What tools (apps or other software) are missing?

I’ve spent my adult life building software for other people. Now that my child is T1D I have a cause that I want to build for. As I look for tools to help me and my child I have formed ideas about what is missing. I would very much like to hear about what other people think is missing.

An app that works with every CGMS and every glucose meter and every pump on the market and can import data from those devices and scan food labels into a digital log book. The app will analyze the patient’s record book, dosing regimen, CGMS data, and food info, then makes predictions on if/when hypo/hyperglycemia is likely to occur and make recommended dosing changes, etc. The app will also allow the patient to print out reports to take to the next physician appointment.
