How to Connect Apple Health or Health Connect to GlucoPlot
Bring in glucose readings, steps, sleep, weight and workouts automatically so they sit next to your meals. Setup for iPhone (Apple Health) and Android (Health Connect), and what each one reads.
GlucoPlot works fine with nothing connected — you log meals and get an estimated response for each one. Connecting your phone's health platform is what turns the estimate into your actual numbers, and it's also how steps, sleep and workouts start appearing on the dashboard without you typing anything.
What GlucoPlot reads, and what it doesn't
Reads: glucose readings, steps, sleep, weight and height, workouts, active energy, and heart rate metrics (resting heart rate and variability) where your device records them.
Doesn't: pair with a sensor directly. If you wear a continuous glucose monitor, its own app writes readings to Apple Health or Health Connect, and GlucoPlot reads them from there. Everything stays on your device.
iPhone — Apple Health
Open Settings in GlucoPlot
Tap the settings icon, then find the Apple Health row. You may also be prompted to connect the first time you open a screen that would benefit from it, such as the glucose view.
Turn on the categories you want
iOS shows a permissions sheet listing each data type. Turn on glucose if you wear a sensor, plus steps, sleep, workouts and weight if you'd like those on the dashboard. You can leave anything off and change it later in the Health app under Sharing → Apps.
Give it a moment
Existing readings import in the background; you'll see a confirmation of how many came across. New readings sync automatically from then on, and workouts recorded on a watch show up on their own.
Android — Health Connect
Make sure Health Connect is installed
On recent Android versions it's built in. On older ones it is a free app from Google Play. Your sensor app, watch app or step counter also needs to be writing to Health Connect — check its own settings if nothing appears.
Tap Connect Health Connect in GlucoPlot
You'll find it in Settings, and the dashboard offers it when a card would fill in with it (steps, for example). Android opens the Health Connect permission screen.
Allow the data types you want
Choose glucose, steps, sleep, exercise, weight and so on, then allow. GlucoPlot pulls existing records in and keeps syncing afterwards. To change permissions later, open Health Connect → App permissions → GlucoPlot.
What changes once it's connected
- Meals get a measured response. A meal eaten while readings were flowing in shows your real curve under it and is marked as measured, rather than the estimate.
- Patterns get sharper. The Coach tab can rank your meals by what actually happened, and compare sleep, steps and workouts against how meals behaved.
- The dashboard fills itself in. Steps, sleep and workouts appear without logging.
If nothing is coming through
- Confirm the source app is writing to Apple Health / Health Connect — open the Health app and look for recent glucose or step entries. If they aren't there, GlucoPlot has nothing to read.
- Check that the permission is still granted; an OS update or a reinstall of either app can reset it.
- Sensor apps write readings with a delay — Dexcom's is about three hours by design, on both iPhone and Android — and some (FreeStyle Libre, in our experience) may not write to Apple Health or Health Connect. That lag is upstream of GlucoPlot. Details in how to pair a CGM with a food log.
