How We Work

Our Proven Process

A structured, transparent approach that keeps you informed at every step.

Discovery & Requirements

We start with a deep-dive call to understand your business goals, target audience, technical requirements, and desired outcomes. Every decision is data-backed, not guesswork.

Design & Prototyping

Our designers create wireframes and high-fidelity mockups for your approval before any code is written. You see exactly what you're getting before development starts.

Agile Development

Development runs in sprints with regular progress demos. You can track every milestone via our project portal and provide feedback continuously throughout development.

Testing & Quality Assurance

Every deliverable goes through rigorous testing — functional testing, cross-browser/device compatibility, performance benchmarking, and security checks before handover.

Deployment & Launch

We handle production deployment, DNS setup, SSL configuration, server hardening, and launch checklist verification. Zero-downtime deployments as standard.

Ongoing Support

Post-launch we offer maintenance packages, monitoring, backups, updates, and priority support. Our clients never feel abandoned after delivery.

Common questions

Android and iOS app development questions, answered

What clients ask before starting a mobile app build.

Talk to an engineer

A straightforward app with accounts and a handful of screens is a mid five-figure to low six-figure rupee build. Cost is driven by the number of distinct screens, whether you need offline support, payment integration, and how much backend has to be built behind it. A cross-platform build covering Android and iOS together is considerably cheaper than two native apps.

Cross-platform with React Native or Flutter for most business apps: one codebase reaches Android and iOS, which roughly halves build and maintenance cost with no difference a user would notice. Go native when the app leans hard on device hardware, needs sustained high frame rates, or ships platform features the day they launch.

Yes — Android and iOS, native or cross-platform. We also handle the parts teams forget to budget for: Play Store and App Store submission, store listings, signing keys, review responses and the update cadence after launch. Getting rejected by App Store review is a schedule risk, so we plan for it rather than discover it.

Eight to sixteen weeks for a first release, plus one to three weeks for store review and launch. An app is rarely finished at version one; we plan the first release around the smallest thing genuinely useful to your users and iterate from real usage rather than guessing at feature lists up front.

Yes. We publish under your developer accounts so the listings, the signing keys and the user reviews belong to you — never under ours. If you do not have accounts yet we walk you through creating them, because an app published under an agency account is an app you can lose access to.

Budget roughly fifteen to twenty percent of the build cost a year. That is not padding: Android and iOS ship breaking platform changes annually, certificates expire, and both stores drop apps that stop meeting current target-SDK requirements. An unmaintained app quietly stops being installable.

Usually. We start with an audit of the codebase, the build pipeline and the store accounts, and give you a written assessment of what is salvageable before quoting. The blocker is almost never the code — it is whether you can get the signing keys and store account access from whoever holds them. Chase that first.

You do. On final payment the source code, the database and the design files are yours, handed over in open formats with no licence attached to us. We do not hold your data hostage as a retention tactic, and our hosting is not a requirement — several clients run what we built on their own infrastructure with their own team.
