Structured 5-Stage Mobile Pipeline

From initial workflow sketch to live Play Store download in predictable, milestone-driven sprints.

1. Discovery & Scope

We map your business workflows, define user journeys, and document the complete functional specification before writing code. This eliminates scope creep and unexpected costs.

2. Wireframes & Prototype

Intuitive wireframes followed by clickable interactive prototypes — so your stakeholders touch and approve the exact user experience before development begins.

3. Sprint Build & QA

Agile 2-week sprints with continuous testing across real physical Android and iOS devices. You review working builds on staging at every milestone.

4. Store Deployment

Production keystore signing, 64-bit app bundle packaging, store graphics, privacy disclosures, and end-to-end Play Store and App Store submission.

5. Support & Evolution

Post-launch warranty monitoring, zero-crash monitoring, Android/iOS OS update compatibility, and continuous feature expansion as your active users grow.

Why Cross-Platform?

React Native & Flutter provide 100% native compiled execution on both platforms from one codebase — halving development costs and keeping features perfectly synchronized.

Frequently Asked Questions

Do you build for both Android and iOS?

Yes. By utilizing modern cross-platform engineering (Flutter and React Native), your app launches simultaneously on both platforms, saving 40–50% in development investment.

How much does custom mobile app development cost?

Our complete dual-platform packages start from ₹1,00,000 including complete UI/UX, database architecture, API endpoints, testing, and Google Play Store deployment.

Do you manage Google Play Store and Apple App Store compliance?

Yes. We handle package generation, cryptographic signing, store metadata, screenshots, data safety questionnaires, and compliance reviews until your app is live.

Can the mobile app connect to our existing database or software?

Yes. We integrate seamlessly with any existing ERP, CRM, SAP, Tally, or custom MySQL/PostgreSQL backends through secure REST or GraphQL APIs.
