Native App Development Internship
Build the same product twice (once in Kotlin, once in Swift), and learn what actually differs between the platforms instead of guessing.

Two platforms, one product, no shortcuts
Cross-platform hides the differences. Native shows them. You will feel exactly where Android and iOS disagree about navigation, storage, permissions and lifecycle.
- 1You receive one product brief and one design file
- 2You build the Android version in Kotlin and Jetpack Compose
- 3You rebuild the same flows in Swift and SwiftUI
- 4You document the differences in a written comparison
iOS work is done on the team’s macOS machines. You do not need to own a Mac.
// Week 5: Room + coroutines, offline first class LedgerRepository( private val dao: LedgerDao, private val api: LedgerApi ) { fun observe(): Flow<List<Entry>> = dao.observeAll() suspend fun refresh(): Result<Unit> = runCatching { val remote = api.entries(page = 1) dao.upsertAll(remote.map { it.toEntity() }) }.onFailure { Log.w("Ledger", "sync failed", it) } }
Eight things you will actually be able to do
Kotlin and Swift
Two languages side by side: null safety, optionals, coroutines, async/await.
Compose and SwiftUI
Declarative UI on both platforms, and where their mental models diverge.
Architecture
MVVM, dependency injection, and keeping business logic off the UI layer.
Local storage
Room on Android, CoreData on iOS, and an offline-first sync strategy.
Networking
Retrofit and URLSession, typed models, error handling, retry and cancellation.
Navigation
Back stacks, deep links and the very different ways each platform handles them.
Permissions and lifecycle
Runtime permissions, background limits and process death on Android.
Store release
Signing, Play Console, App Store Connect, TestFlight and review guidelines.
The 12-week plan
Four phases. Each one ends in a deliverable that is reviewed and graded before the next opens.
Android first
Kotlin, Compose and a working Android app.
- Kotlin fundamentals, coroutines and flows
- Jetpack Compose layouts, state and theming
- Android Studio, Gradle and the build system
- Git branching and pull request review
A working Android app with three screens built from the supplied design file.
Data and architecture
Making the app survive bad networks and process death.
- MVVM, ViewModels and unidirectional state
- Retrofit networking with typed models
- Room database and offline-first sync
- Dependency injection with Hilt
An offline-capable Android app that syncs cleanly and restores state after being killed.
iOS counterpart
The same product, rebuilt the Apple way.
- Swift fundamentals, optionals and async/await
- SwiftUI views, state and navigation
- CoreData persistence and URLSession networking
- Xcode, schemes, simulators and provisioning
The same core flows running as a native iOS app, with a written note on every platform difference you hit.
Ship both
Testing, polish and two store-ready builds.
- Unit and UI tests on both platforms
- Accessibility, dark mode and dynamic type
- Signing, Play Console and App Store Connect
- Portfolio case study, CV rewrite, mock interview
A signed Android release and a TestFlight iOS build, plus a comparison write-up of both codebases.
Every intern ships the same app twice
You are given one brief and one design, and you deliver it natively on both platforms. Very few juniors can say that in an interview.
- A Kotlin Android app and a Swift iOS app
- Offline storage, networking and auth on both
- A written comparison that proves you understand each







What every Ezitech intern gets
Three things that make this different from a course you watch on a screen.
Live client briefs
You work on real Ezitech projects with real deadlines and real revision rounds, not recycled practice exercises.
A mentor, not a playlist
Weekly reviews with someone who does this work for a living, plus a team of interns around you to build with.
Portfolio and experience letter
You finish with shipped work you are allowed to show and a letter that says exactly what you delivered.
Verified certificate
Issued by Ezitech Institute and verifiable by employers.
Experience letter
On company letterhead, stating exactly what you delivered.
Two shipped builds
A native Android app and its iOS counterpart, both installable.
Interview preparation
CV rewrite, portfolio case study and a technical mock interview.
A route into the team
Top performers are considered first for paid junior roles.
Confidence in review
Twelve weeks of defending your own work to a senior practitioner.
Built for you if
- You are an undergraduate or fresh graduate in CS, IT or SE
- You know object-oriented programming in any language
- You want depth on one platform rather than breadth
- You are aiming at Android or iOS roles specifically
Not a fit if
- You want a certificate without doing the work
- You cannot give 25 hours a week for 12 weeks
- You are looking for a purely theoretical course
- You want to skip review and work alone
Questions people ask
Everything applicants email us about, answered before you apply.
Do I need to know Kotlin or Swift already?
How many hours a week does it take?
Is it remote or onsite?
I do not own a Mac. Can I still do the iOS half?
Can final-year students apply?
How do I apply?
Not sure Native App is the one?
Every app development internship runs three months, hybrid, with the same mentor model. Or take the six-month All-in-One flagship.
Flutter
One Dart codebase that ships to both Android and iOS.
View trackUI & UX
A product brief turned into wireframes, a prototype and a design system.
View trackAndroid
A Kotlin app with local storage, networking and a proper architecture.
View trackGame Dev
A playable 2D or 3D game in Unity with a store-ready build.
View trackLearn both platforms properly, not approximately
Three months, one shipped piece of real work, a mentor who reviews you every week. Registration takes five minutes.
