What technologies do you use for mobile and web app development?

We build modern, high-performance applications using React Native and Flutter for iOS & Android mobile apps, Next.js and React for web applications, Node.js and Python for backend APIs, and PostgreSQL/MongoDB for databases hosted on AWS or Vercel infrastructure.

How long does it take to build a custom mobile app in Sydney?

Rapid MVPs can be built and deployed in as little as 3 to 7 days. Full-featured custom iOS & Android applications typically take 3 to 8 weeks depending on backend API integrations, UI complexity, and testing requirements.

Do I own 100% of the code and intellectual property (IP)?

Yes, absolutely! Upon completion of your project, 100% of the source code, IP rights, Figma designs, database schemas, and cloud deployment keys belong entirely to your business.

Can Lociax Software help submit my app to Apple App Store & Google Play?

Yes. We manage the end-to-end App Store Optimization (ASO) and deployment process, including Apple Developer account configuration, Google Play Console setup, privacy policies, and app approval workflows.
