple WatchI would like to add that Control-IQ still underperforms open source DIY artificial pancreas systems like Loop (https://github.com/LoopKit/Loop).
The guys that built Loop and the Riley Link (https://getrileylink.org/) (bluetooth to RF adapter relay to control wireless pumps that were reverse-engineered) are heroes.
In A Smart Artificial Pancreas Could Conquer DiabetesIf you can to get the right pump, I highly recommend compiling one of these apps. Just wipes out all the competition from the commercial axis, truly life changing apps if you learn how to use them.
