Mobile App Development

Mobile app costs depend on platform choice and feature scope. A simple cross-platform app (3–5 screens, basic auth, REST API) runs ₹4L–₹12L ($5k–$15k). A production-grade app with payments, push notifications, offline support, and a backend lands at ₹12L–₹40L ($15k–$50k). Complex apps — real-time chat, video, AI features, or marketplace logic — start at ₹40L ($50k) and can exceed ₹2Cr ($250k+). Native iOS/Android builds typically cost 1.4–1.8× the cross-platform equivalent because two codebases double the build and QA effort. App Store and Play Store submission, design system, and 30 days of post-launch support are included in our quotes by default.

Both are mature, both ship to iOS and Android from one codebase. Pick React Native if your team is already React/JavaScript/TypeScript-heavy, you want maximum library reuse with the web product, or you need deep native module integration (Bluetooth, complex camera flows, AR). Pick Flutter for highly custom UI, smooth animations, or when you want pixel-identical rendering across platforms — Flutter draws its own UI rather than mapping to native components. For most B2C and B2B apps we recommend React Native with Expo because it's faster to iterate and easier to hire for. For graphics-heavy or design-system-heavy apps, Flutter often wins. We're proficient in both.

Yes — submission is included in every project quote. We handle Apple Developer and Google Play Console account setup (or use yours), app metadata, screenshots, App Store Optimization (keywords, title, subtitle, descriptions), privacy policies, and the submission itself. We also handle initial review responses, common rejection reasons (privacy nutrition labels, sign-in with Apple, in-app purchase rules), and resubmission. First-time approval rate on our submissions is around 85% — when rejections happen, we fix and resubmit within 24–48 hours. Post-launch, we set up TestFlight (iOS) and Internal Testing (Android) for ongoing builds, configure crash reporting (Sentry, Firebase Crashlytics), and provide guidance on Play Store and App Store review optimization.

Realistic timelines: a simple cross-platform app (auth + 5 screens + basic API) ships in 6–10 weeks. A production app (15–25 screens, payments, push notifications, offline mode, multi-environment builds) takes 12–20 weeks. Complex apps with real-time features, video calling, marketplace logic, or AI integrations run 20–32 weeks. We work in two-week sprints with TestFlight/Internal Testing builds from sprint two, so you and your stakeholders see real builds on real devices throughout. App Store and Play Store submission adds 1–2 weeks (review queues vary). Most delays come from delayed content, late design feedback, or backend dependencies — we lock scope and content deadlines at kickoff to keep timelines honest.

Yes — we ship apps to global App Store and Play Store regions regularly. International work covers US, UK, UAE, Australia, Singapore, and EU clients. We handle regional concerns: payment integrations (Stripe, Apple Pay, Google Pay internationally; Razorpay, UPI for India), regional auth (Sign in with Apple required globally for App Store, Google Sign-In, social logins), localization (i18n for content and RTL support for Arabic/Hebrew), GDPR/CCPA compliance for data handling, and regional analytics. We sign NDAs and IP assignment agreements, and bill in USD or your local currency. Async-first communication with daily Slack updates and weekly Loom demos keeps stakeholders aligned regardless of time zone.

We build the full stack — frontend, backend, infrastructure — unless you have an existing backend you want us to integrate with. Default backend stack: Node.js + TypeScript + Postgres + Prisma + Redis on AWS, GCP, or Vercel. We design REST or GraphQL APIs, handle auth (JWT, OAuth, biometrics), file uploads (S3/R2), push notifications (FCM, APNS, OneSignal), and observability (Sentry, Datadog, or Grafana). Post-launch retainers cover OS updates (iOS and Android annually), dependency updates, App Store review responses, A/B tests, and new feature work. Retainers start at ₹60k/month. We also offer one-off engagements for specific feature additions if monthly retainers don't fit your model.

Cross-platform (React Native, Flutter) is the right default for most apps: 80–90% of UI is shared, faster to build, easier to maintain, and the performance gap with native has closed for typical product features. Go fully native when you need: heavy AR/VR/computer vision, deep camera or audio processing, watchOS/widgets/CarPlay/Wear OS, hardware integration (Bluetooth peripherals, IoT, NFC at the OS level), or AAA game-grade performance. Some teams ship cross-platform for the main app and native for specific extensions (Apple Watch app, Android Wear). We help you decide during discovery — there's no universally correct answer, just a trade-off between speed, cost, and the specific platform features you need.

Rejections happen — typically over privacy disclosures, sign-in with Apple compliance, in-app purchase rules, or metadata issues. When they occur, we read the reviewer's notes, fix the underlying issue, document the change, and resubmit within 24–48 hours. Most rejections clear on the second submission. For post-launch updates, we use a release-train model: bug fixes ship as patch releases (1.x.1, 1.x.2) on a 2-week cadence, features ship as minor releases monthly, and major releases (annual or biannual) bundle larger UX changes. Phased rollouts (1% → 10% → 50% → 100%) catch issues early. Crash-free user rate above 99.5% is our standard quality bar before any rollout.
