What is Auto-Calibration?Auto-Calibration is a feature that simplifies the CGM calibration process. When you perform a blood glucose test on your paired meter, the app automatically uses that result to calibrate your CGM sensor — no manual entry needed.Your CGM calibration algorithm has not changed. Auto-Calibration only changes how the blood glucose value gets to your CGM: instead of you typing it in, the app receives it directly from your meter.Getting StartedHow do I turn on Auto-Calibration?Open the app and tap CGM Settings..Toggle Auto-Calibration to on.Once enabled, the next time you perform a blood glucose test on your paired meter, the app will automatically use the result to calibrate your CGM.How do I turn it off?Follow the same steps above and toggle Auto-Calibration to off. You will return to the standard manual calibration workflow. You can switch between auto and manual at any time.Do I need to pair my meter again?No. If your blood glucose meter is already paired with the app, Auto-Calibration will work with the existing pairing. If you have not yet paired your meter, go to Settings > Devices and follow the pairing instructions.How It WorksWhat happens when I do a blood glucose test?When Auto-Calibration is on:You perform a fingerstick test on your meter as usual.Your meter sends the result to the app via Bluetooth.The app checks that the value is valid.If everything checks out, the app calibrates your CGM automatically.You receive a notification confirming the calibration and the value used.The entire process happens in a few seconds after your meter completes the measurement.Does the app change my blood glucose reading before calibrating?No. The exact value your meter measures is the exact value used for calibration. The app does not modify, round, or adjust the reading in any way.Can I still calibrate manually?Yes. Manual calibration is always available, regardless of whether Auto-Calibration is on or off. You can access manual calibration from the calibration screen or by tapping "Calibrate Manually" in any failure notification.How do I know a calibration happened?You will see a notification that says something like: "Calibration: Auto-calibration complete. 120 mg/dL from [your meter name]." You can also check the calibration status on the app home screen, which shows when the last calibration occurred. For a full history, tap the calibration status indicator to open the Calibration History log.TroubleshootingAuto-calibration did not happen after my blood glucose testThere are several reasons this might occur:Bluetooth connection issue — Your meter and phone may have lost their Bluetooth connection. Make sure your meter is within range (typically within a few meters of your phone) and that Bluetooth is enabled on your phone. Try performing another test with the meter nearby.Auto-Calibration is turned off — Check that the feature is enabled in Settings > Calibration > Auto-Calibration.App was not running — The app needs to be running (it can be in the background) to receive data from your meter. Open the app and try again.Minimum calibration interval — If you calibrated recently, the app may delay the next calibration to protect accuracy. Wait for the cooldown period to pass and try again.In the meantime, you can always calibrate manually.I received a "Glucose changing rapidly" notificationThis means your glucose level was rising or falling quickly when you performed the blood glucose test. During rapid glucose changes, there can be a natural lag between your capillary blood glucose (what the meter measures) and your interstitial glucose (what the CGM measures), which can reduce calibration quality.What to do: Wait until your glucose level is more stable — ideally when the trend arrow on your CGM shows a flat or near-flat direction. Then perform another blood glucose test and the app will attempt auto-calibration again. You can also calibrate manually if you prefer not to wait.I received a "Calibration data expired" notificationThis means there was a delay between when your meter completed the measurement and when the data reached the app. This can happen if Bluetooth reconnected after a temporary disconnection, and the meter sent an older reading.What to do: Perform a fresh blood glucose test with your meter nearby and Bluetooth connected. The app requires data to be recent (within a few minutes) to ensure calibration accuracy.I received a "Meter not recognized" notificationThis means the app received data from a blood glucose meter that is not registered to your account. This can happen if there are other meters nearby, or if you are using a new meter that has not been paired.What to do: Go to Settings > Devices and check that your meter is listed and paired. If you have a new meter, follow the on-screen pairing instructions to register it. The app will only accept calibration data from your registered meter.I received a "Data integrity check failed" notificationThis means the data received from your meter was incomplete or could not be verified. This is usually caused by a brief Bluetooth interruption during data transfer.What to do: This is typically a one-time occurrence. Perform another blood glucose test. If the problem persists, try unpairing and re-pairing your meter in Settings > Devices.I received a "Value outside valid range" notificationThis means the blood glucose value received from your meter was outside the range accepted for calibration (typically 20 to 600 mg/dL). This could indicate an unusual meter reading.What to do: Verify your meter result. If the value seems correct and you believe it should be used for calibration, you can enter it manually through the manual calibration screen. If the value seems incorrect, perform another test with a fresh test strip and adequate blood sample.Calibration failed after the value was acceptedIn rare cases, the CGM may reject a calibration even though the blood glucose value itself was valid. This can happen if the CGM sensor detects an internal condition that prevents calibration at that time.What to do: Wait a short period and try again, either by performing a new blood glucose test (with Auto-Calibration) or by calibrating manually. If calibration continues to fail, consult the CGM troubleshooting guide or contact support.My CGM readings seem inaccurate after auto-calibrationIf you notice that your CGM readings do not match your expected glucose level after an auto-calibration:Check the Calibration History to see what value was used. Tap the calibration status on the home screen to open the log.If the value looks incorrect, perform a new blood glucose test and calibrate again (either automatically or manually).Make sure you are calibrating during periods of stable glucose, not during rapid rises or falls.If readings remain inaccurate after a fresh calibration with a confirmed correct blood glucose value, contact support.Frequently Asked QuestionsDoes Auto-Calibration change how accurate my CGM is?No. Auto-Calibration uses the same calibration algorithm as manual calibration. The only difference is how the blood glucose value gets to the app. In fact, Auto-Calibration may help accuracy by eliminating the possibility of mistyping a value during manual entry.Does Auto-Calibration work with any blood glucose meter?Auto-Calibration works with the blood glucose meter models that are compatible with the app. Your meter must be paired and registered in the app. Check Settings > Devices for a list of compatible meters.Can someone else's meter accidentally calibrate my CGM?No. The app only accepts calibration data from the specific meter registered to your account. Even if other meters are nearby, their data will be ignored.Does Auto-Calibration use more battery?The impact on battery life is minimal. The app uses the same Bluetooth connection that already exists for communicating with your meter. No additional background scanning is required.Will I be notified every time an auto-calibration happens?Yes. You will always receive a notification when auto-calibration occurs, whether it succeeds or fails. Success notifications are brief and will collapse after a few seconds, but remain accessible in your notification center. Failure notifications stay visible until you acknowledge them.What if I am in a meeting or sleeping and cannot check the notification?The app home screen always shows your current calibration status, including when the last calibration occurred. If a calibration fails and you do not acknowledge the notification, the app will send a follow-up reminder. If calibration becomes overdue, the calibration status indicator will change to a warning state.Can I undo an auto-calibration?If you believe an auto-calibration used an incorrect value, you can perform a new calibration (either auto or manual) with a correct blood glucose value. The new calibration will override the previous one.Is Auto-Calibration on by default?Yes, Auto-Calibration is enabled by default. You can turn it off at any time.

Glucose alerts can be critical to health and safety. By default, both iOS and Android suppress notification sounds when the phone is in Silent, Do Not Disturb, or Focus mode. To make sure alerts can still sound in these situations, please complete the setup below.Please read: Even after completing all of the steps below, smartphone alerts cannot be guaranteed to be 100% reliable. Please read the “Important Limitations” section at the end. This app should not be your only means of glucose monitoring and alerting.iOS (iPhone) Setup1. Allow Critical AlertsCritical Alerts are a special notification type provided by Apple that can play a sound even when your phone is muted or a Focus mode is on.When you first use the app, it will request “Critical Alerts” permission. Please choose Allow.To check manually: open Settings → BUZUD → Notifications.Confirm that Critical Alerts is turned on (green).Also confirm that Allow Notifications is on, and that Lock Screen, Notification Centre, and Banners are all selected.2. Turn On “Always Play Alert Sounds” in the AppGo to the relevant member’s detail page in the app.Turn on the Always Play Alert Sounds toggle.This setting helps alerts attempt to sound even in Silent or Focus mode.3. About Silent and Do Not DisturbCritical Alerts are designed to override the silent switch and Do Not Disturb.However, we still recommend not relying on Silent mode for extended periods. Where possible, keep your phone off Silent and at a sufficient volume during critical periods such as sleep.4. About Focus ModeEven if you add this app to a Focus mode’s “Allowed Notifications” list, the system may still block or delay alerts in some situations.We recommend: avoid enabling Focus mode during periods when you need to receive alerts; if you must enable it, add this app to that Focus mode’s allowed list, but please be aware this is not an absolute guarantee.5. Other RecommendationsKeep Background App Refresh on: Settings → BUZUD → Background App Refresh.Do not enable Low Power Mode, as it delays background notifications.Keep your phone volume at a level you can hear.Do not place this app in iOS 18’s “Hidden Apps” or under “Reduced Interruptions” blocking.Android Setup1. Allow Notifications and Set Highest PriorityOpen Settings → Apps → BUZUD → Notifications.Confirm the main notification toggle is on.Find the “Critical / Urgent Alerts” notification category and confirm its importance is set to Highest (Urgent).2. Grant “Do Not Disturb Access”To allow alerts to override Do Not Disturb, a separate permission is required:Open Settings → Notifications → Do Not Disturb → App exceptions (the exact path varies by device).Or follow the in-app prompt to grant “Do Not Disturb access”.Without this permission, alerts will not sound while Do Not Disturb is on.3. Allow Full-Screen and Lock Screen AlertsIn BUZUD’s notification settings, allow Lock Screen display and banners / pop-ups.If the system asks whether to allow “Full screen notifications / Full screen intent”, choose Allow.4. Disable Battery OptimizationAndroid restricts background apps, which can cause alerts to be delayed or silent:Open Settings → Battery → Battery optimization / App power management.Find BUZUD and set it to Don’t optimize / No restrictions / Allow background activity.5. About Silent and Do Not DisturbAfter correct setup, alerts should be able to sound during Do Not Disturb, but we still recommend not relying on Do Not Disturb for extended periods during critical times.Keep your media / alarm volume at a level you can hear.⚠️ Important Limitations (Please Read)Please understand the following points — they relate to your safety:Smartphone alerts are not 100% reliable. Even after completing all steps in this guide, alerts may still be delayed, silent, or undelivered due to operating system limitations, system updates, background mechanisms, network conditions, and other factors. This is a common limitation of all smartphone-based alerting apps, not unique to this app.Critical Alerts are not guaranteed to always play a sound. Under certain phone system versions or device states, a Critical Alert may not play a sound (the notification may still appear without any sound).Adding the app to a Focus mode allow list is not an absolute guarantee. Adding this app to a Focus / Do Not Disturb allow list improves the chance of receiving alerts, but the system may still block or delay them in some situations.Remote following (family / observers) relies on network push and is less reliable. Alerts received by observers depend on network and push services and may be missed due to network issues, push delays, or non-delivery. Remote following by family members cannot replace alerts on the wearer’s own device.Do not rely on this app as your only safeguard. Please combine it with routine glucose monitoring and other reminder methods, and perform a fingerstick glucose confirmation and any necessary medical action when an abnormality is suspected. If in doubt, consult your healthcare professional.If you still cannot receive alerts properly after completing this setup, please contact our support team and provide your phone model and system version so we can help investigate.
