👋 Hi there! I'm here to help. Ask me anything about our app development process, or select a question below.

The timeline depends on the complexity of your project. A simple MVP can take 6-8 weeks, while a feature-rich app with custom backend, third-party integrations, and advanced UI/UX typically takes 3-6 months. We work with you to define milestones and deliver iteratively, so you can see progress every step of the way.

Costs vary based on features, platform (iOS, Android, or both), design complexity, and backend requirements. A basic MVP starts around $15,000–$25,000, while a full-featured app can range from $30,000–$100,000+. We provide transparent quotes after a discovery call to understand your specific needs.

We develop for iOS, Android, and cross-platform using React Native and Flutter. We also build web apps with Laravel, React, and modern frontend frameworks. Whether you need a native experience or a single codebase for both platforms, we have the expertise to deliver.

Our tech stack includes Swift and Kotlin for native development, Flutter and React Native for cross-platform, Laravel and Node.js for backend, and AWS/Google Cloud for hosting. We also work with Firebase, Stripe, and other modern APIs to power your app.

We follow a 7-stage process: Discovery, Research, Wireframing, UI/UX Design, Development, Testing, and Launch. We work in agile sprints, providing regular updates, demos, and feedback loops to ensure your app is built exactly to your vision.

Yes! We provide lifetime maintenance & support for all projects. This includes bug fixes, performance monitoring, security updates, and feature enhancements. We stay with you long after launch to ensure your app continues to perform and evolve.
