Product Manual

Clinical Trial or Beta Program
Spring 2022

Dear Parents,

Welcome to LittleOne.Care.

We wrote the Beta Manual in a way that allows you simple and immediate use of our solution alongside this short video to help you start using our product.

At the same time, please share with us if you need better clarification. Your input will enable us to improve and simplify the Manual for future parents who join the testers in the future.

Enjoy the reading and the video!


LittleOne.Care is developing a platform that includes a baby's wearable device, a cellphone application for parents, and Artificial Intelligence (AI) technology.

Our testing stages include Pilot (stage one), Alpha (stage two), and Clinical trial or Beta program (stage three). You can participate in the Clinical trial if you registered at Hadassah hospital. You can participate in the Beta program if you came directly through LittleOne.Care. It is important to note that no difference exists between the products, services, and applications of the two programs.


Participation in the Trials

Participation in the Clinical trial or the Beta program is for the benefit of parents' feedback, data collection, and performance improvement of the algorithms and AI we develop.

The box you received includes the following items:

  • One small wearable device for data collection

  • One grip ring for connecting the device to the shirt

  • One spare grip ring 

  • One docking station (only used for charging)

  • One USB-C connection cable between the docking station and the power source

We do not provide a power adapter. Any power adapter can be used for charging.

Application Set-Up

Click here to download the application

Choose your app store and follow the instruction to download LittleOne.Care application.

Adjusting the App 

During the Clinical trial and the Beta program, the app will undergo many changes according to the testers' feedback, progress in development, and new features. Firstly, some of the changes will be tangible and some will not be tangible. Secondly, some of the changes will follow your personal comments and some will not. Finally, the pace of changes will be rapid till you and the other beta testers will be satisfied.


Registering As a "Leading Parent"

The first parent who registers on the app is the "Leading Parent."Only one parent initially registers on the app. The responsibility of the Leading Parent is to manage all other users who will connect to the app later on.

Adding a New User to the App

  1. Enter the burger button in the top right/left corner

  2. Look for "Add a User"

  3. Follow the instructions to produce a dedicated link

  4. Each link can only be used once 

  5. If the link is not used within 24 hours OR the new user does not accomplish the registration process, the link will be closed. Then, the Leading Parent must generate and send a new link to the new user


Removing Users from the Application

At this stage, only LittleOne.Care admin can remove users. To remove users, the Leading Parent who first installed the app needs to submit a written request to remove users. To avoid mistakes, please provide the Leading Parent’s registered email, phone number, and baby's name.

Deletion of the App

Remove the app by long-clicking the LittleOne.Care icon on the home screen and following the removal instructions.

Removing Data

We are committed to your privacy and operate in the spirit of the General Data Protection Regulation’s (GDPR) stringent privacy policy.


If you would like to delete any information (beyond disconnecting the app), contact us and we will delete the file within one working day. This information consists of all accumulated data from the app. 


Because we are in a Beta program and ongoing development, we are not  GDPR compliant yet. However, we strive to improve our system by following the GDPR spirit and principles. 

Designing the Device 

The Consumer Product Safety Commission sets clear guidelines for the size and shape of any product or toy that is near or used by infants under the age of three. The size of the device must be large enough to prevent babies from swallowing it. Rest assured that the device you received from LittleOne.Care meets these requirements.


For more details about the standardization of devices used for babies under the age of 3 click here

Mitigating Harmful Transmissions and Radiation 

The design of the device does not emit transmissions when separated from the docking station. However, if the device is attached to the docking station, transmissions may be emitted. The only way to retrieve data from the device is when the device is physically connected to the docking station. This process occurs when the device is connected to the docking station, the docking station is connected to a power source, and your internet is active. 

Developing Water Resistance 

The device is not currently waterproof because the device is in the Beta stage and is not yet tested for standardization. Nevertheless, the future device will include water resistance. In addition, the future device will be suitable to handle a baby's dirty environment because of its easy-to-clean design. Until the development of a final waterproof device, in any case, where the device gets wet stop using the device and report it to us. We will replace your device. 

Testing and Standardization 

The Standards Institute in Israel approved the device for use in LittleOne.Care’s Clinical trial. However, the tests performed by the Standards Institute in Israel do NOT include the additional tests required for a commercial product intended for sale. The approval we received for the Clinical trial is NOT relevant for the Beta program, despite that the device is exactly the same. 


The product in your possession is NOT a commercial product and may not be sold or transferred to any other user without written approval from LittleOne.Care.


At the end of the Clinical trial and/or Beta program, we ask you to return the wearable device and any other parts you received during the period of the trial to LittleOne.Care's representatives.

Data Collection and Processing

Data Collection: Motion

The moment the device leaves the docking station it begins to collect any type of acceleration. The accelerations are in different directions and the final outcome is a long and detailed table of numbers. We developed algorithms and AI that learn to analyze these numbers and understand the meaning in terms of the baby's movements.


While charging the device, it uploads the acceleration data to the LittleOne.Care server. The data is processed, analyzed, and sent as your baby's life events and insights to your application. The analysis of the acceleration attempts to identify the quality of sleep, activity, lying position (tummy time), sitting, rolling, and more.

Because of your support and other Beta testers, we are continuing to develop capabilities for automatic detection and decoding of different and unique patterns of baby behavior. These behaviors include rolling, crawling, walking, diaper changing, and unique feeding and breastfeeding patterns.


Our goal is to improve the performance and accuracy of our algorithms for identifying the various situations and activities of the baby.


It is important to note that we continuously conduct various tests to improve performance. Therefore, we do not undertake the responsibility to send reports with accurate or consistent information.


During the Clinical trial and Beta Trial program, we will not include real-time reporting capabilities. These capabilities may include real-time emergencies, such as falls, shaking (SBS), bodily injury or the device does recognize moments. Any acquired information during the Clinical trial and Beta program cannot be referenced as a valid source to a third party. ​

Data Collection: Sound

We program our algorithms to detect the crying, laughing, and mumbling of babies. In addition, we program our algorithms to recognize when an adult talks, sings or shouts at the baby. 


Please note that our level of accuracy is constantly improving and we do NOT track the content of spoken, sung, or shouted words. Rather, we track the existence of the sound event.


Determining the Cause for Crying

In the next stage, we will analyze the reason for the crying. For the benefit of analyzing the baby's sounds, we collect sound recordings using the sound sensor in the device. In the next stage of the Clinical trial and Beta program, we will analyze the reason for the crying. We will attempt to accomplish this task by recording up to a four-second soundtrack of the baby and their surroundings.​

Implementing the Four-Second Soundtrack

We will use the recorded soundtracks solely to improve the algorithms of our solution. We upload the soundtracks and the baby’s motion data to the LittleOne.Care server in an encrypted and secure manner. We then convert the sound files into images. Our AI improves the ability to understand the reason for the baby’s crying by analyzing image segments of waves and sound energy.


Inside the four-second soundtracks, beyond crying, we may record other sounds that characterize your house or the environment. These sounds can include animal sounds, music from the TV, conversations, and car noises if you are traveling with your baby.


Our goal is to improve our performance in recognizing the baby's murmurs, laughter, and crying as well as the accuracy of recognizing the reason for crying alongside background noises.


The soundtrack processing and crying analysis are automatically performed after the data is uploaded to the LittleOne.Care server and without human involvement.


From time to time, the LittleOne.Care server asks for "help" in sorting the audible sound. In this case, a trusted agent will listen to random and anonymous soundtracks of a few seconds at most. If this event occurs, the trusted agent will not be able to associate the given soundtrack with any of the program participants.

Informing Others of Device Usage



The learning process is an interesting process that is constantly improving itself. The more data we work with, the faster the learning rate and the more accurate the results. 

Managing the Device’s position and attachment to a baby's cloth

Please keep the device in a fixed and consistent position and ensure it is balanced whenever possible. This maintenance will improve performance.

 Tagging Baby’s Life Events

Tagging Events Using the App

You can tag significant daily events through the app. To do so, enter the homepage of the app and tap on the icon of the selected event. Once completed, the event will appear on the Daily History page as part of the baby's event day on the date and time the event took place.


Discussing the Role of the Tagged Events

The baby's daily history automatically displays the baby's sleep, activity time, tummy time, rolling, crying, mumbling, laughing, and any other background noise. Throughout the day, event tagging is designed for you to document and add any other event or status that occurs during the day.

This document will provide you with a better understanding of the sequence of events and the relationships between them. For example, what caused the baby's crying? What contributed to the baby's deep sleep? When did you play or talk with your baby?


Tagging Accuracy and Insights

Tagging will improve the accuracy of our algorithms. For example, the performance of the feeding stimulus will enable us to teach our algorithms about the baby’s sucking movements and to independently identify that type of event.

Tagging Baby's Life Events in Real Time

On the homepage of the app, you have the ability to tag different events in real-time. The tagged events will be updated according to the number of tags performed, the age of the baby, and our algorithms' needs and accuracy.


We created an updated list of sample tagged events:

  • Diaper change

  • Start /End feeding/breastfeeding

  • Put your baby to sleep/wake up

  • Baby in an adult's hands

  • Stroller, hands, bath


The amount of tagging and its exact execution is important to us and will directly affect the quality of the information you receive back. Therefore, if tagging occurs by mistake, you can cancel / update  /change the tagging immediately or after its establishment by clicking on the cancel button or from the daily history report.

The Role of the Docking Station

The docking station has three functions:

  1. Charging the wearable device: Each time you connect the device to the docking station it will recharge its batteries

  2. Enables offloading data from the device: The docking station is responsible for uploading the data from the device to the LittleOne.Care server using your Wi-Fi network to process the data

  3. Enable updating algorithms on the device: The algorithm inside the device will be updated from time to time in order to improve its performance.

However, we will not make any functional changes (i.e., emergency reporting) without your prior approval at any point during the Clinical trial or Beta program. ​


Charging the Device

The final device is scheduled to operate for approximately three days without the need for recharging. However, during the Clinical trial and Beta program, the device will operate for up to 16-24 hours between charges. We also devote the device charging time to uploading data to the LittleOne.Care server. Therefore, we recommend choosing a fixed time of day to perform the daily charge; for example, while the baby is taking a bath. Once the device completes charging, your app will display a message reminding you to return it to the baby.

Uploading Data from the Device

To enable a smooth data upload, make sure that the device is attached to the docking station and connected to your Wi-Fi network. If no internet connection is present, you will not be able to upload the data or receive insights into your app. When the data upload process is successful you will receive an update on the app that states the data transfer was accomplished. 

If your cellphone is connected to the Internet, you should receive a daily update from your application a few minutes after receiving a notification saying the data has been successfully transferred. In case you do not receive a notification that the data has been transferred successfully, your cellphone app will not receive the accumulated daily information and your baby's life events.
