App Development

Most app projects do not fail at the first build. They fail at version two, when nobody planned for state, offline behaviour, migrations or release tooling. We plan for that in week one.

We build the client, the API and the deployment pipeline together, with crash reporting and feature flags in place before launch — so a bad release can be rolled back in minutes.

Key Features

One codebase, both stores

React Native and Flutter builds that feel native on each platform.

  • Platform-specific navigation patterns
  • Shared design tokens across web and app

APIs that hold up

Typed, documented, versioned endpoints with real rate limiting.

  • REST and WebSocket layers
  • OpenAPI docs for your team

Payments and auth

UPI, cards and wallets through PayU, plus OTP and social sign-in.

  • PCI-safe tokenised payments
  • Device-bound session security

Release engineering

CI builds, staged rollouts and over-the-air updates for JS layers.

  • Play Console and App Store Connect setup
  • Crash and ANR monitoring

How It Works

User stories, screen inventory and a release plan split into a shippable v1 and a backlog.

Data model, API contract, offline strategy and auth design, documented before build.

Screens built against the design system with real data from day one, reviewed weekly.

Payments, notifications, analytics, then load and security testing.

Submission, phased rollout, dashboards for crashes, retention and funnel drop-off.
