Who Can Use It

Alternatives Worth Considering

If you’re exploring other continuous glucose-monitoring systems, the Dexcom G7 is a commonly suggested alternative with its own set of features and integrations. Compare device specs, alert options and data‑sharing capabilities to decide which system fits your daily routine best.
