Dexcom App vs GlucoHome: What's the Difference?
The Dexcom G7 is excellent hardware. The app that ships with it was built to keep you safe — not to help you understand your glucose. GlucoHome fills the gap.
First: GlucoHome is not a replacement for the Dexcom app
This is the most important thing to say upfront. The Dexcom app (and Dexcom Clarity) handles things GlucoHome doesn't: sensor warmup, calibration, Bluetooth pairing, the Share feature that lets a parent monitor a child's glucose remotely, and the alert system that keeps you safe when your phone is in your pocket.
If you use a Dexcom, you need the Dexcom app. GlucoHome connects to the same data via the Dexcom Developer API and gives you everything the Dexcom app doesn't provide — the clinical depth, the historical analysis, and the educational context that helps you actually understand what your body is doing.
What the Dexcom app does well
Dexcom's core strength is its real-time alerting system. The app delivers:
- Glucose readings updated every 5 minutes on your phone
- Urgent low alerts (below 3.1 mmol/L) with a distinctive alarm
- High and low threshold alerts you can customise
- Rate-of-change alerts ("falling quickly")
- The Share feature — so carers, partners, or parents can see your readings
Dexcom Clarity (the web companion) also provides PDF AGP reports, 30-day summaries, and the ability to share data with your clinic — though accessing it requires logging in and generating a report manually.
What GlucoHome adds
GlucoHome picks up exactly where Dexcom leaves off. Because GlucoHome connects to the Dexcom API, it receives the same data your Dexcom app does — but then applies a completely different layer of analysis and visualisation on top of it.
Where the data lives
When you use Dexcom, your glucose data is stored on Dexcom's servers. Dexcom's privacy policy governs that copy.
When you connect GlucoHome, readings and meal logs are also stored in the GlucoHome cloud database that runs this site. Traffic uses HTTPS. We may in future share de-identified, aggregated data with research or pharmaceutical partners, and we will notify users before this starts. You can export data from the app or email ktb@kl8tech.group to delete your account.
