For an app that behaves once it leaves the simulator

Hire Mobile App Developers

An app can behave perfectly in a simulator and still lose data or reject users the moment real connectivity and real store review get involved. These developers are tested against those exact failure points, then placed to carry the platform judgement a specific framework specialist is not scoped to own.

  • Profiles typically within two business days
  • Replacement Assurance: If an engineer is not the right fit, a replacement from our own team starts within ten business days of your request, at no extra cost
  • You interview before placement if you want to
  • At least four hours a day inside your core working hours. Two hours plus a daily written handover for the US West Coast
  • 14-Day Risk-Free Trial: For your first engineer on a time-and-materials engagement. Up to 14 calendar days or 80 logged working hours, whichever comes first. End within the trial and pay nothing for trial hours. Continue beyond it and those hours are billed at the agreed rate. Unpaid trial work remains ours if you stop

01Published, not promised

The assessment behind every developer we send.

The mobile bar is published, not assumed: five competencies, the exact task behind each, and the shortcut that ends a candidacy. Most interviews ask which framework someone prefers. This one asks whether the app actually behaves once real users and real connectivity get involved.

What we listen forWhether the choice fits this app's actual needs, not a default preference.

The task we set

A startup needs an app on both iOS and Android within a tight budget and timeline. Propose your platform approach.

What strong sounds like
Weighs performance needs, team size and platform-specific features explicitly before recommending native or cross-platform, defending either answer.
What gives us pause
Recommends cross-platform by default to save time without checking whether the app actually needs platform-specific capabilities.

02Who you actually meet

The bench, priced by seniority.

Three seniority tiers, priced honestly, and the engineers who fill each one today. Real names and photos take their place as soon as we can share them, and the standard stays exactly the same.

Engineer

Features scoped tightly enough to ship inside your review bar, every time.

The right first hire when your seniors already set the standard.

Senior

The hard module nobody else wants to own, taken end to end.

Ownership of a surface, without adding a manager to your headcount.

$2,700–3,400per month

Lead

The workstream's decisions, made daily, so nothing waits on a meeting.

One accountable voice for a pod or initiative that can't afford to drift.

03From stated problem to first change

Four steps, each closing on evidence.

This process is built around platform judgement, not a tally of frameworks used before. Nothing is charged for stopping partway through the four steps.

  1. Define the platform problem

    We map where your app's platform choice, sync design or store approval is actually under strain. The brief names that problem, not a framework preference to match.

    A brief your leads sign

  2. Match against your release train

    Candidates are screened against your actual platforms, your release cadence and your store history. Three developers who understand your release train beat thirty who list frameworks on a CV.

    Three fits, not thirty CVs

  3. Assess on the real tasks

    Your team can watch the offline-sync and app-store-review exercises directly. What shows up is platform judgement, not familiarity with the newest cross-platform framework.

    Evaluation you can watch

  4. Onboard inside your process

    Access, standards and a first bounded change inside your actual release pipeline. Continuity cover keeps a departure from ever becoming your release-day emergency.

04Evidence and proof

Developers who shipped an app that behaved in the field.

Mobile proof is an app that held up on real devices and real connectivity, not one that only worked in a simulator. Every record here waits for written client approval before production.

Tern · Logistics SaaS, EU

A field app that stopped losing data once sync handled conflicts on purpose.

Tern's field workers lost updates whenever spotty connectivity caused two changes to collide during sync. A mobile developer designed a deliberate conflict-resolution rule for the data involved, and the silent data loss stopped appearing in the field.

05Three shapes, one standard

Add a developer, a mobile pod, or a practice.

Most teams start with one developer working inside an app that already ships to real users. Some need a pod that owns the whole release train end to end. Where a mobile app needs building from nothing, we point you to the practice instead.

  • One named developer

    A single mobile developer inside your direction and your reviews. The smallest commitment, and the usual way engagements begin.

    Team extension

  • A mobile pod

    A pod with its own lead that owns the release train end to end, store submissions included. You set priorities while the pod carries delivery.

    Delivery pods

  • The practice, not the person

    When a mobile app needs building and shipping from nothing, not a role filled, mobile app development takes on that accountability instead.

Ask us directly Or browse every role
What does a mobile app developer actually do day to day?

Judges native-versus-cross-platform tradeoffs, designs offline sync that resolves conflicts on purpose, and gets an app through store review without a rejection cycle. Most of the job is handling what only shows up once real users and real devices are involved.

How is this different from hiring an iOS or Android specialist?

A platform specialist goes deep on one operating system's APIs and should be the choice once that platform is your whole scope. A generalist mobile developer is picked for judging native-versus-cross-platform tradeoffs before that scope is even fixed.

Can we run our own interviews as well?

Yes, the published tasks are built to be reused directly. Several clients now run the offline-sync exercise themselves in later hiring rounds.

How fast can a mobile app developer start?

A shortlist arrives within days from a bench evaluated continuously. The real start date after that depends on how quickly your side can open up the app store accounts and build pipeline.

Who manages the mobile app developer day to day?

Your engineering leads set the release priorities and hold the review standard. We carry what sits underneath that: payroll, continuity, and the replacement process if plans change.

What if the mobile app developer is not the right fit?

Flag it during the first few weeks and the replacement will not cost you anything further. We carry the specifics of the mismatch into the next match so it is not repeated.

Do your mobile app developers use AI coding tools?

Yes, for scaffolding boilerplate screens and drafting test cases across platforms. The platform judgement, the store-compliance decisions and every merge stay accountable to the developer.

How does pricing work for a hired mobile app developer?

A mobile developer's rate depends on whether the scope is one platform or both, and how much of the release process they own. The shortlist carries the actual monthly figure, billed monthly, notice-period exit, no placement fee added on top.
