I can't synchronize my data or I don't see my sleep or activity data inside of the app

If your data isn’t showing in the app, here are a few quick steps to ensure proper synchronization between your Circular Ring and the Circular app.


1️⃣ Check Connection & Airplane Mode


First, make sure your ring is connected to the app:


If Airplane Mode is turned on, your ring won’t sync.

  • Open the Circular app and look at your Sleep and Energy Circles. If they are grayed out, you are likely in Airplane Mode.

    To turn off Airplane Mode:


  • Tap the Airplane Mode icon in the quick-access bar at the top of your homepage.


  • You can also find it under the menu (☰) in the top-left corner of the app.


2️⃣ Syncing Your Data


Once Airplane Mode is disabled, your ring will automatically sync a few seconds after connected to the app.


  • You can also manually trigger a sync by doing a pull-down gesture (swipe down) on your Circular app home screen.



3️⃣ Understanding the Sync Steps


The app follows four steps during synchronization:


  1. Ring ➜ App – The ring sends data to your phone.
  2. App ➜ Server – The app uploads your data to the Circular cloud.
  3. Server ➜ App – Your data is processed and returned to your app.
  4. Display – Your updated data is visible in the app.


Each step may take a few seconds. You’ll only see your new metrics after Step 4 is complete.


🔧 If the sync gets stuck at 0% or any other percentage:


  • Make sure your phone is not in Power Saving Mode that can limit Bluetooth functionality.


  • Try again by killing the app (swipe up from background running app) and restarting it.


  • Go to My Ring > Manage my devices > Tap the red ❌ > Delete the ring from your phone’s Bluetooth list.
  • Then, reconnect the ring by setting it up as a new device in the app.


4️⃣ Do I Need to Leave the App Open?


Nope! 🙌
Once your data has synced and you’ve viewed it, you can safely close or kill the app — the data will remain saved and updated.
