What is your Development Methodology for both ideas/existing platforms?

Our standard approach is to keep our services as open-ended as possible for our clients. Hence, platforms developed from scratch or upgrade an owned app/website with existing systems are all offered. (1) Agile Development Methodology, including scrum, crystal, extreme programming (XP), and feature-driven development (FDD). The main objective is to minimize risk (such as bugs, cost overruns, and changing requirements) when adding new functionality, which allows users to realize software benefits earlier, with frequent incremental improvements. (2) Waterfall Development Methodology, consisting of sequential phases (requirements, design, implementation, verification, maintenance) focusing on distinct goals, which makes it easy to understand and manage and is suitable for projects with clear objectives and stable requirements.

Your main Engagement Model for development projects?

We offer 2 cooperation models for companies: (1) Offshore Development Centre (ODC) and (2) Project-based contract, depending on specific requirements of each project. Find out more terms of each model at: https://sotatek-test.sotatek.works/technologies/

What Our Customers Say

View all

We were looking for an offshore company partner and finally we found SotaTek and had started working with them since September 2022. ( ... ) They helped us pay down the technical debt and also accelerate our development. Without SotaTek, we wouldn't be able to actually handle so many technical initiatives. Thanks to SotaTek, we were able to deliver all of them in time. So if you are looking for an offshore engineering team. I'd recommend SotaTek.

Lemon Healthcare aims to extend its presence beyond South Korea into Southeast Asia. For that reason, we decided to choose SotaTek.

Through this, we intend to localize and expand smart hospital ERP in Southeast Asia and help both companies grow.

Frequently Asked Questions

What is mobile application development services?

Mobile application development services encompass the end-to-end process of designing, building, testing, and maintaining mobile apps for iOS and Android platforms. These services include native and cross-platform development, UI/UX design, backend integration, security enhancements, and ongoing updates to ensure seamless performance and user engagement.

How much does a mobile app cost?

The cost of mobile app development varies depending on factors like the complexity of the app, the features required, and the platform. On average, a simple app can cost around $10,000 to $50,000, while complex applications with advanced features may range from $50,000 to $200,000 or more.

What is a service in app development?

In app development, a service refers to a background process that runs independently of the user interface, performing tasks such as data synchronization, push notifications, API communication, and background updates. Services ensure smooth app functionality by handling operations that do not require direct user interaction, improving performance and efficiency.

How do you ensure the security of an application?

Ensuring the security of an application involves implementing multiple layers of protection throughout development and deployment. Key practices include:

Secure Coding Practices – Following industry standards like OWASP to prevent vulnerabilities such as SQL injection, XSS, and CSRF.
Data Encryption – Encrypting sensitive data both at rest and in transit using protocols like AES and TLS.
Authentication & Authorization – Implementing strong authentication (e.g., multi-factor authentication) and role-based access control (RBAC).
Regular Security Testing – Conducting penetration testing, vulnerability assessments, and code audits.
Secure API Communication – Using token-based authentication (OAuth, JWT) and HTTPS for secure data exchange.
Continuous Monitoring & Updates – Keeping the application updated with security patches and monitoring for threats in real time.

By combining these strategies, applications can minimize security risks and protect user data effectively.

How can I choose a mobile application development company?

When choosing a mobile app development company, look for their experience, portfolio, client reviews, and the technologies they use. It's also crucial to check whether they offer post-launch support and maintenance services to ensure the app runs smoothly after deployment.
