Frequently Asked Questions

General Questions

Are there any technical requirements to run the app?

The sensor app to be installed in parallel requires a smartphone with at least iOS 14.2 or Android 8 and the NFC function, which many modern smartphones support. If your smartphone is not compatible, please contact our support team. The Ebby app requires at least iOS 12 or Android 5.1.

Our product can be used before and during pregnancy, as well as while breastfeeding, making Ebby an ideal migraine prophylaxis for women who cannot take prophylactic medication due to pregnancy or the desire to have children.

According to the manufacturer, there is no evidence that using the sensor poses a risk to the unborn child.

Pregnancy and breastfeeding influence metabolism and blood sugar levels. Your metabolism may change again after pregnancy or breastfeeding. If this happens, you can undergo a new sensor phase with Ebby.

Ebby Therapy Content

What does Ebby exist of?

Ebby is an app that allows you to track your nutrition and migraine symptoms. The app also offers engaging educational lessons, recipes, relaxation techniques, exercise routines, and more.

Your starter kit provides all the necessary materials to measure and analyze your dietary habits and blood sugar responses.

Your starter kit includes:

  • A sensor for measuring tissue glucose
  • A user guide for easy setup and use

The Two-Week Sensor Phase

During the two-week sensor phase, accompanied by continuous glucose monitoring, you log your meals, and optionally, your physical activity and sleep. Migraines and headaches can be recorded at any time in the diary. Structured nutrition challenges help identify personalized dietary recommendations for stabilizing blood sugar levels.

Throughout this phase, you can monitor your body’s response to different meals directly in the Ebby app. Each logged meal receives feedback through a traffic light system, making it easy to see how your food choices affect your blood sugar. Personalized dietary recommendations help you make small, sustainable adjustments to prevent extreme blood sugar fluctuations, ultimately reducing headache and migraine days.

The Implementation Phase

Beyond the sensor phase, Ebby guides you digitally through your personalized therapy and helps you to implement small dietary changes. Through engaging educational lessons, you’ll gain valuable knowledge on managing migraines more effectively. The extended timeframe allows you to apply what you’ve learned to your daily nutrition while continuing to track migraines and headaches. You can also export your headache diary as a report to share with your doctor.

In addition to the nutrition diary, the app allows you to track migraine days and symptoms, medication, physical activity, sleep, and other lifestyle factors.

CGM Sensor and Sensor App

How do I apply the sensor?

Tissue glucose data is collected using a tissue glucose sensor. The application process is simple and consists of the following steps:

  1. Prepare the application site: Wash the area on your arm with mild soap, dry it thoroughly, and then clean it with an alcohol wipe, which is included in your starter package.
  2. Open the sensor packaging: Carefully unpack the FreeStyle Libre 3 sensor applicator and twist off the cap.
  3. Apply the sensor: Place the sensor applicator on the cleaned area of your arm and press down briefly. When applied, a thin, flexible, sterile filament is inserted just under the skin.
  4. Sensor is attached: Gently remove the applicator from your arm. The sensor should now be securely in place.

When starting the program in the app, the sensor application steps will be shown again with step-by-step images. Do not apply the sensor in advance! If you are using a different tissue glucose sensor, please follow the specific instructions provided for that device.

You wear the sensor for 10 to 14 days, depending on the manufacturer. During this time, you log your meals in the Ebby app and can monitor your blood sugar responses in real time. Additionally, each logged meal is rated using a traffic light system: red, yellow, and green indicate how well the meal supports stable blood sugar levels. This allows you to quickly assess your food choices and make adjustments accordingly.

The sensor patch can be applied over the sensor to improve its stability and ensure secure wear.

Please select mg/dL as your unit. The analysis in the Ebby app will also be displayed in this unit.

Threshold values between 60 – 180 mg/dL are suitable. The device will automatically calibrate itself within 24 hours. These values are general guidelines originally intended for diabetics, so you can ignore the threshold settings.

The device was originally designed for diabetics. If the displayed value is not below 55 mg/dL, you can ignore the alert. However, if your readings consistently show values below 60 mg/dL, please contact our support team.

Values above 180 mg/dL can occur after meals, especially after test meals. This is normal and not necessarily a cause for concern. If you have any questions about your values at the end of your sensor phase, feel free to contact us.

Yes, that is completely safe and not a problem.

Yes, the sensor is water-resistant for up to 30 minutes at a depth of 1 meter. It is also safe for use in seawater. Showering and sauna visits are no problem either.

No, applying the sensor is completely painless. It is placed on the arm using an applicator that works like a stamp. A small needle helps insert the sensor filament into the tissue but does not remain in the skin. The needle is barely noticeable during application.

If the sensor detaches or becomes defective, it cannot be reused, as the sensor filament cannot be repositioned, nor can the sensor be reactivated. Please contact our support team for assistance.

The sensor can be easily peeled off by hand, just like a bandage. This is quick and painless. After removal, you can clean the area with water and soap. Any adhesive residue can be removed with baby oil.

If your blood sugar drops rapidly at night and then rises again quickly, it is often because you were lying on the arm where the sensor is attached. This can interfere with the sensor’s readings. There is no need for concern in this case.

No, the sensor is a certified medical device and is not harmful to health.

The Sensor Phase

How should I eat during the sensor phase?

Plan Your Favorite Meals

Everyone has meals they are particularly curious about. Think about which ones interest you most and make a rough plan for when you’d like to test them. Consider breakfast, lunch, dinner, snacks, and beverages.

Eat a Variety of Foods

The Ebby sensor phase helps you discover the best meals for your body. If you usually don’t snack much, this is a great time to experiment. Try a diverse range of foods, including different side dishes like roasted potatoes, whole grain rice, or pasta, to maximize your insights.

Track as Much as Possible

Aim to log all meals in the Ebby app. If possible, weigh and enter each ingredient. If you’re short on time, simply take a photo of your meal—you’ll still receive personalized feedback.

More Calories Than Usual

To find your ideal personalized nutrition, you may consume more calories or carbohydrates than usual during the sensor phase due to test meals. That’s okay—think of this period as an investment in a healthier, more sustainable diet tailored to your metabolism.

Make Test Meals Simple

The test meals and challenges might seem overwhelming, but they provide valuable insights. Try eating individual foods separately and completing as many challenges as possible. Are you more of a bread or cereal person? Which types of fruit suit you best? Do you drink your coffee black or with milk? While experiments are important, don’t forget to include your everyday and favorite meals as well. Choose only the challenges that truly interest you or fit your current diet.

Yes, but keep in mind that the evaluation applies to the entire meal—for example, “jam toast with coffee.” Your blood sugar response to “jam toast without coffee” may be different, as coffee can have an individual impact on blood sugar. Try testing the same breakfast with and without coffee to see how it affects your metabolism.

Yes, accurate timing is important. If the meal time or blood sugar response is recorded incorrectly, the meal may not be evaluated properly, or the results could be misleading.

Your meal analysis is based on the data you enter. In general, the more precise, the better. If you’re on the go or can’t log every ingredient, you can simply take a photo of your meal. Our food database also includes ready-made dishes (e.g., lentil stew, spaghetti Bolognese), where average values are used for analysis.

Yes, all drinks—except water and unsweetened tea—should be logged just like meals. We analyze which beverages work best and worst for you. Use the test phase to compare your favorite drinks, such as regular vs. diet cola or apple spritzer vs. orange juice. Our data shows that beverages can affect blood sugar differently for each person.

Illnesses, including colds or other infections, often trigger the release of stress hormones, which can significantly impact blood sugar levels. It’s important to log the exact period of your illness under the “Well-being” category in the app. During this time and the following days, your blood sugar data may be skewed and cannot be used for analysis.

If a significant portion of your sensor phase is affected, please contact our support

Medications in our database are listed by their active ingredients. Check which active ingredients are in your medication and enter them in the app. If you cannot find the active ingredients, please contact our support team.

If you can’t find a specific food in the database, choose an alternative that closely matches what you ate.

Generally, there are no restrictions on taking supplements. However, you should avoid vitamin C tablets during the sensor phase, as they can distort the sensor readings. We recommend logging any supplements you take in the app.

If you’re eating out and can’t enter all the ingredients, simply take a photo of your meal. This way, you’ll still receive a meal evaluation. Additionally, our food database includes pre-made dishes (e.g., pizza, spaghetti Bolognese), which are analyzed using average values. You can estimate portion sizes accordingly. To assist you, the Ebby app provides helpful portion size guidance for many foods.

There are several reasons why a meal might not be evaluated:

•Is the connection between the sensor app and the sensor active?

Open the Libre 3 app to check. If the connection was interrupted, it may take a moment for the sensor readings to be transmitted again. The evaluation can only be calculated once the data is available.

•Was the baseline value undetectable?

In some cases, we may not be able to determine the baseline blood sugar level, making it unclear how much of the increase is caused by your meal. This can happen if multiple meals were eaten in a short period without a break in between.

If the issue persists, please contact our support team for assistance.

I can’t see my blood sugar curve in the Ebby app. What should I do?

To display your blood sugar curves in the Ebby app, the Libre 3 sensor app must be connected to the sensor, and your glucose data must be shared with us.

Follow these steps to share your data:

  1. Open the Libre 3 app by Abbott and go to the Settings menu.
  2. Select Connected Apps.
  3. Click on Connect to LibreView, then choose Connect with a practice.
  4. Enter the practice ID: perfoodgmbh and click Next.
  5. Our practice information should now appear on your list.
  6. Confirm by clicking Connect and then Done.

Note: To stop sharing your data, go to the same menu, select our practice, and click Stop Data Forwarding.

Please allow some time for the data to sync. If your curves are still not visible after 12 hours, please contact our support team.
