The most common mistake in a mobile app developer CV is treating iOS and Android experience as equally valuable to list. Companies do not hire "mobile app developers" — they hire iOS developers, Android developers, or React Native developers. A CV that claims all three at equivalent skill levels reads as someone who is mediocre at each, rather than expert in one. The second mistake is closely related: describing what apps do rather than how many people use them. Mobile developers have access to objective quality evidence — App Store ratings, download numbers, crash rates, daily active users — that almost no other engineering discipline can provide with the same precision. This guide covers how to specialise a mobile app developer CV correctly, the ATS keywords that surface it in platform-specific searches, and how to write bullets that use real user metrics to prove production quality.
What Mobile App Developer Job Descriptions Actually Hire For in 2026
Companies rarely post a generic "mobile app developer" role. The JD will specify one of three archetypes, and your CV needs to match it clearly:
iOS Developer — Swift and SwiftUI are now the expected standard; Objective-C is legacy. JDs expect: UIKit familiarity for existing codebases, SwiftUI for new work, HealthKit/MapKit/ARKit integration experience for specialised roles, Core Data or Swift Data for persistence, and familiarity with the App Store review process and TestFlight. Xcode proficiency is assumed.
Android Developer — Kotlin is the standard; Java is legacy. JDs expect: Jetpack Compose for modern UI, MVVM with LiveData/StateFlow, Retrofit for networking, Room for local persistence, Firebase (Crashlytics, Analytics, FCM) integration, and Play Store submission experience. Android Studio proficiency assumed.
React Native / Flutter Developer — Cross-platform roles typically require TypeScript knowledge for React Native or Dart for Flutter. JDs expect: native module bridging experience (for React Native), platform-specific behaviour handling, over-the-air update tools (CodePush, EAS Update), and the ability to navigate platform-specific bugs without escalating to a native developer.
Mobile app developer salaries in 2026: £40K–£70K UK mid-level; $90K–$155K US, with senior iOS and Android developers at larger companies reaching $170K base. App Store experience and shipped apps with real users consistently push candidates into higher salary brackets at interview.
ATS Keywords for a Mobile App Developer CV
Platform-specific ATS filters are stricter in mobile than in most other engineering disciplines. An ATS system filtering for "iOS developer" will not reliably surface a CV that says only "Mobile App Developer." Specificity in the headline and Skills section is not optional.
Essential ATS terms by platform:
- iOS titles: iOS Developer, Swift Developer, SwiftUI Developer, iOS Engineer, iPhone Developer
- Android titles: Android Developer, Kotlin Developer, Jetpack Compose Developer, Android Engineer
- Cross-platform titles: React Native Developer, Flutter Developer, Mobile Engineer, Cross-Platform Developer
- iOS technologies: Swift, SwiftUI, UIKit, Core Data, HealthKit, Xcode, TestFlight, CocoaPods, SPM, MVVM, Combine
- Android technologies: Kotlin, Jetpack Compose, Android SDK, Room, Retrofit, Hilt/Dagger, Firebase, Gradle, MVVM, Coroutines
- Cross-platform: React Native, Flutter, Dart, Expo, TypeScript, Firebase, CodePush, Fastlane
- Long-tail phrases: mobile app developer resume examples, how to write a mobile app developer resume, iOS developer resume, Android developer resume, mobile developer skills for resume
Headline rule: Specialise your title immediately. "Mobile App Developer | iOS · Swift · SwiftUI" or "Mobile App Developer | React Native · TypeScript · Firebase" narrows the ATS match and the recruiter's mental model in one line. List your platform-specific technologies before any cross-platform ones.
CV Structure and Bullets That Prove Production Quality
Section order for a mobile app developer CV:
- Headline — title + platform specialisation + primary tech stack
- Skills — split by category: Platform / Languages / Architecture / Tools / Testing
- Experience — 4–6 bullets per role; App Store metrics belong here
- Projects / Shipped Apps — list with App Store/Play Store links, downloads, and ratings
- Education — bottom of page for experienced developers
Two pages for 3+ years; one page for under 2. App Store and Play Store links in the Projects section serve the same function as a portfolio for a web developer — they are objective evidence of production capability. Interviewers check them.
The three data points that make a mobile developer bullet stand out: what you built, how many users it reached, and what quality evidence you have (crash rate, rating, performance metric). Three examples:
- Architected and shipped a fitness tracking iOS app in Swift and SwiftUI — 47,000 downloads in 6 months, integrated HealthKit for passive data sync, implemented offline Core Data persistence, and maintained a 4.8-star App Store rating across 3 iOS version migrations
- Rebuilt the company's React Native app from class components to functional components with TypeScript, reducing bundle size by 34% and cutting the crash rate from 2.1% to 0.3% across Android and iOS over 8 months
- Led performance optimisation of the main feed in an iOS news application — improved average scroll frame rate from 45fps to consistent 60fps through async image loading, UICollectionView diffable data sources, and background data pre-fetching
Mobile developer technical interviews cover platform-specific patterns (Swift concurrency, Kotlin Coroutines, React Native bridging), architecture discussions (MVVM vs. MVI vs. Clean Architecture — why, not just what), and sometimes algorithmic coding in the platform's primary language. Your CV shapes which depth of architecture question you receive.
Three Mobile App Developer CV Mistakes That Cost You Interviews
Listing both iOS and Android skills at equal weight. A Skills section showing Swift, Kotlin, React Native, Flutter, Objective-C, and Java at equivalent prominence does not signal versatility — it signals that you have touched everything and committed to nothing. Recruiters hiring for an iOS role will move to a candidate whose CV leads with Swift and SwiftUI. The fix: lead firmly with your primary platform. If you genuinely work cross-platform in React Native, say that — but as a platform choice, not as a hedge against not being specialized.
No shipped app metrics anywhere. App Store downloads, Play Store ratings, daily active users, and crash rates are data points that only mobile developers have access to — and almost no mobile developer CV includes them. "Built a travel planning app" is what 200 other candidates say. "Travel planning app — 31K downloads, 4.7-star rating, 0.4% crash rate, featured in the UK App Store's 'Trip Planning' category in March 2025" is what gets you a call. Include at least one set of real metrics somewhere in your experience or projects section.
Describing architecture patterns without explaining the choice. "Built the app using MVVM architecture" appears in many mobile developer CVs at mid-level. Senior interviews probe why — why MVVM over MVC, why Combine over Notifications, why chose Room over SharedPreferences. A bullet that says "Migrated the Android codebase from MVC to MVVM with Kotlin Coroutines, enabling testable ViewModel logic and reducing the unit test coverage from 12% to 67% over 4 months" demonstrates architectural reasoning. The pattern name alone does not.
