Connecting the Omron SC-150 Scale to Allie on iOS

Last updated: October 16, 2026

Background

Allie features Bluetooth integration with the Omron SC-150 commercial weight scale. This guide provides best practices to ensure seamless transfer of weight data from the scale to the Allie iOS application.

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

  • Given Allie access to Bluetooth

  • Allowed Notifications from Allie

  • Turned Bluetooth ON for your phone

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 weight 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 Instructions

  1. (Optional - Turn the scale over and insert the batteries into the battery compartment.

    1. The scale display will quickly flash and then go blank - you may not see this)

  2. Make sure the scale display is blank. In Allie, go to the My Care tab using the bottom navigation bar.

  3. Select Devices & Integrations

  4. And then choose Scales

  5. Select the Omron SC-150

  6. This will take you to Step 1 - Insert 4 "AAA" batteries in the back of the scale.

This will return you to the Scales screen. If you have issues at any point in time with the pairing process, please start over from the beginning.

Please wait for the scale screen to go blank before proceeding with taking your weight.

How to Take a Weight Measurement

  1. Launch the Allie app

  2. Stand on the scale

  3. The display will fluctuate until it determines the weight. At this point it will flash three times.

  4. You should then see the Bluetooth icon below your weight measurement

    1. If you do not see the icon, make sure that Allie is open. If it has closed, open it, and the weight measurement should come through soon

  5. The reading will then be sent to Allie shortly afterwards (it may take a few seconds to synchronize). 

If you take your weight but Allie is not currently open, the measurement may not show up in Allie. To address this, open up Allie and tap the Bluetooth button on the SC-150. This should send any recently saved readings from the scale to Allie.
