Our Process

Discovery

We listen. Market research, user interviews, competitor analysis, and technical feasibility assessment. Strategy before code.

Prototype

Interactive wireframes and design systems. We validate ideas with users and stakeholders before writing production code.

Build & Test

Agile sprints, continuous integration, automated testing. Transparent progress, regular demos, and rapid iteration based on feedback.

Launch & Grow

App Store submission, beta testing, launch day support. Then analytics, user feedback loops, and feature roadmaps for sustained growth.

FAQs

How long does app development take? +

Timeline depends on complexity and scope. A simple MVP: 8–12 weeks. A feature-rich production app: 4–6 months. We work in 2-week sprints so you see progress every fortnight and can adjust course based on real user feedback.

Should we build iOS, Android, or both? +

iOS + Android is ideal for maximum reach. If budget-constrained, iOS typically has higher engagement and monetization. Android reaches more users. We recommend a phased approach: launch iOS first, then Android with cross-platform tools like React Native or Flutter.

Do you handle post-launch support and maintenance? +

Absolutely. We offer retainer-based support covering bug fixes, OS updates, performance optimization, and new feature development. Think of us as your long-term app partner, not just a dev shop.

What stack do you use? +

We specialize in React Native, Flutter, Swift, Kotlin, TypeScript, Node.js, Firebase, GraphQL, and AWS. We choose tech based on your requirements: native for peak performance, cross-platform for speed and cost, and progressive web apps for browser-first experiences.

How do you ensure app quality? +

Code reviews, unit tests, integration tests, E2E testing, and staged rollouts. We use CI/CD pipelines to catch bugs early. Beta testing with real users before App Store / Play Store launch. Continuous monitoring post-launch for crashes and performance.
