Hire Mobile App Developers on Open Lance
Hire iOS, Android, and cross-platform developers who have shipped to the stores before. Post the job free, compare ranked proposals, and fund each milestone into escrow so you pay for a build that works on a real device, not a promise.
What mobile app developers deliver
What you can get with Mobile App Development
iOS and Android apps
Native Swift or Kotlin builds when performance, platform APIs, or offline behaviour genuinely matter.
Cross-platform in React Native or Flutter
One codebase for both stores, which usually halves the build and maintenance cost for standard product work.
App store submission
Signing, provisioning, screenshots, listings, and the review process — including getting a rejection overturned.
Backend and API integration
Auth, push notifications, payments, analytics, and syncing that behaves on a flaky mobile connection.
Existing app rescue
Take over an abandoned or crashing app, fix the crash rate, and get a release out again.
Releases and maintenance
OS upgrades, SDK deprecations, and store policy changes handled on a retainer so the app never goes stale.

Hiring guide
What to look for in a Mobile App Development freelancer
Mobile is unforgiving: a bad build gets rejected by a store, crashes on a device you do not own, or quietly breaks at the next OS release. These checks tell you whether someone has actually lived through that.
- Apps you can download today. Store links, not videos. Install one and use it — crash rate and polish are obvious within a minute on your own phone.
- They have shipped through review. Getting an app approved is its own skill. Ask what got rejected and how they fixed it; everyone experienced has a story.
- An honest native-versus-cross-platform answer. Someone who always recommends the same approach is selling their comfort zone rather than assessing your product.
- A device and OS matrix. Ask which devices and OS versions they will test on. "It works on my phone" is where most mobile disputes begin.
- Store accounts in your name. Your company should own the Apple and Google developer accounts. If the developer owns them, you cannot ship without them.
A good first milestone for mobile is a running build on a real device with one screen wired to real data — far more telling than a design file, and it proves the toolchain works before you fund the rest.

FAQ
Hiring mobile app developers: common questions
Should I build native or cross-platform?
Cross-platform, usually React Native or Flutter, covers most product apps at roughly half the build and maintenance cost because one codebase serves both stores. Go native when you depend on heavy graphics, tight hardware access, background processing, or platform features that arrive first on iOS or Android. A good developer will tell you which case you are in rather than defaulting to one.
How long does an app take to build?
A focused first version with a handful of screens and one integration is typically a few weeks; a product with accounts, payments, and sync is months. The honest answer depends on scope, so post the job with your must-have features and let proposals give you real ranges rather than an internet average.
Do I need separate developers for iOS and Android?
Not if you build cross-platform, which is why most teams start there. Native builds do usually mean two specialists, or one developer working sequentially. Either way, budget for both stores, because submission, review, and store assets are per-platform work even when the code is shared.
Who owns the app store accounts?
You should. Register the Apple Developer and Google Play accounts under your company and add the freelancer as a team member. This is the single most common handover problem in mobile work, and it is entirely avoidable by setting it up before the first release.
What happens when Apple or Google changes their rules?
Apps need periodic maintenance as operating systems, SDKs, and store policies change, whether or not you add features. Many clients keep their developer on a monthly retainer for exactly this, which Open Lance supports alongside fixed-price and hourly contracts.
