A list of the Apple Operating Systems (iOS) and Android Operating Systems compatible with each Dexcom app are available at dexcom.com/compatibility
Dexcom limits the compatibility of new Dexcom app updates with old versions of Apple Operating Systems (iOS) and Android Operating Systems. At a minimum, Dexcom intends on supporting the current major OS version, plus the previous version for each platform. New OS versions often include privacy and security improvements and additional phone features that can offer users a better experience.
To help ensure that you have the best experience with your Dexcom apps, we recommend following these guidelines:
- Check the Dexcom compatibility chart before installing a new iOS or Android OS version on your smart device. Dexcom tests all its apps on new OS versions after the OS is released. It may take several days or more to complete testing and, if necessary, update the Dexcom app to be fully compatible with a new OS version. We recommend waiting on installing a new OS version until we approve it, because your Dexcom app may not work properly upon the initial release.
- Before updating to a new version of a Dexcom app, ensure that your smart device is running on the latest supported OS. Some new app features may only be available with the latest OS. OS requirements will always be noted in the App Store and in the “What’s New” content within the app.
- Finally, don’t forget to check the compatibility chart before purchasing a new smart device to use with your Dexcom apps.

Yes, you can check your CGM information on your wrist! The Dexcom G5 Mobile App supports Apple Watch and can be used to discreetly view your glucose reading, trend arrow, and trend graph. Use the digital crown to scroll the trend graph view between 1, 3, or 6 hours of data.
You can also view your number and arrow as a complication on your watch face. You can choose from four complication styles depending on your preferred watch face.
To set up Dexcom G5 Mobile on your Apple Watch you’ll need to use the Watch app located on your compatible iPhone. To add complications, use the Watch app to choose the watch face and complication style that you want. If you would like the color of your Dexcom complication to reflect your glucose status, choose the multicolor option for the watch face.
See your Apple Watch instructions for more detail on setting up an app on the watch.
When you wake your Apple Watch, it syncs your current CGM data from your compatible iPhone. There may be a brief delay before your watch app or complication shows current information. Place the Dexcom G5 Mobile app in the Dock and turn on background app refresh for best performance.
Your Apple Watch will only communicate with your compatible iPhone, not the Dexcom G5 Transmitter. You will not receive alerts, alarms, and other notifications on the watch unless it is connected with your compatible iPhone. For example, if you have your watch on and you go out, but leave your iPhone at home, you will not receive any CGM updates.
Compatibility:
Dexcom G5 App v1.6 and Apple Watch running watchOS 3 or later required. US only.

Dexcom tests all apps on new OS versions, including public betas, after the OS is released. It may take several days or more to complete testing and update the app to be fully compatible with a new OS version. Dexcom recommends checking our compatibility chart before installing a new OS version on your smart device, and not installing the new version until we approve it.
If you have installed a beta OS version on your smart device and need to revert to a commercially available version, consult your OS developer’s instructions at the below links:
We encourage you to not install any beta OS version on your smart device while you are using it to run a Dexcom app.

Having problem with the sensor pod not sticking? Before inserting the sensor make sure your skin around the insertion site is free of creams, lotions, or perfume. After cleaning the area with alcohol wipes, let it dry completely. Still having problems? Put medical tape (such as Blenderm, Tegaderm, IV 300 or 3M tape) over the sensor pod’s adhesive patch, making sure you don’t tape over the transmitter.

Anytime you have a new transmitter, make sure you start the pairing process by entering the serial number into your receiver or compatible smart device before inserting the transmitter into the transmitter holder on the sensor. Pairing can take up to 30 minutes. You will know the transmitter and receiver are paired when the Bluetooth icon stops blinking. You can then start your new sensor session.
Still having issues?
- Did you clean your sensor site with a topical antimicrobial solution, such as isopropyl alcohol and the transmitter with a damp cloth or alcohol wipes?
- Did you keep the safety lock on the sensor applicator until AFTER the sensor applicator was secure to your skin?
- Did you keep your fingers ABOVE the collar when pushing the white plunger completely down the applicator barrel?
- After pressing the white plunger completely down the applicator barrel, did you then move your fingers to BELOW the collar and pull the collar completely up the applicator barrel?
- Is the transmitter serial number correctly entered into the receiver or compatible smart device?
- Is the transmitter completely snapped into the transmitter holder on the sensor?

If you’re using a Dexcom G5® Mobile CGM System and you noticed that you missed a notification but didn’t get a Signal Loss Alert, double-check your smart device* settings and the sound settings in the app.
Your alarm and important alerts can notify you with sound even when:
- The device volume is low.
- The device is on Mute, Vibrate, or Do Not Disturb.
You always get a visual notification, but you may not hear sound on your first notification. Unless you clear an alarm or alert, it repeats at half volume after 5 minutes, and at full volume every 5 minutes after that.
Important: If you have chosen Vibrate-only as your sound setting for an alert, that alert will never make a sound. The G5 app cannot override most wired and Bluetooth headphones or other accessory devices. Do not assume you will hear alerts when accessories are connected to your smart device.
As always, make sure the smart device and transmitter are within 20 feet of each other, with nothing blocking the transmitter’s signal.

The signal loss alert tells you when your receiver or smart device isn’t communicating. This may occur if you (and the transmitter) are too far from your display device or something is blocking your transmitter signal, causing you not to get sensor glucose readings.
LBL013382 Rev002 -
The Bluetooth off alert means this function is turned off. Bluetooth must be on in order to display glucose information on your device. Refer to your smart device guide to turn on your Bluetooth.
LBL013382 Rev002 -
The question marks mean that the transmitter does not understand the sensor readings for the moment. You will want to wait at least three (3) hours for them to clear. If they do not clear within that time frame, please contact our Technical Support for further assistance.

This screen means you recently entered a calibration blood glucose value and the sensor is having trouble calibrating. Follow the directions on the screen to enter a finger stick reading in 15 minutes to restore readings.

- 1. Go to the menu in the G5 Mobile app
- 2. Choose Settings
- 3. Choose Health
- 4. Tap the Enable button to enable sharing CGM data with the Health app
- 5. Tap the slider for “Blood Glucose” on the health access screen

To pair your transmitter with your smart device*, you will need to enter your transmitter SN number. The transmitter SN is a series of numbers and/or letters that can be found in the following locations:
- On the transmitter box label – the transmitter ID number is the same as the SN number on the box
- On the bottom of the transmitter - the transmitter ID number is the same as the SN number on the bottom of the transmitter
The app will guide you to enter the SN number by taking a photograph of the barcode on the bottom of your transmitter box, or by typing in the SN.
After entering the SN successfully, you will be prompted to insert the sensor and attach the transmitter. From there, wait up to 30 minutes for your smart device and transmitter to connect.
You can only set your transmitter ID when you are not in a sensor session. If you are in session when you attempt to pair a new transmitter ID, the app will ask you if you wish to stop the current session. Selecting STOP SENSOR will end a sensor session you may have with a current working transmitter.

We recommend checking the Dexcom compatibility chart before installing a new iOS or Android OS version on your smart device and before acquiring a new phone for use with your Dexcom system. If you use a smart device or OS version that isn’t listed in the compatibility matrix, your Dexcom app may not work properly and you risk missing alerts and alarms and/or not seeing your CGM data. Dexcom tests all its apps on new OS versions and devices after they are released. It may take several days or more to complete testing and, if necessary, update the Dexcom app to be fully compatible with a new OS version or new phone.
