Accessibility apps are proving to be a boon for users with particular problems. They are designed to help elderly and disabled people in making their lives more comfortable. These applications help users perform specific tasks and manage their daily activities without relying on others.
As with most accessibility mobile apps, there is always a carefully planned app development and technology stack. Choosing more appropriate technologies helps to avoid problems related to interconnection and compatibility. It also helps with scalability, security, and cost optimization.
In this blog, we share important considerations for creating a tech stack for accessibility mobile apps and best practices for its development.
Key Considerations for Developing Accessibility Mobile Apps
Accessibility mobile apps must be designed to meet specific user needs and objectives. Below are some critical considerations for software development:
1. User-Centric Design:
All accessibility mobile apps should remain accessible to everyone, implying that they should incorporate applications for the physically challenged, those with low vision, and the elderly who have difficulty hearing. Programming languages such as Flutter help build interfaces for devices that are both portable and easy to use.
2. Performance Optimization:
The user in a low network coverage area or a user with smaller screen devices must be given the same feel as a well-running app. This means that API and data management systems must be designed to enhance performance.
3. Security:
Maintaining user privacy is essential, particularly regarding members of sensitive groups. Some security risks can be managed by employing backend frameworks such as Spring Boot, while content security can be managed with a built-in security feature.
4. Scalability and Maintenance:
In order to stay relevant, mobile apps need further updates and features. A scalable architecture ensures that app development grows naturally as user adoption rises. Java’s threading characteristics make it ideal for scaling up CPU-bound workloads.
5. Cost Efficiency:
The costs of the hosting infrastructure can be significantly high. Hence, expenses can be restrained by employing cloud options, such as AWS, and by placing EC2 servers and RDS databases in one available region.
Steps to Build the Right Tech Stack
Backend Software Development
The backend serves as the mobile app’s brain, handling logic, data processing, and integration with other systems. The Mobility Assistant platform uses Spring Boot for its backend. It offers:
- Scalability: Supports growing user bases with efficient resource management.
- Built-in Security: Provides default mechanisms like authentication and encryption, which can be tailored to fit specific needs.
- Java Strengths: Ideal for handling CPU-intensive operations and ensuring consistent performance.
Database Selection
Databases store and manage the mobile app’s data. For accessibility apps, it’s vital to ensure the database structure supports quick data retrieval and secure storage. The Mobility Assistant uses MySQL, a fixed-structure relational database, which ensures:
- Clear business functionality with structured schemas. .
- Compatibility with ORM tools like Hibernate, simplifying data mapping and access.
Frontend Frameworks
The frontend is the mobile app’s interface—the part users interact with directly. Choosing the right frameworks ensures accessibility and responsiveness.
- Mobile Application: Flutter can be a great option due to its cross-platform capabilities, allowing developers to build native-like apps for Android and iOS from a single codebase.
- Admin Panel: Consider Angular, as it ensures dynamic and feature-rich dashboards for administrators to monitor and manage app functionalities.
Cloud Hosting
Cloud infrastructure provides the flexibility and reliability needed for modern apps. The Mobility Assistant can leverage AWS, with key components hosted on:
- Elastic Compute Cloud (EC2): For scalable backend hosting
- Relational Database Service (RDS): For managing the MySQL database
- Hosting these in the same availability zone reduces communication latency and costs.
Addressing Software Development Challenges
Even with a solid tech stack, developers often face hurdles that require innovative solutions. Here are some challenges encountered during the Mobility Assistant’s development and how they can be resolved:
1. API Optimization:
In low-network areas, ensuring app functionality can be tricky. Developers can optimize API responses to transmit only relevant data. For instance, at the entity model level, fields not set by the user can be excluded from the JSON response.
2. Infrastructure Costs:
Hosting on AWS can become expensive without proper planning. By consolidating resources within a single availability zone, you can minimize inter-zone communication costs.
3. Deployment Strategy:
Deploying a live application requires careful coordination. You can ensure smooth rollouts by taking comprehensive backups, including databases, before any major deployment. This practice mitigates risks and ensures business continuity.
Best Practices for Accessibility Application Development
When developing accessibility apps, adhering to best practices ensures success. These include:
- Prioritize Accessibility Standards: Follow Web Content Accessibility Guidelines (WCAG) to make your mobile app usable for all.
- Adopt Agile Development: Iterative development allows teams to adapt quickly to changing requirements.
- Conduct Thorough Testing: Regularly test for performance, usability, and security to maintain high-quality standards.
- Document Everything: Comprehensive documentation aids future development and troubleshooting.
