Sample Architecture of a Mental Health App

ScienceSoft's experts share an example of microservices-based architecture and outline its key building blocks.

Architecture of a Mental Health App

Head of Mobile Development

Microservices-based architecture is a good choice for complex mental health applications. Each service runs independently, so it's easy to deploy, scale, and maintain them separately. Also, if one microservice fails, this does not affect the other services.

Mental Health App Development Roadmap

During our 19 years in healthcare IT, ScienceSoft has realized over 350 diverse initiatives. Though each project is unique, it's still possible to define common steps and sample timelines. The roadmap we share below will help you better envisage your mental health app project.



From 4 weeks
  • Defining the goals and conceptualizing the app.
  • Analyzing the market, audience, and competitors in the relevant mental health care niche.
  • Assessing the feasibility of implementing the planned digital mental health intervention.
  • Listing and prioritizing the app features.
  • Identifying compliance requirements for the app (e.g., with HIPAA, HITECH, FDA, FTC, NCPDP, OCR, CFR 42 Part 2, GDPR, EU MDR).
  • Determining the types of personal data that will be collected, processed, and transferred by the app.
  • Modeling consent to process a data subject's information.
  • Planning data access control, data archival and clearing mechanisms, encryption for at-rest and in-transit data.
  • Helping decide on the data retention period.
  • Creating detailed Data Flow Diagrams (DFDs) to identify potential privacy issues.
  • Defining the required integrations.
  • Creating a business case, estimating the development cost and ROI.

Some mental health apps collect data for personal use only. If your app is no different, it is not subject to HIPAA compliance. But if your app gathers patient data and shares it with healthcare providers, insurance companies, business associates, or any other entity, you must comply with HIPAA.

MD, Healthcare IT Consultant


Requirements engineering and software architecture design

From 4 weeks (may run simultaneously with steps 1 and 3)
  • Determining functional and non-functional requirements for the app.
  • Creating compliance specification with references to pertinent clauses of standards and regulations (HIPAA, CFR 42 Part 2, etc.).
  • Translating regulatory compliance requirements into mental health software requirements.
  • Deciding on the resilient software architecture.
  • Designing the needed integrations.
  • Selecting a secure technology stack to support compliance with the necessary regulations and standards.

The visual accessibility of mental health apps makes a big difference for people who have vision impairments (e.g., blurred vision) caused by severe anxiety or depression. To enhance the app's visual accessibility, you may consider having your application integrated with assistive technologies like a screen reader or screen magnification software. Users may also benefit from the mental health app being integrated with alternative input tools such as speech input software or single switch entry devices.

Senior Business Analyst and Customer Service Consultant


Project planning

From 2 weeks
  • Selecting a project management approach (e.g., Scrum, Kanban).
  • Deciding on the project timeline, milestones, resources, and budget.
  • Defining tangible KPIs (e.g., user engagement metrics, such as daily active users, retention rate, and session lengths) for project health and progress assessment.
  • Evaluating the project risks, conducting Privacy Impact Assessment (PIA) of the app, analyzing PHI breach risks, and drawing up a risk mitigation plan.
  • Hiring or outsourcing the needed IT resources.



UX and UI design

From 2 weeks (may run simultaneously with steps 2 and 3)
  • Creating user personas and user scenarios (e.g., attending group therapy sessions).
  • Visualizing the app's core functionality via UI prototyping.
  • Mapping convenient user journeys and building UX wireframes.
  • UX testing.
  • Designing the visual interface of mental health software in accordance with the defined visual accessibility requirements.
  • Creating precise easy-to-understand consent forms and privacy policy that describes the data processing methods, data storage period, and third parties with access to the data.



Iterative development and testing

2–6 months for an MVP
  • Designing a secure development infrastructure compliant with HIPAA, GDPR, etc.
  • Setting up the environments for development and delivery automation (e.g., container orchestration, CI/CD).
  • Developing the app's front end and back end, following the OWASP guidelines on secure coding.
  • Implementing security features (e.g., encryption of PHI at rest and in transit, role-specific access control, multi-factor authentication).
  • Establishing PHI backup mechanisms, PHI breach detection, and breach notification processes.
  • Integrating the mental health app with the required devices, third-party apps, payment gateways, etc.
  • Conducting QA in parallel with the development.
  • Carrying out code review, compliance checks, static and dynamic application security testing, pentesting; resolving the detected vulnerabilities.

At ScienceSoft, we often offer MVP (minimum viable product) development as the first step. It helps to quickly validate the software idea, launch the product on the market, get early user feedback, and confidently evolve the product further.

Head of Mobile Department


Pre-launch activities and release

From 1 week to 6+ months (if certification is required).
  • Revising the project documentation for consistency and certification compliance, e.g., with ISO 13485 and IEC 82304-1:2016.
  • Conducting a HIPAA compliance assessment or GDPR compliance audit (if necessary).
  • Obtaining approval from FDA.
  • Carrying out the final review of security controls in the mental health software infrastructure and preparing an incident response plan.
  • Rolling out the app's pilot version to the focus group to get feedback and introduce improvements, if needed.
  • Launching the application.

If your mental health app has SaMD features, an additional step must be taken during the pre-launch phase: submitting the rolled-out pilot to the regulators. If they respond positively, the app can go to the market. Also, if your app introduces new treatments, clinical trials should be conducted first.

Senior Business Analyst and Healthcare IT Consultant


Maintenance and evolution

  • Implementing updates for full compatibility with new OS versions, managing user issues, optimizing cloud resource consumption, performing security audits, and more.
  • Adding new mental health app features and integrations, adjusting UX and UI as needed.
  • Planning software migration to a HIPAA-compliant cloud (e.g., AWS, Azure).
  • Re-designing the app architecture for PHI protection improvement.
