What does a mobile app developer do?
Mobile work has its own problems: flaky networks, small screens, battery use and app store releases. A good mobile engineer plans for all of them. Tell us your platform and we load the matching task.
Which mobile app skills do we test?
The skill matrix for a mobile app role starts with these six areas. You can change the weights in the role builder.
Platform choice
Native Swift or Kotlin, or Flutter and React Native, matched to your app.
UI and navigation
Screens that handle rotation, small devices and back navigation.
Offline and sync
Local storage, retry queues and conflict handling.
Performance
Smooth lists, image loading and memory use.
Release process
Builds, signing, store reviews and staged rollouts.
Testing
Unit tests for logic and UI tests for the main flow.
Which screening questions work for mobile app roles?
Screening questions go out by email right after a candidate enters the pipeline. Answers are scored against the skill matrix, with a written reason. Here are three from the mobile app library.
- Q1 How does your app behave when the network drops in the middle of a save?
- Q2 Tell us about an app store rejection or a crash you fixed after release.
- Q3 Native or cross-platform for a new app, and what decides it for you?
What does the mobile app coding task look like?
Offline notes screen. Build a notes list that works offline, queues edits and syncs when the connection returns. Time limit 90 minutes.
- Store notes locally and show them instantly
- Queue edits made offline
- Sync on reconnect and show a conflict message
- Test the sync logic without a device
suspend fun sync() {
if (!network.isOnline()) return
pending.all().forEach { edit ->
runCatching { api.save(edit) }.onSuccess { pending.remove(edit.id) }
}

The test and the AI interview look for different signals at each level. Use these to set the seniority in the role builder.
| Level | What you should see |
|---|---|
| Junior | Builds screens from designs and fixes simple crashes. |
| Mid | Owns features with offline handling and store releases. |
| Senior | Shapes app architecture, release strategy and performance budgets. |
How much does a mobile app developer cost?
Pay varies a lot by country, city, seniority and company. Public salary surveys show broad yearly ranges like these for mid-level to senior mobile app developers. Treat them as a starting point and check current surveys for your market.
Native specialists with years of store releases behind them usually earn more than developers who only build simple screens.
| Region | Typical range |
|---|---|
| United States | about 100,000 to 170,000 USD |
| Western Europe | about 50,000 to 90,000 EUR |
| Latin America and Eastern Europe, remote | about 35,000 to 75,000 USD |
| India | about 12,000 to 40,000 USD |

How does the mobile app shortlist work?
Mobile developers often have published apps. A public app plus public code gives a clear picture of what they ship. Every candidate then goes through the same screen, the mobile app task and an AI interview about their own solution. Integrity signals show paste events, similarity and AI code likelihood.
The top five land on your shortlist with a scorecard each. Your team meets them and makes the offer. You keep the hire and pay a flat subscription, from $99 per month billed yearly, not an agency fee.
