Mobile App Development (iOS & Android)

Home / Projects / Mobile App Development (iOS & Android)

Overview

Production-grade mobile app development for iOS and Android — consumer apps (health, wellness, fitness, content, marketplace), B2B apps (field service, dispatch, inspection, inventory), and embedded mobile front-ends for SaaS platforms. We ship cross-platform (React Native or Flutter) so a single codebase covers both stores without compromising on native feel: real navigation transitions, real haptics, native camera and biometrics, real push notifications, and platform-correct UI patterns. As a reference for the kind of polished cross-platform consumer app we build, see Nobu Mental Wellness & Therapy on the App Store and Google Play — daily check-ins, AI conversational coaching, mood/journal tracking, guided meditations, and a tight progress-tracking loop, all shipped to both platforms with consistent UX.

The Challenge

Mobile is unforgiving. App Store review can reject you for a missing privacy disclosure, a metadata mismatch, or a third-party SDK that's been deprecated. Google Play Console enforces target-API and data-safety updates that force re-submission. iOS and Android diverge on permissions, background tasks, notification handling, in-app purchase rules, and deep-linking. A crash on launch tanks your rating in 48 hours. Build pipelines (Xcode + Fastlane + EAS or Codemagic) have to be reliable enough that any engineer on the team can ship a release without 'works on my Mac' surprises. And the analytics + crash reporting have to be wired in from day one — not retrofit after the first bad release.

Our Approach

We pick the cross-platform stack on the actual project profile (React Native + Expo when iteration speed and OTA updates matter; Flutter when custom rendering and tight animations dominate; native when there's a hard reason). We build a clean architecture layer (TypeScript or Dart) with shared business logic, platform-specific UI affordances where it matters, and native modules for camera/biometrics/secure storage/notifications. CI/CD ships via Fastlane (iOS) and Gradle (Android) with EAS Build or Codemagic; releases go to TestFlight and Play Internal Testing on every merge to main, and to production on tagged releases. Sentry handles crashes; Mixpanel/Amplitude/PostHog handles product analytics; OneSignal or Firebase handles push. App Store and Play Store listing assets, screenshots, privacy disclosures, and ASO are part of delivery — not an afterthought. We ship the first public release with the App Store and Play Store review checklist already cleared.

Key Features

  • Single codebase ships to App Store and Google Play
  • Native camera, biometrics, secure storage, and push notifications
  • Deep linking and universal links wired in on both platforms
  • In-app purchases / subscriptions via StoreKit + Play Billing (RevenueCat)
  • Offline-first sync with conflict resolution where applicable
