How a personalized care plan works

Step 1. Complete a questionnaire

The user undergoes a detailed questionnaire concerning the state of their health. The quiz contains questions about the user’s habits, health issues in the family, work-life balance, sleep quality, current symptoms, medications, physical activity, weight, nutrition, wellness, and physical activity goals that they wish to achieve with Patientory.

Step 2. Let the app process the input data

When the user has completed this step, Patientory embarks on processing and analyzing the input data to work out a care plan that will be tailored to the user’s health needs.

Step 3. Get your personal care plan

The Digital Health Coachplan assigns the patient different fitness activities (exercising, running, walking, cycling, swimming, etc.) for each day of the week and highlights how much time should be spent on them. As well as this, the personalized coach plan includes individual nutrition, meditation, and wellness plans that the user is also required to adhere to.

Step 4. Monitor your progress

The user can track their progress in a journal as well as modify how much time they wish to spend on a particular activity. If they decide to change their current care tips, they will have to wait for approximately 14 days and redo the quiz. The system will process new results and produce a new health score.

Got an idea? Let’s work together

Here’s what Patientory offers

To allow users to monitor their health status and lead a healthier lifestyle, we have developed and implemented a number of useful and practical features in the app.

COVID-19 tracker

The Patientory app tries to keep up with the times and adjust to its users’ changing needs. With this in mind, we’ve developed a COVID-19 tracker that allows individuals to enter their vaccination data and monitor their symptoms.

Personalized nutrition plan

The digital coach makes up a personalized nutrition plan that will define how many calories, proteins, fats, and carbohydrates the user should consume per day.

Individual fitness plan

The app provides the user with a list of physical activities (running, walking, cycling, and swimming) and exercises that they will have to perform throughout the day as well as pinpointing how much time needs to be spent on each of them.

Customized wellness plan

With a customized wellness plan, the user can track the amount of time spent on essential activities such as sleeping, meditation, reading, socializing, and hobbies. This enables users to look after their well-being and mental health.

Health score tracker

Users have the opportunity to enter their heart rate, blood pressure, weight, and body mass index (BMI) data into Patientory to track changes in their health and react to them quickly. Moreover, patients can share these stats with healthcare professionals to receive more effective treatment.

To maintain fluid balance in the body, the user can set up a water drinking tracker that will remind them to drink water. It’s possible to specify when and how often the user wants to be notified.

Photo diary

The photo diary enables users to keep fit and track their weight. The given functionality suggests uploading photos on a regular basis and comparing them over time to monitor progress and keep in good shape.

Elaborate health data collection mechanism

Our developers have integrated a sophisticated data aggregator mechanism that enables users to view and interact with all their medical records from different healthcare providers in one place. All they have to do is log in, select the desired provider from the list of Patientory’s partners, and wait for the app to gather the patient’s data from the organization.

Currently, Patientory has partnered up with thousands of care providers across the USA and is planning to extend the list. However, if the application doesn’t find any relevant information on the digital provider account, the user will be asked to connect with other organizations where they have their records or contact the provider’s support team to find them.

Notably, to ensure complete safety and transparency throughout the entire process, the app will require the user to confirm their credentials as well as undergo a KYC procedure. Once this stage is complete, the data will be safely stored on the user’s PTOYMatrix cloud storage.

In-app user storage

To safely store all the data in the app, the user will need to purchase in-app storage space. The storage itself is provided by Google Cloud Storage located in the PTOYMatrix blockchain.

Initially, the app provides 0.5GB of free storage space. If this is not enough, the user can purchase additional storage space right in the app. The payment is accepted in Patientory’s native currency which is called PTOY. Essentially, Patientory offers different subscription plans depending on how much storage the user needs. As well as this, the user can always clear their cache to free space for new data.

Payment options

  • A black icon of a wallet


    The user has the ability to top up their PTOY balance in the PTOYMatrix Wallet whose address syncs with their Ethereum Mainnet Wallet. To ensure interoperability between the two wallets, it’s necessary to install a 3rd party wallet, like Metamask, and export that wallet address to the Patientory private key which can be accessed in the Wallet settings section of the Patientory app.

  • A black icon of a heart

    Insurance subscription

    It’s possible to integrate health insurance right in the app to execute a one-time payment for the care plan subscription, provided that the given insurance company cooperates with the Patientory app. All the user has to do is enter the name of the insurance company, their member ID, insurance policy, and customer service number. The payment will be made automatically.

HIPAA compliance

HIPAA compliance was one of the most important stages in the entire app development process since the client puts the safety of users’ medical records first.

To ensure the highest protection and security of patients’ medical data, we conducted in-depth research on HIPAA compliance. We were tasked with compiling and reviewing a list of the particular deliverables that we as an IT company were accountable for.

PixelPlex’s experts carefully analyzed the underlying technologies, namely blockchain, Google Cloud, and IPFS. We produced a comprehensive report on HIPAA IT Risk Assessment outlining the technologies’ risk levels, the likelihood of threats, and current security measures.

Health is wealth. With regard to this, the Patientory app seeks to help millions of individuals worldwide maintain their physical and mental health and lead happy lives.

Rewards center

  • We all realize the importance of proper motivation. And so does Patientory.

    Our experts at PixelPlex oversaw the development and implementation of an elaborate rewards mechanism that will enable Patientory to draw more users to the platform.

  • The app comes with different rewards options that encourage users not only to adhere to their daily goals but also to go the extra mile!

    The rewards are paid in the form of PTOY tokens that can be smoothly transferred to the Ethereum wallet and traded.

Why does Patientory use blockchain?

  • The Patientory app relies on the PTOYMatrix blockchain network to facilitate smooth health information exchange and provide a robust data storage system that fully complies with the HIPAA.

    PTOYMatrix connects clinics, hospitals, researchers, and patients into a single information ecosystem and grants them an unprecedented level of transparency and more efficient communication.

  • Notably, PTOYMatrix ensures end-to-end encryption when transferring healthcare information, which shields the network from malicious actors and guarantees the maximum level of security for user data.

    In this video, Patientory CEO and Founder Chrissa McFarlane explains why the company has opted for blockchain and what benefits the technology can offer.
