A mobile app development company USA businesses can get through App Store review with.

Five published apps, one codebase per project, taken through Apple and Google review rather than handed over as a build file and a good-luck message. None of the five is American yet, and the cases below say so.

Where app projects go wrong

The build is the easy half.

Most app projects that disappoint did not fail at the engineering. They failed at the three things that happen either side of it, and all three are foreseeable.

Nobody owned the store submission

An app that compiles is not an app that ships. Apple rejects for reasons that have nothing to do with code — a missing privacy label, an account you cannot delete from inside the app, a sign-in option that has to be offered, a screenshot at the wrong size — and each round trip costs days. A mobile app development agency USA buyers should hire is one that treats review as part of the project with a named owner, not as something that happens to you after handover.

Two codebases were bought where one would do

Some apps genuinely need native builds on each platform. Most do not, and paying twice for the same feature set is the single most common way an app budget doubles for no user-visible benefit. The honest test is whether the app leans hard on platform-specific hardware or interface convention; if it does not, one codebase compiled to both stores costs less to build and considerably less to maintain, because every future change happens once.

The backend was an afterthought

An app is a window onto a system, and the system is where the work is. Accounts, roles, notifications, an admin side for whoever runs the business, and an API that will not have to be rewritten when the second feature arrives. Projects that budget for the screens and not for what is behind them run out of money at precisely the point the thing starts being useful.

What actually differs about shipping to American users

How it runs

You see the price at step two.

01

Teardown

Free, written, inside 48 hours — including whether you need an app at all or a better mobile site would do.

02

Scope and fixed price

Every screen, both platforms, the backend, and store submission named as a deliverable rather than assumed.

03

Build overnight

TestFlight and Play internal testing builds from early on, so you are using it on your own phone while we build.

04

Submit, launch and hand over

We take it through review. Developer accounts, repository and every credential stay in your name throughout.

Money

How we quote an app.

Fixed-scope app

One written scope covering both stores and the backend, one price in dollars, inside 48 hours of the discovery call. It moves only when you change the ask.

  • Free teardown first
  • Store submission included
  • Out-of-scope stated explicitly

App plus platform

Where the app is the front of a larger system — a marketplace, a booking platform, an operations tool. Quoted as one project so the seam between app and backend belongs to somebody.

  • One team, both halves
  • Admin side included
  • Phased if it is large

Takeover and recovery

An app that was abandoned mid-build, or one in the stores that nobody can update any more. Quoted once we have read the codebase and checked what account access actually exists.

  • Written assessment first
  • Continue-or-rebuild answer
  • Account recovery help

There is no rate card on this site, in any currency, deliberately. A published figure is either wrong for your app or padded enough to cover all of them. What is fixed is the process: free teardown, written scope, one price, agreed before anyone starts.

FAQ

Straight answers.

Do you build one codebase or two? And are you an iOS app development company USA clients would hire for Apple work specifically?
One codebase for most projects, compiled to both stores, and yes for Apple work within that. Our published apps are Flutter, which produces genuine native builds for both platforms from a single source — that is why one of them went from an empty repository to users in six weeks. If your app depends heavily on platform-specific hardware or interface convention, native is the right answer and we will say so rather than sell you the thing we prefer to build. The framework detail lives on its own page if that is what you came to assess.
Are you also an Android app development company USA businesses can use, or is Android an afterthought?
Both stores come out of the same build and neither is an afterthought, which is precisely the argument for doing it this way. Where they differ is in review and rollout rather than in code: Google's review is faster and more automated, staged rollouts are easier, and the device fragmentation means more testing on real hardware. That work is in the scope rather than discovered afterwards.
We are shortlisting a mobile app development company New York agencies compete with. What are we actually trading?
Hours against scope, and you should price it honestly. A Manhattan team shares your working day and can sit in a room with you; that is worth real money and for a product that changes weekly it is worth all of it. We are asleep during your entire working day and the same budget buys materially more engineering time. For a defined app with a written scope, the overnight cycle usually finishes sooner than a shared-hours team does. For a discovery-heavy product being figured out as it goes, hire locally — and we would tell you that on the call rather than after the deposit.
Who owns the developer accounts and the app listing?
You do, throughout — not transferred at the end. The Apple and Google developer accounts are registered in your company's name with your billing on them, and we work inside them with access you can revoke. This is the single most common place clients get trapped: an app published under an agency's account is an app you cannot update without them, and recovering it ranges from tedious to impossible.
What happens after launch?
Both platforms change every year, and an app left alone breaks eventually — an OS release, a store policy change, a library that stops being supported. Maintenance is a separate arrangement, scoped and priced after launch rather than bundled in to make the headline number look smaller. If you would rather take it in-house, the handover is designed for that: conventional framework, readable code, and a walkthrough for whoever inherits it.
How long does an app take?
The published apps give real numbers instead of a range invented for a sales page. RapidKill went from an empty repository to an app in users' hands in six weeks, because the scope was tight and the backend was Firebase. Just Book — a marketplace with two user sides, an admin and a Laravel platform underneath — took five months. Yours depends far more on the backend than on the screens, and the teardown gives you a real number before you commit.
