What they build
Most teams who hire an app developer want one of four things: a first version of a consumer app, an internal tool that replaces a clipboard or a spreadsheet, a mobile companion to a web product they already run, or a rescue on a codebase that a previous contractor left half finished. A senior mobile developer does more than write screens. They pick the architecture, decide what happens when the network drops, wire the backend, set up crash reporting and analytics, then carry the build through App Store and Google Play review without you touching a certificate.
Swift and SwiftUI builds targeting current iOS, with Core Data or SwiftData persistence, push notifications, StoreKit subscriptions and TestFlight distribution.
Kotlin with Jetpack Compose, Room, WorkManager for background jobs, Play Billing and a release pipeline into internal and production tracks.
One codebase across both stores, with native modules dropped in where the camera, Bluetooth or background location need real platform access.
Auth, sync, push infrastructure and REST or GraphQL endpoints on Firebase, Supabase or your own servers, sized for the traffic you actually expect.
Local-first data, conflict resolution and queued writes so the app keeps working in a basement, on a job site or on a plane.
Submissions, review rejections, privacy labels, signing and provisioning, plus taking over abandoned codebases and getting them shippable.
If the app is one half of a larger product, teams often pair a mobile engineer with a freelance web developer for the admin dashboard and marketing site, or a freelance product designer to get the screens right before a line of Swift gets written. When the plan is one JavaScript codebase across both stores, the same skills cover the web app, so you can hire React developers who ship React Native and the browser front end together.
Rates
Platform count is the biggest lever: two native codebases cost close to double one. After that it is hardware access, offline behavior and payments, in that order. Developers on SuperGig keep 100% of their rate, quote it up front, and work in milestones you fund through escrow for freelancers, so an unbuilt screen never becomes a paid deliverable.
| Specialty | Hourly rate | Typical work |
|---|---|---|
| iOS developer (Swift, SwiftUI) | $95 to 150/hr | Native iPhone and iPad apps, StoreKit, HealthKit, App Store submission |
| Android developer (Kotlin) | $90 to 145/hr | Jetpack Compose apps, Play Billing, background work, device fragmentation |
| React Native or Flutter developer | $80 to 135/hr | One codebase, both stores, native modules where the app needs them |
| Mobile backend and API engineer | $85 to 140/hr | Auth, sync, push, REST or GraphQL, Firebase or custom infrastructure |
Bands reflect US-based senior freelancers in 2026. Junior and mid-level developers quote below these ranges and usually need more direction. For the full picture across engineering roles, see our freelance developer rates guide and what it costs to hire a freelancer.
A useful rule for project budgets: a single-platform MVP with sign-in, five or six core screens and one integration lands around $18,000 to $45,000. Two native platforms with payments, offline sync and push runs $60,000 to $150,000. Those numbers assume one senior freelancer, not an agency bench, and they include store submission. Our pricing page shows exactly how the 10% project fee applies, and freelancer versus agency compares the two cost structures side by side.
Vetting
The screen is built to pass fewer than 1 in 20 applicants.
On bidding sites you sort hundreds of proposals yourself and the App Store screenshots in a profile prove very little. We do the screening first and send a short list. See how that differs from Upwork, Toptal and Fiverr, or read how to vet a freelancer if you would rather run the process yourself.
Briefing guide
iOS only, Android only, or both. If you are not sure, describe your users instead. A US consumer app usually starts on iOS, a field or logistics tool often starts on Android, and the developer can tell you which order saves money.
A rough screen list ("login, map, job detail, camera upload, history") is far easier to estimate than a paragraph of goals. Ten screens and a sketch beat a twenty page requirements document every time.
This one line changes the architecture and the price. Read-only cache is cheap. Full local-first sync with conflict resolution can add weeks. Decide before the first milestone, not during it.
In-app purchases, subscriptions, Stripe, third-party login and anything touching health or location data all carry store review rules. Naming them in the brief keeps a rejection from eating your launch week.
Send the brief and a shortlist comes back inside 48 hours. The full flow, brief to shortlist to milestone release, is laid out in how to hire a freelancer, and platform features covers messaging, file handoff and milestone tracking. Building something bigger than an app? We also match freelance AI developers, Shopify developers, WordPress developers and bookkeepers through the same four-stage screen.
FAQ
Senior US freelance mobile app developers charge roughly $80 to $150 per hour. Native iOS and Android specialists sit in the middle of that band, cross-platform React Native and Flutter developers slightly lower, and developers who handle both the app and its backend at the top. A small single-platform app usually lands between $18,000 and $45,000, priced as fixed milestones you fund in escrow.
Build native when the app leans hard on the camera, Bluetooth, background location, heavy animation or platform-specific hardware. Choose React Native or Flutter when you need both stores covered on one budget and the app is mostly screens, forms, lists and API calls. Cross-platform typically saves 30 to 40 percent versus two native codebases, and you can still drop into native modules where a feature demands it.
A focused MVP with authentication, a handful of core screens and one integration usually takes 8 to 14 weeks with one senior developer. Add payments, offline sync, real-time features or a second platform and you are looking at 4 to 7 months. App Store and Google Play review adds a few days per submission, so plan your launch date with that buffer built in.
Download two apps they shipped and use them for ten minutes. Ask who owned the App Store submission, how they handled a rejection, and what they would change about the architecture now. Request a walkthrough of real code covering state management and offline behavior. On SuperGig, every mobile developer clears a four-stage screen before you ever see the shortlist.
