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)

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.

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)

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.

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

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.

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 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 detects and notifies you if it is likely that you will have low glucose levels within the next 30 minutes.

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.

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.

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.

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 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 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'.

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.
