You just finished checking your blood pressure or stepping on your Qardio scale, and you expect to see the data pop up in Apple Health. But nothing shows up. The numbers stay stuck in the Qardio app, and your Apple Health app looks like it has no idea the reading ever happened.
This can be really frustrating, especially if you count on Apple Health to keep all your health data in one place. Doctors, fitness apps, and even your own peace of mind depend on accurate, up to date records.
In this article, you will learn exactly why this sync problem happens and how to fix it yourself. Most of these solutions take just a few minutes, and you can try them right from your couch.
What Happens When Qardio Stops Syncing
When Qardio and Apple Health stop talking to each other, your health readings get trapped. Your blood pressure numbers, weight, or heart rate stay inside the Qardio app but never make it over to Apple Health. This means any other app or service that pulls data from Apple Health will show gaps or outdated information.
The sync between these two apps works through something called HealthKit. Think of HealthKit as a bridge that lets different health apps share information with each other on your iPhone. When the bridge works, data flows smoothly from Qardio to Apple Health. When something blocks that bridge, your readings pile up on one side and never cross over.
Leaving this problem unfixed can cause bigger headaches down the line. If you track trends in your blood pressure over weeks or months, missing data points will throw off your averages and charts. Your doctor might rely on these records during checkups too. Gaps in the data could lead to incomplete health pictures, which nobody wants.
One more thing worth knowing: the sync usually happens automatically in the background. You should not have to do anything after taking a reading. So if you find yourself manually checking whether data transferred, something has gone wrong that needs your attention.
Qardio Not Syncing With Apple Health: Common Causes
Before jumping into fixes, it helps to understand what usually causes this problem. Knowing the root cause often points you straight to the right solution.
1. Permissions Got Turned Off
Apple takes privacy seriously, and that means apps need your permission to write data to Apple Health. If Qardio lost its permission for some reason, it cannot send any readings over.
This can happen after an iOS update, when you restore your phone from a backup, or if you accidentally toggled something off in your settings. The Qardio app might be working perfectly fine on its own, but without the green light from Apple Health, the data stays locked inside.
Sometimes people turn off permissions while cleaning up their privacy settings and forget they did it. A quick check in your Health app settings will tell you if this is the issue.
2. The Qardio App Needs an Update
App developers regularly release updates to fix bugs and keep things running smoothly with the latest iOS versions. If your Qardio app is outdated, it might not communicate properly with Apple Health anymore.
Apple changes how HealthKit works from time to time, and older app versions might not know how to handle those changes. Updating to the latest version often solves sync problems without any extra effort on your part.
3. Background App Refresh Is Disabled
Your iPhone has a feature called Background App Refresh that lets apps do work even when you are not using them. Qardio needs this feature turned on to sync data in the background after you take a reading.
If Background App Refresh is off for Qardio, the app can only sync when you actually open it and wait. Many people turn this feature off to save battery, not realizing it affects how their health apps work.
The fix is simple once you know this is the cause. A quick trip to your iPhone settings can get things moving again.
4. A Software Glitch Is Blocking the Connection
Sometimes apps and phones just get confused. Temporary glitches can block the communication between Qardio and Apple Health even when all your settings look correct.
These glitches can happen after installing new apps, running low on storage, or even after your phone has been running for a long time without a restart. The good news is that these issues usually clear up with some basic troubleshooting steps.
5. Your iPhone’s Date and Time Settings Are Wrong
This one surprises a lot of people. If your iPhone’s date or time is incorrect, it can mess with how apps sync data. Health readings get timestamped, and conflicting timestamps can cause Apple Health to reject incoming data.
This issue pops up most often when people travel across time zones or manually change their date and time settings. Switching to automatic date and time usually clears this up fast.
Qardio Not Syncing With Apple Health: How to Fix
Now that you know what might be causing the problem, let’s get it fixed. Work through these solutions one by one until your sync starts working again.
1. Check and Reset Apple Health Permissions
Start by making sure Qardio has permission to write data to Apple Health. This is the most common fix and takes less than a minute.
Here is what to do:
- Open the Health app on your iPhone
- Tap your profile picture in the top right corner
- Scroll down and tap Apps
- Find and tap Qardio
- Make sure all the data types you want to sync are toggled on
If everything was already on, try turning all the toggles off, waiting a few seconds, and then turning them back on. This resets the connection and often kicks the sync back into gear.
After doing this, open the Qardio app and take a new reading or manually sync your existing data. Check Apple Health to see if the new reading appears.
2. Update the Qardio App
An outdated app is an easy fix. Head to the App Store and check if Qardio has any updates waiting.
To update:
- Open the App Store
- Tap your profile icon at the top
- Scroll down to see pending updates
- If Qardio appears, tap Update
Once the update finishes, open Qardio and try syncing again. Developers often include sync fixes in their updates, so this step alone might solve everything.
3. Turn On Background App Refresh
Without Background App Refresh, Qardio cannot sync data unless the app is open on your screen. Turning this feature on lets the app work quietly in the background.
Go to Settings on your iPhone, then tap General, then Background App Refresh. Make sure the main toggle at the top is set to Wi-Fi or Wi-Fi & Cellular Data. Then scroll down the list and make sure the toggle next to Qardio is green.
After enabling this, give it some time. Take a new reading with your Qardio device and wait a few minutes before checking Apple Health. The sync should happen automatically now.
4. Restart Your iPhone
A simple restart fixes more problems than most people expect. Restarting clears out temporary glitches and gives your apps a fresh start.
To restart, hold down the side button and volume button together until you see the power off slider. Slide to turn off your phone, wait about 30 seconds, then hold the side button again to turn it back on.
Once your phone boots up, open the Qardio app first, let it load completely, and then check if your data syncs to Apple Health. This basic step works surprisingly often.
5. Fix Your Date and Time Settings
If your date and time are set manually, switching to automatic can solve sync issues related to timestamps.
Open Settings, tap General, then tap Date & Time. Turn on the toggle for Set Automatically. Your iPhone will pull the correct date and time from the network, and your apps will use matching timestamps.
After making this change, try syncing your Qardio data again. If mismatched timestamps were the problem, this should clear it up right away.
6. Reinstall the Qardio App
When nothing else works, a fresh install can help. Deleting and reinstalling the app clears out any corrupted data that might be causing problems.
Before you delete, make sure your Qardio account has your data backed up to the cloud. Your readings should be tied to your account, not just stored on your phone. Once you are sure your data is safe, press and hold the Qardio app icon until it wiggles, then tap the minus sign to delete it.
Go to the App Store, search for Qardio, and download it again. Log back into your account, and the app will pull your data from the cloud. Set up the Apple Health permissions fresh, and try syncing again.
7. Contact Qardio Support
If you have tried everything above and your data still refuses to sync, it might be time to reach out for help. Qardio has a support team that deals with these issues regularly, and they can look into problems specific to your account or device.
Visit the Qardio website or check the app for contact options. Have your device model, iOS version, and app version ready when you reach out. This information helps them troubleshoot faster and get you back on track.
Wrapping Up
Getting your Qardio device to sync with Apple Health again usually comes down to checking a few settings and giving your phone a quick refresh. Most people find that permissions, app updates, or a simple restart does the trick.
Your health data matters, and keeping it all in one place makes tracking so much easier. With these fixes in your back pocket, you can get things working smoothly again and focus on what really counts: staying healthy and informed.
