Connecting the Contour Blood Glucose Meter to Allie on Android

Last updated: October 16, 2026

Allie features Bluetooth integration with the Contour Next One Blood Glucose Monitor. This guide provides best practices to ensure seamless transfer of blood glucose data from the monitor to the Allie Android application.

Background

In order to pair the device, please make sure you have done the following during the installation process, completing all of the following:

  • Allowed Allie to turn Bluetooth on

  • Given Allie access to ""Location", Nearby Devices", and "Physical Activity"

  • Confirmed that Bluetooth is turned on for your phone

Note: If you have previously used the Contour Next One application, you will also need to delete that application from your phone. Then go to your Bluetooth settings and "Forget" the previously connected device. We also recommend restarting your phone before proceeding with the pairing.

For best results, we recommend making sure that you are using the most recent versions of Allie and that your phone's operating system is up to date. More information on checking your settings/updating Allie can be found here.

You will also need to make sure you see the blood glucose widget under My Health in Allie.

If you do not see this, please call us creating a support ticket in Allie: My Care -> Settings -> Technical Support (recommended). You can also try to send us an email support@codexhealth.com.

Pairing Contour BGM with Allie App

  1. To get started, please make sure the Contour Blood Glucose Meter is turned off. If it is on, hold the button down until it beeps and the screen goes blank.

  2. Then, open your Allie app, and go to the My Care tab using the bottom navigation bar.

  3. Select Devices & Integrations

  4. Then choose Blood Glucose Meters / CGM

  5. Select Contour Next One

  6. This will bring you to Step 1 - Make sure your meter is off and keep it near your mobile device.

    Go ahead and press/hold the button on your Contour until it looks like this image:

This will return you to the Devices & Integrations screen and you will now see the Contour Next One in a new Blood Glucose Meters / CGM section. You can now take your first reading.

Uploading Blood Glucose Readings to Allie

Now that the Contour is paired to Allie, your future readings will be automatically sent to Allie. They will then be visible for your healthcare provider.

To upload a reading

  1. Make sure that you have Allie open

  2. Insert a strip into the Contour. You should then see this screen indicating it is waiting for you to take a reading:

    If you do not see this screen when inserting a strip, please make sure your Contour is connected per the instructions above

  3. Apply blood/control solution to edge of strip. Try to use a single drop and make sure it is applied to the edge as best you can

    1. If the device beeps and shows you this image, it needs more blood/control solution to take a reading

  4. If the device is starting to take a reading, it will beep and show you a countdown

  5. Your current Blood Glucose will then be displayed on the Contour screen

Note: If you do NOT have context enabled in the Contour, Allie will ask you to add context instead.

Troubleshooting Issues with the Contour Next One

For general troubleshooting, please see here.

Cannot Take a Blood Glucose Reading

When you add your blood (or the control solution) to a strip that is inserted into the Contour, you should see a screen prompting you to add a small drop of blood to the strip.

In some cases, the amount of blood may be insufficient, in which case you'll see the following:

This indicates you need to add another drop of blood until you see the countdown which confirms the Contour is measuring your glucose levels. If you do not add enough blood within a minute, you'll see an "E1" error message indicating to try again with a new strip.

Additionally, if you see an E2 code when inserting a strip for the first time, this indicates there is an issue with the strip you've used.

Simply try another strip and you should be prompted for a reading.

Not Prompted When Inserting Strip into Contour
