FAQ
How long does it take to build a mobile app?
Timelines vary based on complexity: Simple MVP (Minimum Viable Product): 4 to 6 weeks. Standard Business/E-commerce App: 8 to 12 weeks. Complex/Custom Enterprise Platform: 12+ weeks. We provide a detailed timeline breakdown during our discovery phase.
What does your 3-month free maintenance period include?
Our free support period starts the day your app is live on the App Store and Google Play. It covers critical bug fixes, performance optimizations, OS compatibility updates, and resolving any unexpected technical crashes. It does not cover building entirely new features.
Will you assist with publishing the app to the App Store and Google Play Store?
Yes, we handle the entire deployment process. We guide you through setting up your developer accounts (Apple and Google) and ensure your app complies with all guidelines to minimize the risk of rejection.
Do I own the source code and intellectual property (IP) of my app?
Yes, 100%. Once full payment is completed, you own all the source code, design assets, and intellectual property rights. We will hand over the repository access (e.g., GitHub or GitLab) to you at launch.
What is the difference between Native and Cross-Platform (Flutter) development?
Native (Swift for iOS / Kotlin for Android): Built specifically for one platform. Best for high-performance apps, heavy graphic processing, or deeply customized device-feature integrations. Cross-Platform (Flutter): One codebase powers both iOS and Android apps. This is highly efficient, faster .
Can you integrate advanced AI capabilities into my app?
Absolutely. We can integrate APIs from OpenAI (ChatGPT), Anthropic (Claude), Google Gemini, or custom Vision AI models. This allows your app to feature smart chatbots, automated data processing, image recognition, voice commands, and personalized AI recommendations.
