Frequently Asked Questions

Everything you need to know before we start. Still have questions? Just reach out — we're happy to help.

Every app is unique, but here's a realistic guide: A simple MVP starts around $8,000–$15,000. A mid-complexity app with API integrations and custom UI typically runs $15,000–$40,000. Enterprise-grade apps with AI features, real-time data, and advanced security range from $40,000+. We provide a detailed, itemized quote after your free consultation — no hidden fees, ever.
Typical timelines depend on the scope and features required. A standard MVP usually takes 6 to 10 weeks from discovery to app store launch, while more complex applications take 3 to 6 months. We maintain strict milestones with bi-weekly sprint demos so you always know where your project stands.
Yes, absolutely! We offer comprehensive post-launch maintenance packages that include bug fixing, OS update compatibility, server monitoring, performance tuning, and scaling new feature iterations as your user base grows.
You do. 100%. Upon final project delivery and full payment, all intellectual property rights, GitHub repositories, designs, and database configurations are completely transferred over to your ownership.
Cross-platform frameworks like React Native or Flutter are ideal for 90% of modern apps, offering near-native performance while saving 40-60% on development time and cost. Pure native development (Swift/Kotlin) is recommended for heavy 3D gaming, complex hardware integrations, or specialized OS-level features. We help you choose the right stack during consultation.
Yes! We specialize in integrating state-of-the-art AI capabilities—such as LLM chatbots, automated recommendations, computer vision, voice recognition, and predictive analytics—into both legacy systems and newly built applications.
