Apple Health allows iOS Apps to share health data, including food and nutrition, insulin, blood sugars and exercise.
Food apps allow Jade to dose from hyper-accurate food data, without double-entry.
If Apple Health is enabled and you use a food App, carbs, protein, fat and fiber will be tallied over the last 15 minutes (if there is more than one entry) and defaulted automatically every time you open the Add Log screen. Also, when you manually add food data to Jade, it automatically places it into Health.
Blood sugars from Apps such as Dexcom, Spike, MiaoMiao and LinkBluCon allow Jade to both dose from and predict with the latest blood sugar readings, without double-entry.
Exercise data from Apps such as Nike, Strava, allow Jade to predict with accurate exercise data, without double-entry.
