There can be various reasons for identified glucose patterns. When the app determines the root causes of certain glucose patterns, it offers a few suggestions. However, you should always discuss your specific diabetes profile and the associated therapy with your diabetes care team before you make any comprehensive adjustments.

Also refer to 'How to use the Glucose Patterns Feature works'.

If you get a Night Low Predict notification, which predicts a potential nocturnal hypo, then there is a high chance (>30%) of having low glucose (below 3.9 mmol/L) during the night.

To minimise the risk of a nighttime hypo, either eat a snack containing complex carbohydrates (like a cereal bar) or prepare so you can react quickly during the night.

All treatment decisions should be discussed with your diabetes care team.

Also refer to 'How to use the Night Low Glucose Predict feature'.

If the Accu-Chek SmartGuide Predict app predicts a high (hyperglycaemic episode) within the next 30 minutes:
Consider doing some physical activity (e.g., going for a walk) or making an insulin correction to stay in range. If you have already injected bolus insulin, wait until the insulin comes to its full effect before you take further measures.

In addition to monitoring the excursion of the glucose prediction on the Accu-Chek SmartGuide Predict app, check the actual CGM value and monitor the course of the glucose carefully to asssess whether further action is needed.
All treatment decisions should be discussed with your diabetes care team.

If the Accu-Chek SmartGuide Predict app predicts a high within the next 31-120 minutes:
Wait and watch. Do not act upon this prediction now. Closely monitor your predictions and current glucose values. Note that glucose influencing factors like carbs intake, insulin injection, and activity can change the prediction again. Check your prediction in 30 min and then decide if exercise or insulin for correction is needed. All treatment decisions should be discussed with your diabetes care team.

If the Accu-Chek SmartGuide Predict app predicts a hypo within the general 2-hour glucose prediction range, then you can prepare and take appropriate actions to help avoid a potential hypo. It is crucial not to overreact. First wait and watch how your glucose level develops. Monitor your glucose levels closely so you can react in time. All treatment decisions should be discussed with your diabetes care team. 

Also refer to 'How to use the Glucose Predict feature'.

If your Low Glucose Predict feature is warning you about a potential hypo (hypoglycaemic episode), then the probability is very high that you will experience a hypo within the next 30 minutes.
Immediately take measures to avoid the hypo:

1. Eat or drink 15g of carbs, e.g., 100ml of juice or some jelly babies
2. Check your glucose after 15 minutes
3. If glucose remains below 3.9 mmol/L, take another 15g of carbs
4. Check glucose again after 15 minutes; repeat step 3 if glucose is below 3.9 mmol/L
5. Once glucose is back to normal, have a meal or snack (e.g., bread, fruits, yogurt)

You are advised to not change your overall therapy based on the data displayed without prior consultation with your healthcare professional. If you have questions about your therapy, contact your diabetes care team.

Also refer to 'How to use the Low Glucose Predict feature'.

Your past glucose values measured by your sensor are the main data used for generating your glucose level predictions and glucose patterns.

Your manual logs of carbs and insulin injections in your Accu-Chek SmartGuide app logbook and the timestamp of glucose values are also taken into account.

All prediction algorithms meet high performance benchmarks. Because the prediction is generated from past data, not all contextual data is covered by the predictive algorithm, which might affect future glucose values.

Additionally, if you do not log insulin and carbs correctly, there is a chance that the predicted information does not precisely reflect your actual glucose excursion.

The Accu-Chek SmartGuide Predict app detects and notifies you if it is likely that you will have low glucose levels within the next 30 minutes.

The Night low feature predicts the chance of you having low glucose levels that night (based on previous values), which allows you to decide what actions to take before you go to bed.

The Accu-Chek SmartGuide Predict app can provide an estimate of how your glucose may evolve within the next 2 hours based on data from the Accu-Chek SmartGuide sensor and the entries you manually add to your logbook in the Accu-Chek SmartGuide app.

The prediction includes the likelihood of your glucose values going low, going high, or staying in range. 

Disclaimer: please note that the Accu-Chek SmartGuide app does not take other factors into account (such as unlogged insulin or carbohydrates, physical activity, or alcohol consumption).

The glucose pattern detection feature identifies recurring events that happen in four defined time periods (morning, day, evening, night), and even the entire day, during the past week.

After data transfer occurs from the Accu-Chek SmartGuide app, patterns display at the bottom of the dashboard if the Predict app detects patterns in your CGM data. The goal of the pattern detector is to help you stay within your personal target range all day, every day.

You can download the Accu-Chek SmartGuide Predict app for free from the Google Play Store or Apple Store.

Yes, the Accu-Chek SmartGuide Predict app is available for both Android and iOS and supports these operating systems:

• Android 11 or higher
• iOS 15.3 or higher

Also refer to the User Manuals and Guides.

The Accu-Chek SmartGuide Predict app collects and uses information from the Accu-Chek SmartGuide sensor and CGM app (required) and offers predictive tools.

The main features are:

• Glucose Predict: general prediction within the next two hours
• Low Glucose Predict notification: hypoglycaemia prediction within the next 30 minutes
• Night Low Predict: predicts the chance of having a low glucose during the night (defined as a 7-hour time period)
• Glucose Patterns: automatic glucose pattern detection (a retrospective, not predictive, feature)

If your smartphone is in power-saving mode, the Accu-Chek SmartGuide apps may no longer be able to communicate with the sensor. A blood glucose meter for calibration and as backup is needed.

You can use two apps with the Accu-Chek SmartGuide sensor:

• the Accu-Chek SmartGuide app
• the Accu-Chek SmartGuide Predict app (uses the CGM data from the Accu-Chek SmartGuide app)

Yes, the Accu-Chek SmartGuide app supports the Apple Watch when used with our iOS app. The Accu-Chek SmartGuide app on the Apple Watch allows you to see your latest CGM value, a graph of your last 3 hours of data, and any relevant notifications. 

This depends on the settings of your phone and the permissions granted to the Accu-Chek SmartGuide app.

The app supports the use of features that allow the app to override Do Not Disturb or Focus modes if you choose to enable them. This feature is called Critical Alerts on iOS and Override Do Not Disturb for Android. The app prompts you to enable these settings during the initial setup, but you can also access them from the app menu at any time. If Critical Alerts or Override Do Not Disturb are disabled, the app notifications make sounds only if the phone is set to allow sounds.

If Critical Alerts or Override Do Not Disturb are enabled, the app notifications make a sound even if your phone is set to vibrate only or Do Not Disturb or Focus mode.

Yes, you can silence notifications and/or some warnings from the Accu-Chek SmartGuide app temporarily or set your smartphone to vibrate only.

You can disable Critical Alerts (iOS) or Override Do Not Disturb (Android) for the Accu-Chek SmartGuide app. When these settings are disabled, if you put your phone in Do Not Disturb or Focus mode, all app notifications are silenced temporarily while your phone is in that mode.

If the Critical Alerts or Override Do Not Disturb settings are enabled for the app, the app will override these modes and make sounds for each notification even if your phone is set to vibrate only or Do Not Disturb or Focus mode.

The app prompts you to enable these settings during the initial setup, but you can also access them from the app menu at any time. In addition, some alarms and notifications can be turned off entirely from the app menu. Beware that this will turn off the notification entirely and not just silence it. It will stay off until you turn it on again from the menu.

You can receive notifications from the app as cards on the app dashboard or as notifications on the home screen of your smartphone, if they are enabled. You can also receive notifications if you use an Apple Watch.

Alarm signals are received only if the sensor is connected to the app and you activate notifications. To receive information from the sensor, your paired smartphone must be within a range of 6 meters.

If you lose or break your phone and switch to a new phone, you must download the Accu-Chek SmartGuide app on your new phone and log in with your existing Accu-Chek Account. Settings (e.g., target ranges, units, etc.) and up to 6 months of data will be restored from your account to the new phone. This occurs during the first time use process, and when it is successful you are notified.

When the app is set up on your new phone, the next step is either to pair a new sensor or re-pair the current sensor that still has time left on it.

If your phone battery dies, the Accu-Chek SmartGuide app does not receive glucose data from the sensor or provide notifications while your phone is powered off. Charge your phone as soon as possible, power it on, and open the Accu-Chek SmartGuide app. When your phone is powered on again and the app is running, it will download data from the sensor.

If your phone was powered off for more than 8 hours, the historical data may show some gaps when displayed on graphs.

If you do not have mobile data or Wi-Fi access, the Accu-Chek SmartGuide app continues to receive data from your paired CGM sensor, displays your data, and sends notifications that you have set up.

These app features are not available-without mobile data or Wi-Fi access:

• data sharing with your Accu-Chek Account or healthcare provider (if sharing is set up)
• your recent data displayed in the Accu-Chek SmartGuide Predict app
• predictive features in the Accu-Chek SmartGuide Predict app

The Accu-Chek SmartGuide app receives new glucose values from the paired sensor every 5 minutes and is always updating to show the latest data. You should look at the CGM app at least as often as you would measure your blood glucose with a blood glucose meter. Also check your CGM value if you are not feeling well.

Discuss with your healthcare professional about when and how often you should check your glucose levels via your CGM app.

The Accu-Chek SmartGuide app can be downloaded for free from the Google Play Store or Apple Store (depending on your smartphone’s operating system).

Yes, the Accu-Chek SmartGuide app is available for Android and iOS.
The Accu-Chek SmartGuide app supports these operating systems:

• Android 11 or higher

If your smartphone is in power-saving mode, the Accu-Chek SmartGuide apps may no longer be able to communicate with the sensor. A blood glucose meter for calibration and as backup is needed.

You can use two apps with the Accu-Chek SmartGuide sensor:

• the Accu-Chek SmartGuide app
• the Accu-Chek SmartGuide Predict app (uses the CGM data from the Accu-Chek SmartGuide app)

There are 2 modes of CGM values: Trend Mode and Therapy Mode. The mode the sensor is currently in is indicated directly below the CGM value on the Home screen.

When the sensor is in Trend Mode the following applies:

• CGM values should not be used to make therapy decisions, such as insulin dosing.
• CGM values can be used only to see trends and as a general reference.
• To make therapy decisions, such as insulin dosing, test your blood glucose with your blood glucose meter.

When the sensor in is Therapy Mode the following applies:

• CGM values can be used to make therapy decisions, such as insulin dosing.

The sensor requires calibration to provide you with the most accurate readings possible:

• An uncalibrated sensor will be in Trend Mode. You can see CGM values but should not use them for therapy decisions.
• A calibrated sensor will be in Therapy Mode. You can use the confirmed values to make decisions (such as insulin dosing).

The sensor mode appears under the CGM value on the Home screen.

The calibration routine consists of two steps:

After a warm-up time of 1 hour, the sensor is in Trend Mode, and sends CGM values to the app every 5 minutes. Don't use these initial CGM values to make therapy decisions, such as insulin dosing. 12 hours after insertion of the sensor, the app prompts you to calibrate.

Step 1: Check your blood glucose and enter the glucose value into the app. The sensor goes into Therapy Mode. CGM values can now be used to make therapy decisions, such as insulin dosing.

Step 2: 30 minutes to 3 hours later, check your blood glucose again and enter the glucose value into the app. This is to confirm the first measurement. Note: If step 2 is missed, the sensor returns to Trend Mode.

The calibration routine is completed for the sensor.

To calibrate your sensor:

1. Check your blood glucose with your blood glucose meter, according to the manufacturer's instructions.
2. Tap Calibrate Now on your Home screen.
3. Enter the glucose value from your blood glucose meter in the Calibrate screen. The glucose value should be entered no later than 3 minutes after performing the test.
4. Tap Save.
5. Check that you entered the same glucose value into the app that was displayed on your blood glucose meter and tap Confirm. 

The glucose measurements of the sensor are more accurate if you calibrate at a point in time when your blood glucose level is relatively stable.

Do not calibrate shortly after a meal, after insulin administration, or after physical activity, and avoid environments with very hot or very cold temperatures, or rapidly changing temperatures.

If you accidentally entered an incorrect value, tap Cancel and enter the correct value.

Your sensor is calibrated.

Yes, the Accu-Chek SmartGuide sensor has an initial calibration routine, consisting of 2 steps.

If your feeling does not match the CGM values, check your blood glucose with an accurate blood glucose meter.
You can also change the sensor and/or contact your HCP when you doubt that your sensor is working properly.

To check that the CGM sensor delivers correct results, check your blood glucose with an accurate blood glucose meter at a time when your glucose does not change rapidly. To ensure that the sensor is working accurately, calibrate the sensor only in times of stable glucose levels and wash your hands before taking the blood sample from your fingertip.

Refer to 'How to pair the Accu-Chek SmartGuide sensor and app'.

Discard the sensor, as potentially infectious material, safely in a sharps bin following. For information on how to discard used components correctly, contact your local council or authority.

Other components of the pack can be discarded in domestic waste. A damaged applicator housing or an exposed sensor needle can cause injury. Discard sharp objects according to local regulations. Make sure that sharp objects don't cause injury to you and others.

Also refer to 'How to remove and dispose the sensor'.

1. Start peeling off the adhesive pad on the flattened side of the sensor.

2. Inspect the back of the sensor: Make sure that the sensing element of the sensor has been completely removed from the insertion site after removing it. Check the insertion site by using your finger or check it visually. If the sensing element remained in your skin or the application site feels unusual (for example, painful, swollen or red) contact your healthcare professional.

Also refer to 'How to remove and dispose the sensor'.

The sensor automatically stops working and stops sending data after the weartime of 14 days. About 24 hours and 2 hours before the sensor expires, the Accu-Chek SmartGuide app notifies you that the sensor expires soon and that you should apply a new one.

No, the sensor must be removed before entering medical treatment areas with high-powered medical electric equipment, for example magnetic resonance imaging (MRI), computed tomography (CT), X-ray, radiotherapy, or diathermia.
However, you can wear the sensor in the full-body scanners used at the airport.

Yes, the sensor is protected against the effects of temporary immersion in water at a depth of 1 meter for up to 60 minutes (IP28).

Refer to 'How to apply the Accu-Chek SmartGuide sensor'.

Apply the sensor only on the back of your upper arm. See the package insert for a picture of the correct insertion site.

The sensor has a diameter of 33.3 mm without the adhesive.The part of the sensor that sits below the skin is approximately 6 mm.

The Accu-Chek SmartGuide sensor should be stored at temperatures between 2 and 27°C, i.e. either in a shady place or in the refrigerator.

If you want to go swimming you can keep the sensor on your body. The Accu-Chek SmartGuide sensor may be submerged for up to 60 minutes at a depth of up to 1m. However, the adhesive can come off more easily in water, so using additional waterproof tape is recommended.

If you plan to spend time at high altitude, keep in mind that the Accu-Chek SmartGuide sensor is only guaranteed to work up to an altitude of 9,842 feet (3000 meters). Also clarify the allowable altitude for the blood glucose meter you are taking with you.

Keep in mind that physical activity has an effect on glucose levels, so it’s a good idea to regularly check your current level in the app when in doubt (e.g., when leaving the smartphone at the poolside when swimming).

When at the airport you can leave the Accu-Chek SmartGuide sensor on your body to pass through full-body scanners. Keep your medical certificate ready for any queries from security personnel. Spare sensors inside your luggage can pass through airport screenings as well.

Your sensor communicates with your smartphone via Bluetooth® Low Energy. On most airplanes, the operation of devices with active Bluetooth connectivity is now officially permitted. However, to be on the safe side, check in advance with the airline to see to what extent smartphone operation is permitted during the flight. During the flight, the smartphone must be switched to airplane mode.

When you turn on airplane mode on your smartphone, Bluetooth might automatically switch off as well (depending on your smartphone model). In this case, to re-establish the communication despite the active flight mode, follow the steps below to enable communication with Bluetooth between your sensor and your smartphone:

- iOS devices:
1. Open the Control Center.
2. Tap the icon for Bluetooth wireless technology to turn communication on.

- Android devices:
1. Open the quick settings by swiping down from the top of the screen.
2. Tap the icon for Bluetooth wireless technology to turn communication on.

Changing Time Zones:
If you travel to a different time zone, the time in your smartphone adjusts to the local time (as soon as you deactivate flight mode when you are travelling by airplane). The Accu-Chek SmartGuide app also adopts the local time for all displayed CGM values, so there is no overlap or duplication of CGM values. This is possible because the values are stored in the background in a universal time (UTC) and are adjusted automatically to the time zone you are in.

Yes, you can use the Accu-Chek SmartGuide CGM solution while travelling. Remember to pack a charging cable and/or a power bank to ensure that your smartphone always has power, especially during a long trip. Bring your blood glucose meter for calibration and as a backup.

Accu-Chek SmartGuide app
The Accu-Chek SmartGuide app continuously monitors your real-time glucose values from the Accu-Chek SmartGuide sensor and displays the information on your smartphone or smartwatch. The app receives, stores, and processes your CGM data wirelessly, via Bluetooth® Low Energy connectivity. You can customise your settings and glucose alarms.

Accu-Chek SmartGuide Predict app
The Accu-Chek Predict app collects and uses information from the Accu-Chek SmartGuide sensor.

The app enhances the Accu-Chek SmartGuide app feature set by providing you with an estimate of your upcoming glucose values and allows you to set reminders when certain pattern trends are revealed.

You can seamlessly transition between the apps using an app switch button available in both apps.

Every 5 minutes the CGM sensor sends glucose values to the Accu-Chek SmartGuide app. The app communicates with the sensor via Bluetooth® Low Energy. Each sensor has a wear time of up to 14 days and requires calibration using a blood glucose meter. The Accu-Chek SmartGuide  Predict app enhances this feature set by collecting and using data from the Accu-Chek SmartGuide app to enable glucose predictions and glucose pattern detection.

Though BGM (Blood Glucose Monitoring) and CGM (Continuous Glucose Monitoring) provide information about your glucose levels, there are some key differences:

Measuring frequency
The frequency of obtaining glucose values is different between using a BGM and CGM. Using a BGM, you might check your blood glucose levels several times a day, typically before meals and bedtime, depending on your type of diabetes and medication.

With CGM, your glucose level is measured continuously. The glucose values measured by the sensor in your skin are transmitted every 5 minutes and combined to create a glucose curve. You get a full picture of your glucose levels over the time you are wearing the sensor.

Measuring glucose levels in blood vs interstitial fluid
BGM and CGM also differ in where the glucose values are measured. BGM measures glucose in capillary blood drawn from your fingertips (or sometimes other places like the palm of your hand). The sensor of the CGM solution, in contrast, is placed in your skin, more specifically, in the fat layer below the skin (subcutaneous fat tissue). There, your glucose level is measured in the fluid between the cells (interstitial fluid, not blood).
