Mobile development is one of the few disciplines where you can point a recruiter directly to a live app on the App Store or Google Play - use that. A portfolio ties your published apps, code, and store metrics together in one place. Pair this with How to Build a Professional Portfolio and GitHub Portfolio Optimization.

What to Include

  • 2-4 published apps - App Store/Google Play links, screenshots, and a short description of your role on each
  • Store performance - downloads, ratings, or retention if you are allowed to share them
  • Code samples - GitHub repos showing architecture (MVVM, Clean Architecture), state management, and testing
  • Platform-specific skills - Swift/SwiftUI or Kotlin/Jetpack Compose, or cross-platform (Flutter, React Native) depending on your specialty
  • A demo video or GIF - a 15-30 second screen recording of key app flows for anyone who will not install the app

Frame Shipping, Not Just Code

Anyone can show a code sample - what stands out is evidence you can ship and maintain a real product. For each app:

  1. The problem it solves - one sentence on the user need
  2. Your specific contribution - especially if it was a team project (which features, which architecture decisions)
  3. What happened after launch - store rating, download milestones, a crash-rate improvement, or a performance fix you shipped

Where to Host It

  • GitHub for code, with clean READMEs and screenshots
  • A personal site via the TailorCV portfolio builder - to link store pages, demo videos, and code together
  • Direct links to your App Store and Google Play listings, not just screenshots of them

Keep Your Resume and Portfolio in Sync

Your resume, GitHub, and portfolio should tell the same story - same platforms, same architecture patterns, same headline apps - just at different levels of depth. Lock the resume down first with the ATS score checker and an ATS-friendly template, then mirror that positioning in your portfolio. See How to Add Your Portfolio Link to Your Resume for placing the link correctly.

Common Mistakes

  • Screenshots with no live link or demo video - reviewers rarely install unfamiliar apps
  • Listing "built an app" with no mention of your specific role on a team project
  • Outdated apps pulled from the store with dead links still in your portfolio
  • No testing evidence - unit or UI tests are increasingly expected, even for small apps

Pro Tips

  • Record a short screen capture for every app - it removes the friction of installing to evaluate your work
  • Include one app that handles a hard technical problem (offline sync, background processing, complex animations)
  • Generate your portfolio shell from your resume with the portfolio builder and embed your demo videos and store links

Frequently Asked Questions

My best work is a private company app I cannot show publicly - what do I do?

Describe the problem, your role, and the architecture without sharing proprietary code, and build one public side project to demonstrate hands-on skill. See Portfolio No Projects.

Should I show native or cross-platform work?

Show whatever matches your target roles. If you know both, lead with your strongest platform and mention the other as a secondary skill.

How do I align my resume?

Keep platform names, architecture patterns, and app names consistent across resume and portfolio.

Make This Practical

If this topic connects to your work samples, turn the advice into a live proof page with the TailorCV portfolio builder. After publishing, add the link correctly using How to Add Your Portfolio Link to Your Resume, tighten the page with the Portfolio Checklist Before Applying, and make sure recruiters can contact you through a clean Portfolio Contact Section.

Your portfolio works best when it supports the resume, not when it replaces it. Run the resume through the free ATS score checker, choose an ATS-friendly resume template, and use Portfolio SEO: Get Found so your name, platform, and strongest apps are easier to discover.
