With the Predict app, you can get a forecast of your upcoming glucose values so you can be prepared for highs or lows.1 It estimates where your glucose will go in the next 30 minutes, 2 hours, and during the night so you can stay ahead of potential changes.
-
- The Predict app requires an internet connection and CGM data from the Accu-Chek SmartGuide app to generate predictions.
- Make sure to enable notifications to get the most out of the Predict app.
There are three types of predictions in the Accu-Chek SmartGuide Predict app:
- Glucose Predict, which shows your estimated glucose levels for the next 2 hours.
- Low Glucose Predict, which notifies you if a low is likely to occur within 30 minutes.
- Night Low Predict, which shows your risk of having low glucose during the night.
How to read the Home screen
You can tap the button in the upper right-hand corner to switch to the Accu-Chek SmartGuide app.
Graph of predicted glucose values
See a graph of your predicted glucose values for the next 2 hours.
Most recent glucose value
See your most recent glucose value. The colour indicates whether you are in range.
Notifications
Your notifications will show up under your glucose values and are enabled by default. Tap the Menu icon, on the bottom right corner of the Home screen to see your Notification Settings.
-
- Check your Notification Settings as soon as you start using the Predict app. You can enable, disable, and customise notifications to meet your needs and preferences.
- Make sure to enable notifications for the Predict app in your iOS/Android settings. If you use Do Not Disturb or Focus modes, configure your smartphone settings to allow Predict app notifications.
- Notifications help you respond to events as they occur, whether or not you have the Predict app open.
Remember, you can always refer to the User’s Manual in the Help section of the Menu.
What to consider when using the predictive features
The Predict app generates predictions based on your CGM readings and carbs, and insulin data you enter in the Logbook. Some factors may not be “visible” to the Predict app or may change in the short term. Being aware of these possible changes can help you make safer decisions.
The Predict app can only make predictions based on the information it has collected
The Predict app cannot take into consideration:
Future actions you may have planned
- Meals
- Insulin injections
- Physical activity
Factors that have a delayed effect on glucose levels
- Physical activity
- Fat and protein-rich foods
- Alcohol consumption
Other external factors which may affect your glucose
- Medication
- Stress
- Illness
In these cases, pay close attention to your CGM values and act based on the changes in your blood sugar levels. Consult with your healthcare team if you need more information on how to manage these factors.
Carbs and insulin recorded in the Logbook can be factored into the predictions
- Carbohydrates and insulin recorded in the Logbook will be factored into the predictions, resulting in slight changes in your estimated glucose values.
- Predictions issued right after a meal or insulin injection may be less accurate when the respective data has not been logged. The predictions will update once the unlogged event affects your glucose, which takes at least 20 minutes.
Some of the predictions may be temporarily unavailable
You have just recorded carbohydrates or insulin in the Logbook
- The Low Glucose Predict will be unavailable for 20 minutes after you have logged carbohydrates.
- The Night Low Predict will be unavailable for 20 minutes after you have logged carbohydrates and/or insulin.
This gives the app time to update the prediction based on your intake. Carbohydrates need at least 20 minutes after consumption to have an effect on glucose levels.
You have low glucose (at or predicted to go below 3.9 mmol/L, or below your low glucose alarm threshold)
The Predict app will not provide any predictions when your glucose levels are low because you need to focus on stabilising them. The Predict app will indicate when you risk having low glucose, and you can always see your current glucose values so that you know what they are at all times.
There is no internet connection or no input from the CGM sensor and app
All predictive features are only available when your device has an active internet connection. This means that they will not work when airplane mode is enabled, or when no mobile network or wifi is available. If the supply of CGM data or communication with the CGM app is disrupted, the predictions may be unavailable.
-
- Your actual glucose values may differ from the predicted values.
- While the predictions are only available when you have an internet connection, the alarms from the SmartGuide app only require Bluetooth® between the sensor and your smartphone.
What is the difference between the predictions and the glucose alarms?
The predictions show when highs or lows are likely to happen, and the alarms notify you when your glucose actually goes above or below your defined limits.
Glucose predictions in the Accu-Chek SmartGuide Predict app
The Predict app estimates your upcoming glucose values. It is intended to provide insights in advance so that you can take appropriate action to keep your glucose level in the desired range.
You can look ahead and take action before a high or low occurs, instead of reacting to excursions when they happen.
There are three types of glucose predictions:
- Glucose Predict, which shows your estimated glucose levels for the next 2 hours.
- Low Glucose Predict, which notifies you if a low is likely to occur within 30 minutes.
- Night Low Predict, which shows your risk of having low glucose during the night.
Glucose alarms in the Accu-Chek SmartGuide app
The CGM app notifies you when your current glucose value is too high or low, so that you can take action to bring it back on track.
The alarm limits can be set and activated in the app. It will prompt you to take action when your current glucose value actually reaches a defined threshold, so they can be seen as a backup for the predictions.
There are three types of glucose alarms:
- Very High Glucose, which can be customised from 7.8-22.1 mmol/L.
- Low Glucose, which can be customised from 3.4-7.7 mmol/L.
- Very Low Glucose, which is set to 3.0 mmol/L and cannot be changed.
The allowed limits of your glucose alarms can be affected by your target range settings. For example, you can't set your low glucose limit higher than the lower value of the target range.
The predictions may help you to<sup>1</sup>
-
Prepare for changes in your glucose.
-
Reduce excursions before they happen.1
-
Spend more time in your target range.1
The alarms may help you to
-
React to changes in your glucose.
-
Stabilise your glucose levels.
-
Return to your target range.
While the predictions are only available when you have an internet connection, the alarms from the SmartGuide app only require Bluetooth® between the sensor and your smartphone.
