Frequently Asked Questions

Should I build a native or cross-platform app?
For most startups and businesses, cross-platform (Flutter) is the best choice — single codebase, 50% cost savings, and near-native performance. I recommend native Kotlin/Swift only when you need platform-specific features like AR, complex animations, or deep OS integration.
How much does mobile app development cost in India?
A simple MVP starts at INR 25K-50K, medium complexity apps cost INR 60K-1.5L, and complex enterprise apps range from INR 1.5L-5L+. India offers significant cost savings compared to US/UK rates while maintaining high quality.
Do you handle app store submission?
Yes, I handle the entire process — building release versions, creating store listings with optimized metadata and screenshots, submitting for review, and resolving any rejection issues.
