In this letter we will explain to you what this all about and what apps you will be using.

Please use the following three apps* during the next 2 months:

1. mylife Smart App

This has the same functions as the mylife App. It was only renamed for this Proof of Concept. You can continue to connect and read out your mylife YpsoPump and the mylife Unio Neva.

2. mylife Carb Estimator

SNAQ supports you in determining the carbohydrates of meals. The app is named mylife Carb Estimator. You can take a photo of your meal and will then receive a suggestion for the amount of carbohydrates. You can use the estimate in the bolus calculator (currently this must be entered manually in the bolus calculator).

Please visit:

3. mylife Advice

The mylife Advice App will be installed in the background of your smartphone. After a certain time period, the xbird App will be able to provide information using the sensors integrated in the smartphone (orientation, acceleration, position, etc.) and the therapy data from the mylife SmartApp. The app will then start to send you notifications.

When you do sports, it is important that you carry the smartphone on you if possible.

You can use the mylife YpsoPump as usual for bolus delivery after you have calculated the bolus in the mylife Smart App. To do this, you also use the SNAQ mylife Carb Estimator App to use the carbohydrates calculated there and validated with your own estimate.

*The unreleased apps can only be tested with an iPhone (version 7 or later).

This is what it comes down to:

Important: For all suggestions and values, please consider whether they are right for you. If you have doubts, we recommend a check (e.g. own estimate of the carbs in g or a calculation of the carbs).

This Proof of Concept is intended to show that artificial intelligence can positively support the everyday life of pump users. For example, in the form of automatic carbohydrate determination or also, thanks to bespoke instructions, in everyday activities. Using on the sensors in your smartphone, it is possible to recognise activities and to provide appropriate information or reminders together with therapy data.

During the 2 month period, you will have the opportunity to give us feedback three times via an online survey. Your feedback is extremely important to us, as it also serves as a basis for deciding whether we are using the right technologies.

How to download the apps:

TestFlight by Apple: This app is available from the App Store and must be installed. This app from Apple provides you with the three test apps.

You will receive an invitation from Apple TestFlight for the apps to appear in TestFlight. The invitation will be sent to the e-mail address connected to your AppleID.

Next step: Setup of the apps

After all three apps have been installed, they still need to be set up.

mylife SmartApp

The setup of the pump and blood glucose meter works in exactly the same way as with the official mylife App. There are no changes here.

mylife Carb Estimator

The app needs your consent to read glucose and insulin data from Apple Health, as well as gain access to the camera to take photos of meals. To receive reminders, permission for push messages can be granted as an option. If you use a BGM, FGM or CGM with the capability of transferring the glucose data to Apple Health (e.g. Dexcom G5 or G6), you can allow the transfer to Apple Health within the BGM, FGM, CGM app, so that the mylife Carb Estimator can read the data and link it to the meals.

Note: If you are using the carb values for your therapy but are not sure about the result, we recommend that you compare this with your own estimate, or by weighing the food.

mylife Advice

It is important that you give the xbird App all permissions. Location data should also be collectable in the background - this has little effect the battery. However, the app helps us to “learn” how patterns can be recognised in connection with the collected therapy data. This way, notifications and notes are customised for you. The mylife Advice App learns from you and remains passive for the first 4 - 6 weeks. Thereafter you will receive occasional notifications which will be related to your everyday life.


Health App

It is important that all apps have read and write access in the Apple Health App for:

  • Blood glucose
  • Carbohydrates
  • Insulin data
  • If possible, all other accesses should be granted for the mylife Advice App.

To check/set this, go to the iPhone settings -> Privacy and select the Health App there.

Frequently asked questions

General questions

How long will the Smart Advice Proof of Concept Study last?

The Smart Advice proof of concept study will last for two months.

Start date: January 12, 2021
End date: March 9, 2021

How many survey questionnaires will there be during the study?

There will be Total three survey questionnaires during the study. The first at the beginning of the study, the second after about 6 weeks and the last at the end of the study.

Can I fill out my Surveys on iOS, Windows, etc.?

Yes, you can complete your surveys on all major browsers and operating systems (iOS and Windows).

Why does no text appear in the app?

Activate the Dark mode in the iOS Settings.

mylife Carb Estimator

What can I do with the app?

The app supports you in understanding your blood glucose levels in connection with your meals. 

  • Record a meal to get carbs, fat and protein values
  • For each past meal see your postprandial glucose profile, Time-In-Range as well as highest/lowest reading 3 hours after the meal
  • Automatically sync carbohydrate values with the mylife smart app
  • Discover and learn which meals influence your glucose to be either low, high or in-range
  • Find out what happened last time when you had the same or similar meal 

Please note, that for many of these functionalities it is needed to have your CGM data stored in Apple Health and allow the mylife Carb Estimator to read it.

Where can I find a tutorial on how the app works?

You can find a video tutorial on how the app works here: English: Deutsch:

How to best record an image?

We recommend holding your smartphone parallel to the table with a distance of about 30 centimeters. So that the full plate as well as some areas of the table are on the image.

How is the weight determined?

You can take pictures using two ways: With 3D analysis and without 3D analysis. When using the 3D analysis, the weight gets calculated using the 3D camera, which is available in newer iPhones. When the 3D Analysis is not active, the portions are based on standard portion sizes.

What is the “3D analysis”?

When using the 3D analysis, we use the 3D camera available on specific phones to create a three-dimensional model of the food. We use this information to calculate the weight of the food. If the 3D analysis is inactive, we use common portion sizes.

Which smartphones support the 3D analysis?

The following models support the 3D analysis when using the selfie-camera: iPhone X, iPhone XS, iPhone XS Max, iPhone XR, iPhone 11, iPhone 11 Pro, iPhone 12, iPhone 12 Mini. The iPhone 12 Pro and iPhone 12 Pro Max have the 3D cameras on the back of the phone and therefore the 3D analysis is always active.

What to do when I don’t find an item in the database?

When your search did not match a food item in our database please:

  • Check the spelling
  • Add the main ingredient first and add other ingredients separately
  • Avoid using special characters
  • Search for a more general term

In case these tips did not help you can report the missing item to the developers. It is planned for adding additional national food databases for after the pilot phase.

How can I add meal components which have not been detected?

You can add a meal component manually if it has not been automatically detected. Click on the three dots in the top right corner and click on “Add food” to add the meal component manually. With your finger draw the area around the meal component which should be added. You will see a red line indicating the drawn area. Click on “Add food” in the bottom right corner to add the meal component.

How can I change wrongly detected meal components?

The app automatically selects ingredients if it is confident enough that the selection is correct. If the app selected a wrong ingredient, clicking on the “(-)” button removes the selected ingredient. After it is removed, the correct ingredient can then be selected from the list of proposed ingredients or searched for in the entire database by clicking on the “Search” button.

How can I duplicate an already existing meal?

In the home screen, swipe a meal card to the left to reveal the copy meal button. Your meal will be copied to the current time.

How are similar meals proposed?

The similar meals in the meal analysis screen are proposed based on the ingredients in the meals and based on the food group to which the ingredients belong. For example, in the meal analysis screen of a meal consisting of white rice and chicken, meals are proposed which either contain white rice or chicken. Additionally, meals of which the food group of the ingredients are the same as the food groups of white rice (which has food group rice) or chicken (which has food group white meat).

Where can I change the amount of carbohydrates?

To change the amount of carbohydrates of a meal component click on the pen which is on the same line as the weight and the carbohydrates. A screen appears with a slider for each ingredient. Moving the slider changes the weight of the ingredient. As you move the weight slider you will see the carbohydrate amount changing as well. Click on “Confirm” in the bottom right corner to confirm the new weight and carbohydrate amount.

Carbohydrates do not appear in the smartApp

First check, if the carbohydrates appear in Apple Health under Browse (Entdecken) -> Nutrition (Ernährung) -> Carbohydrates (Kohlenhydrate).

If the Carbohydrates do not appear in Apple Health, check the permissions of the Carb Estimator and smartApp in the iPhone Settings App (Einstellungen) under Health -> Data Access & Devices (Datenzugriff & Geräte) -> Carb Estimator / smartApp.

Carbohydrate values are wrong in the smartApp or some values are not imported

In the Carb Estimator App, carbohydrates are saved to Apple Health when going back to the home screen after having recorded a meal. However, the meal must have been recorded no later than 5 minutes ago (that means for example when setting the date for a meal to 2 hours ago, carbs are not being saved).

When adapting a meal (e.g. the weight or the date), carbohydrates are also not being saved again, so try to make sure that your information is correct before saving the meal.
