iPhone app development

An iPhone app, built and put on the App Store.

We design it, build it and the server behind it, test it on your own phone, and take it through Apple’s review. One team for all of it, and a written price before any work starts.

Why it takes more than the screens

Apple turns away almost one submission in four.

In 2025 Apple reviewed 9.1 million app submissions and rejected 2.1 million of them. By its own account, more than 40% of unresolved review problems come down to a single rule, App Completeness: the app crashed, still showed placeholder text, or the reviewer couldn’t sign in.

None of that is about your idea. It’s preparation, and it’s the part we handle.

From idea to App Store

Five stops on the way to a live app.

  1. 1 · DesignDrawn before it’s builtEvery screen is designed and linked together, so you tap through the whole app on your own phone before any code exists.
  2. 2 · BuildThe app, and the server behind itAccounts, data and notifications live on a server we build alongside the app. One codebase, so Android can follow.
  3. 3 · TestOn your phone, through TestFlightYou and up to 10,000 invited testers install real builds with Apple’s TestFlight. Each build works for 90 days.
  4. 4 · ReviewThrough Apple’s App ReviewWe prepare what reviewers check and answer them if they ask. Half of submissions clear in a day, 90% within two.
  5. 5 · LiveOn the store, and kept currentListed under your business’s name. Since April 2026 every upload must be built with Apple’s current tools, so someone keeps it up to date.

What you’d get

An app, and everything that makes it a real one.

1

Designed to feel at home on iPhone

Layouts, gestures and text sizes that follow what iPhone owners already expect, including larger text and dark mode.

2

A working version on your own phone

You install real builds through Apple’s TestFlight as we go, so you are never judging from pictures.

3

Sign-in, including with Apple

Customers sign in with their email or their Apple account, and see only what is theirs.

4

Notifications

Reminders and updates that arrive even when the app is closed.

5

App Store submission

The listing, the screenshots, the privacy answers and the review itself, handled by us.

6

Android when you want it

One codebase, so an Android version is the same project and not a second bill.

The part nobody sees

An app on one phone is a prototype. What turns it into something customers can install and rely on is everything in this list, and it is most of the work. See what it takes ›

  • An Apple developer account in your business’s name
  • A server and database that hold the real data
  • Certificates and signing, renewed every year
  • A rebuild with Apple’s current tools each spring

How a project goes

  1. 1

    Talk

    A free call. You describe the problem in your own words, and we tell you honestly whether software is the answer.

  2. 2

    Proposal

    A written scope, timeline and price before any work starts.

  3. 3

    Build

    We design, code and test in phases. You see working software at the end of each one.

  4. 4

    Launch

    We put it live: app stores, hosting, domains, the lot.

  5. 5

    Keep it running

    Monthly maintenance if you want it: updates, fixes and regular reviews.

Before you ask

How long does Apple’s review take?

Apple says it typically reviews at least half of submissions in under 24 hours and 90% in under 48. We plan the launch date around that, prepare what reviewers ask for, and answer them if they come back with questions.

Do I need a Mac or a developer account?

You need an Apple developer account in your business’s name, which costs $99 a year in the US and which we help you open. You don’t need a Mac: you test on your own iPhone.

Can the app take payments?

Yes. What you sell decides how. Physical goods and services you deliver in person use ordinary card payments; digital goods used inside the app generally go through Apple’s own purchase system. We tell you which applies before we start.

Will there be an Android version?

When you want one. The app is written so the Android version comes from the same code, not from a second project.

What happens when a new iPhone system comes out?

Every autumn Apple releases a new version, and every spring it requires uploads to be built with its newest tools. An app nobody maintains eventually can’t be updated. Monthly maintenance covers this, or you can ask us when it’s needed.

Tell us what’s slowing you down.

Two taps and your email. No call to book, no brief to write.
