ctqvva/JugglucoNG ? reverse-engineered prompt

Build me an Android app for continuous glucose monitoring with a clean Material 3 look and a modern dashboard. It should show the current glucose reading, trend, delta, and recent history, plus useful stats like time in range and simple reports. I want it to support several CGM systems, including Libre and Sibionics, and also be able to follow data from Nightscout or a direct HTTP source.

Please include alarms for low and high glucose, fast rising or falling values, sensor expiry, signal loss, and forecast warnings, with vibration, spoken alerts, and smart retry behavior so alerts are not missed. Add a journal for meals and insulin, with IOB and COB tracking, a simple dose calculator, and basic prediction of where glucose is heading. It should also be able to export and import data, sync with Nightscout, and share readings with other apps or another phone. If you need current implementation details, look up the latest docs online.
