Dexcom ONE+ sensor — a next-generation continuous glucose monitoring system with a built-in transmitter. Apply the sensor, and in 30 minutes you’ll see your glucose level on your smartphone in real time: no scanning, no calibration, no routine finger pricks.

Key benefits

• All-in-one: sensor and transmitter combined in one compact device — nothing extra to buy.
• 10 days of wear + a 12-hour grace period for replacement after the session ends.
• Only a 30-minute warm-up — the fastest start among CGM systems.
• No calibration: the system doesn’t require scanning or test strips.
• Personalized alerts for high and low glucose levels.
• Three insertion sites to choose from — rotate them to let your skin rest.
• Water resistance: best in its class — showers and swimming are no problem.
• Accuracy during fluctuations: reliable readings even during rapid glucose changes.
• Event logging: track how food and physical activity affect your sugar levels.
• Sharing: share your readings with loved ones — up to 10 people via the Follow app.

How ONE+ differs from Dexcom G7

Same working principle, built-in transmitter, 10 days per sensor. There are two differences, and both matter when choosing.

Simpler setup. For ONE+, installing the app is all it takes — the system just works. For Dexcom G7, besides installing the app you also need to deal with the Country of Residence setting — an extra step involving a location workaround.

Pump integration. ONE+ does not work with insulin pumps. If you need it to work with Omnipod 5 or Tandem t:slim X2, choose the Dexcom G7 sensor instead.

If you don’t use a pump and rely on injections, ONE+ gives you the same level of control at a lower price and with a simpler start.

Who it’s for

People with type 1 or type 2 diabetes who want to move from finger pricks to continuous monitoring. Suitable for adults and children from age 2 (after consulting a doctor). This is often the first step into CGM: start with a single sensor, and if the system works for you, the monthly kit is better value.
