How to write it
Link the apps. This is the whole advantage
A reviewer can download your work in thirty seconds, and if the resume gives them a way to do it, they will. Name the apps, put a store link in the header, and give the install scale and rating where they're good.
If everything you've built is internal, enterprise or under NDA, say so briefly and substitute scale — "internal field app used by 3,000 technicians daily" is perfectly strong. What doesn't work is describing mobile work in the abstract when the medium has a public shop window.
The metrics mobile hands you for free
Every mobile team already watches a set of numbers that make excellent resume bullets, and most candidates never quote them. Crash-free session rate is the headline: it's the clearest quality signal in the discipline and moving it from 99.1% to 99.94% represents real engineering.
Startup time, app size, ANR rate, store rating and review sentiment are all similarly available. Even review text is usable — "resolved the top App Store complaint; 1-star reviews fell 38%" connects engineering to the customer in a way few bullets manage.
- Installs, monthly active users, or daily sessions
- Crash-free rate or ANR rate, before and after
- Cold start time and app binary size
- Store rating, and any movement you caused
- Rollout mechanics: phased releases, beta cohort size
Native or cross-platform — pick a lane in the summary
iOS, Android and React Native postings are screened by different people looking for different words. A resume that claims all three equally reads as shallow in each, so lead with your genuine strength and list the others as secondary competence.
"Swift and SwiftUI, with production Kotlin" is credible. "iOS, Android, Flutter, React Native" invites the assumption that you've built one small thing in each. If you truly are a cross-platform specialist, say that plainly — it's a real specialism with its own demand.
Release management is undervalued signal
Shipping mobile software means dealing with store review, phased rollouts, forced upgrades, and the fact that you cannot hotfix a bad release the way you can on the web. Anyone who has owned that has learned things a web developer hasn't.
Mention the mechanics: TestFlight or Play Console beta cohorts, staged rollouts, a rejection you resolved, a kill switch you built. It tells a hiring manager you can be trusted with the release, not just the code.
Migrations show currency
Mobile platforms churn faster than most, and having done a real migration — UIKit to SwiftUI, Java to Kotlin, XML layouts to Compose — proves you're current rather than maintaining something from 2018.
The persuasive detail is how you did it: incrementally, screen by screen, without a rating drop. A big-bang rewrite that shipped is impressive; an incremental migration that never regressed the product is more impressive to anyone who has managed one.
