Start from a brief

Paste something like this.

“We're building a consumer fitness-tracking app for iOS and Android — users log workouts, track progress and share achievements with friends. Cross-platform with React Native, a Node/Firebase backend, push notifications and Apple/Google sign-in. Team is two mobile devs, one backend dev, a designer and a part-time QA. We want to be live in both app stores in about five months.”

That’s the before. Here’s the plan Ganttastic builds from it.

The mobile app development plan.

An editable mobile app development Gantt plan generated in Ganttastic, with task bars, dependencies, and milestones
  1. 1

    Discovery & Product Definition

    • Define target users, core use cases and the MVP feature list
    • Choose native (Swift/Kotlin) vs cross-platform (React Native/Flutter) and confirm the stack
    • Enrol in the Apple Developer Program and Google Play Console (allow time for org verification / D-U-N-S)
    • Draft monetisation, data-privacy and permissions requirements
    • Set up the repo, issue tracker and CI/CD pipeline (Fastlane / EAS / Bitrise)
  2. 2

    UX/UI Design

    • Map user flows and low-fidelity wireframes for the core journeys
    • Design high-fidelity screens and a reusable component / design system
    • Build an interactive prototype and run usability testing
    • Design the app icon, splash screen and store screenshots
    • Lock design sign-off and hand off specs to development
  3. 3

    Architecture & Backend Setup

    • Define the data model and API contract (REST or GraphQL)
    • Stand up the backend, database and authentication (OAuth, Sign in with Apple)
    • Configure push notifications (APNs and FCM)
    • Wire up analytics and crash reporting (e.g. Firebase Crashlytics)
    • Provision dev / staging / prod environments and secrets management
  4. 4

    App Development

    • Build the navigation shell, onboarding and authentication flows
    • Implement core feature screens with offline / local storage
    • Integrate backend APIs, push notifications and deep links
    • Handle platform specifics (runtime permissions, background tasks, iOS/Android UI)
    • Set up code signing, provisioning profiles and internal dev builds
  5. 5

    QA & Beta Testing

    • Write test cases and run functional and regression testing
    • Test across a real-device matrix (older iPhones, range of Android OEMs and OS versions)
    • Distribute beta builds via TestFlight and Play internal testing
    • Fix crashes, performance and accessibility issues
    • Verify analytics events, privacy labels and data-safety compliance
  6. 6

    Launch & Post-Launch

    • Prepare store listings, ASO keywords, screenshots and privacy nutrition labels
    • Submit to App Store review and Google Play, with a buffer for rejections
    • Run a staged / phased rollout and monitor release day
    • Track crash-free rate, store reviews and key activation funnels
    • Triage feedback and plan the first maintenance / point release

Key dependencies

  • Design sign-off gates development: engineers shouldn't build core screens until user flows and the component library are locked, or rework compounds across both platforms.
  • The backend API contract and authentication must be defined before the app team can integrate — mock or stub the API early so frontend and backend work can run in parallel.
  • Enrol in the Apple Developer Program and Google Play Console on day one; organisation verification (including Apple's D-U-N-S requirement) can take days to weeks, and without it you can't create provisioning profiles, TestFlight builds or store listings.
  • Code signing and beta distribution must be working before real-device QA, which in turn must finish before you can submit to the App Store and Google Play.

Timeline risks

  • The store gate is the most common slip: App Store review rejections over privacy labels, in-app-purchase rules or the guideline 4.3 'spam' clause can add days per resubmission, so submit a launch-ready build early and keep a review buffer.
  • Android device and OS fragmentation surfaces bugs late — start real-device testing during development, not after, and maintain an OEM/OS test matrix.
  • Unfinished backend endpoints, third-party SDKs and payment/auth integrations are frequent blockers; mock dependencies early and keep a scope-cut list so the MVP still ships on time.
