Overview

Both platforms, half the cost

We build cross-platform apps with React Native or Flutter one codebase that ships to both iOS and Android, looks and feels native, and costs far less to build and maintain than two separate apps.

Why this approach

Custom-built vs the alternative

Same job, two very different outcomes.

Recommended

Custom-built with Exarth

One codebase that ships native-feeling apps to both stores, faster and cheaper.

Alternative

Two separate native builds

Two separate codebases, two teams, double the cost and the timeline.

  • CostOne codebase to build
  • Time to marketBoth stores sooner
  • Native feelNative-feeling on both
  • MaintenanceFix once, ship both
  • ConsistencyIdentical across platforms

For most apps, one cross-platform build delivers both stores at roughly half the cost without giving up the native feel.

The challenge

Patients were bouncing between booking, consults, pharmacy, and records. The team needed one polished app on both stores without maintaining two native codebases.

  • Designed a unified care journey for patients
  • Built once with Flutter for iOS and Android
  • Secure consults, payments, and records in one app
