Questions & Answers
Frequently Asked Questions
Clear answers to the questions clients ask before partnering with BrainTech Info Solutions in Lucknow.
How much does mobile app development cost in Lucknow?▼
Mobile app development costs vary based on functionality and backend requirements. A standard cross-platform MVP (Android & iOS) typically costs between ₹80,000 to ₹2,50,000. Feature-rich platforms with real-time tracking, payment gateways, and custom backend APIs range from ₹2,50,000 to ₹7,00,000+. We provide fixed-price milestone roadmaps.
Should I build a native app or cross-platform (Flutter / React Native)?▼
For 95% of commercial applications, modern cross-platform frameworks like Flutter or React Native are the optimal choice. They deliver 60 FPS performance, identical native look-and-feel, and reduce development and maintenance costs by 40-50% since one codebase powers both Android and iOS.
Do you publish our app to the Google Play Store and Apple App Store?▼
Yes. BrainTech manages the entire deployment process, including developer console configuration, privacy policy compliance, screenshot generation, and addressing any reviewer feedback until your app is publicly approved.
Can our mobile app work without an active internet connection?▼
Yes. We engineer offline-first data caching using SQLite or Hive. Users can view saved information and perform offline actions, which automatically synchronize with the cloud once an active internet connection is restored.
How do you handle mobile app updates after launch?▼
We structure apps to support over-the-air (OTA) updates where possible, alongside regular App Store and Play Store update releases. We offer ongoing maintenance contracts to ensure compatibility with new Android and iOS versions.
