❓ Common Questions

Frequently Asked Questions

Transparent answers on pricing, timelines, IP ownership, and technical SLAs. No ambiguity.

Flutter vs React Native — which should I choose?
Flutter is unmatched for rich brand-focused custom UI, smooth animations, and pixel-perfect parity on iOS and Android. React Native is ideal if you have an existing React web team or need deep code sharing with a web platform. We provide objective guidance based on your product roadmap and team structure.
How much does a mobile app cost in India?
A standard Flutter MVP app typically costs ₹3L–₹8L. Complex apps with real-time video, AI features, or fintech compliance range from ₹10L–₹25L. We provide a transparent milestone-based quote within 24 hours.
How long does mobile app development take?
A production-ready MVP is delivered in 6–10 weeks. Enterprise mobile platforms with advanced integrations generally span 12–16 weeks in phased deliveries with working demos every 2 weeks.
Do you handle the App Store and Google Play submission?
Yes. We manage all developer accounts, provisioning profiles, privacy declarations, screenshot generation, keyword targeting, and policy compliance for a guaranteed first-time store approval.
