Mobile apps, built and published to both stores.

We build iOS and Android apps and take them through review to the App Store and Google Play, so the project ends with something people can download.

In short

What does mobile app development include?

It is the whole path from idea to a listing customers can install. We build one codebase that runs on iOS and Android, connect it to the backend and services it needs, and handle the store submissions, which is where most first-time app projects stall.

What is included

  • One codebase serving iOS and Android
  • Interface design that follows each platform's conventions
  • Backend, database and push notifications
  • App Store and Google Play submission, including review
  • Store listing assets, screenshots and descriptions

Who this is for

You will recognize yourself here.

Founders with an app idea

You have the concept and the market, and you need a team that has shipped through store review before.

Businesses going mobile

Your customers already use you on the web, and the phone is where the relationship actually lives.

Teams with a stalled build

Someone started the app, it never reached the stores, and you need it finished rather than restarted.

Products needing a companion app

The platform works, and the mobile piece is what makes it usable in the field or on the move.

Deliverables

What you end up with.

Everything below is handed over at the end of the project. Nothing on this list depends on us staying involved.

Process

How the work actually runs.

  1. 01

    Scoping the app

    We map the screens and the flows, and agree what ships in version one against what waits for the first update.

  2. 02

    Design

    We design every screen before building, so the review happens on images rather than on code that has to be rewritten.

  3. 03

    Build

    We build in increments and give you installable builds throughout, so you are testing on your own phone long before launch.

  4. 04

    Store submission

    We prepare the listings, submit to both stores and handle review feedback until the app is approved and live.

  5. 05

    Support

    We stay on after launch for the crashes and edge cases that only appear once real devices are involved.

FAQ

Questions we get about App Development.

Do you build for both iOS and Android?

Yes, from a single codebase built with React Native. You get both platforms without paying to build the same product twice.

Do you handle the App Store submission?

Yes, including review feedback. A project that ends with an unsubmitted binary is not a finished project.

How long does app development take?

Most start at eight weeks, plus store review, which is usually days rather than weeks but is not fully in anyone's control.

Do I need my own Apple and Google accounts?

Yes, and they should be in your company's name, not ours. We walk you through creating them and never hold your listings hostage.

Can you update an app I already have?

Often yes. We audit the existing codebase first and tell you honestly whether extending it is cheaper than rebuilding it.

What about ongoing store updates?

We document the release process so your team can ship updates, and stay available for the releases you would rather not run alone.
