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.

Dexcom ONE+ is an innovative continuous glucose monitoring (CGM) system from Dexcom, featuring a set of three sensors that provides rapid, convenient, and highly accurate real-time glucose tracking without frequent finger pricks or sensor scans.

What makes Dexcom ONE+ stand out?

• Sensor and transmitter in one
  A streamlined design combines the sensor and transmitter in a single compact device, eliminating the need for separate components and simplifying the installation process.

  Unlike some CGM systems that require lengthy prep times, Dexcom ONE+ is operational just 30 minutes after insertion.

• No finger pricks or scanning
  There’s no need to manually scan or calibrate the system with a meter; data is automatically transmitted every 5 minutes. You can still do an occasional check with a standard glucose meter for reassurance, but daily finger pricks are no longer necessary.

  Set custom notifications for high or low glucose levels, as well as for rapid rises or drops. This allows you to respond quickly and maintain better control of your glucose.

• Multiple insertion sites
  Dexcom ONE+ can be placed on various body areas (in accordance with the manufacturer’s and your healthcare professional’s recommendations), most commonly on the upper arm or abdomen.

• Reliable water resistance
