Discipline Specification // MOBILE APP DEVELOPMENT

Mobile App Development for iOS & Android

A high-performing mobile app isn't a web wrapper. It requires 60fps gesture physics, instant cold starts, native hardware integrations (camera, biometrics, secure storage), offline-first data sync, and a release pipeline that navigates Apple and Google app store review guidelines without friction. SynS Infrastructure engineers cross-platform mobile apps using React Native and Expo — delivering single-codebase velocity with native performance on both iPhone and Android.

Target Alignment

Who this is for

  • 01A founder with a validated product who needs an iOS and Android app live on the App Store and Google Play Store in weeks.
  • 02A SaaS platform or web product expanding to native mobile to enable push notifications, background sync, and App Store distribution.
  • 03A business owner looking for an engineering partner to design, build, test, and shepherd a mobile app through store reviews to live production.
Deliverable Scope

What's included

  • ✓Cross-platform architecture (React Native / Expo) sharing up to 95% of business logic across iOS and Android
  • ✓Native device integration: biometric auth (FaceID / TouchID), camera, geolocation, and secure keychain storage
  • ✓Offline-first state synchronization with resilient local SQLite / MMKV storage and automatic conflict resolution
  • ✓Automated push notification infrastructure via APNs and Firebase Cloud Messaging (FCM)
  • ✓TestFlight (iOS) and Google Play Internal Testing distribution for private stakeholder testing before launch
  • ✓End-to-end App Store and Google Play submission handling, compliance checks, and rejection mitigation
  • ✓Sentry crash monitoring, performance tracing, and over-the-air (OTA) instant update support

01

Scope & Architecture

Define exactly what gets built, what doesn't, and milestone criteria — in writing, before work starts.

02

Iterative Staging

Weekly written updates with staging deployments from the first sprint. Test features as they are built.

03

Handover & Ownership

100% repository, credentials, and documentation handed over. Retainers available for ongoing evolution.

Technical Clarifications

Questions & answers for this discipline.

Will the app be published on both Apple App Store and Google Play Store?+

Yes. We configure certificates, provision profiles, generate application bundles, and manage the full submission process for both Apple App Store Connect and Google Play Console until your app is live and downloadable.

How long does mobile app development typically take?+

A focused MVP or companion app typically ships in 2 to 4 weeks. Full-scale platforms with custom native hardware integrations take 4 to 8 weeks.

Can the mobile app share the same database and user accounts as our web app?+

Absolutely. We engineer unified API backends (PostgreSQL/Supabase/REST) so user accounts, billing, data, and permissions sync seamlessly between web and mobile devices in real time.

Do you handle App Store review guidelines and potential rejections?+

Yes. Apple and Google have strict privacy and metadata guidelines. We ensure compliance with App Store Review Guidelines (including Apple Login requirements and privacy manifests) and resolve any reviewer questions directly.
