Mobile app development for iOS and Android

We build iOS and Android apps from one codebase, or native where the app needs it, and publish them under your App Store and Google Play accounts. Your customers or staff get one app that signs in once, works offline and sends only the notifications they want.

Who it's for

A business with repeat customers

Customers order, book or check status often enough to keep your app on their phone.

A team in the field

Staff need forms, photos, signatures and maps that work without signal.

A founder with a product

You need something in the stores that investors and early users can download.

What you get

  • One app for both stores

    iOS and Android from shared code, with native parts where the camera, maps or payments need them.

  • Sign-in and accounts

    Phone number, email, Apple or Google sign-in, with roles for customers and staff.

  • Push notifications

    Order updates, reminders and offers, sent by rule and never more than the user asked for.

  • Works offline

    Data is kept on the phone and synced when the connection returns.

  • Admin panel

    A web panel where your team manages users, content and orders.

The first two weeks

After two weeks the core screens run on your own phone through a test build, with sign-in and one real task working end to end.

After that

App Store and Google Play publishing

Payments inside the app

Tablet and desktop versions

Analytics and crash reporting

Scope it in 60 seconds

Three questions. You get the shape of the first two weeks and the stages after, and you can send it to us as your brief.

Built for our clients and running today.

Most of our work since 2007 is under NDA. These three we can show.

Questions buyers ask

How much does it cost to build an app?
It depends on the screens, what the app connects to and whether it needs native code. Tell us what it must do and we'll give you a clear idea, then plan it in stages, each with a date.
How long does it take to build a mobile app?
A test build is on your phone after two weeks. The full app is built in stages with written dates, with store review planned into the last stage.
Native or cross-platform?
Cross-platform for most business apps, because one codebase costs less to run. Native when the app depends on heavy graphics, the camera or special hardware; we say which and why.
Will the app be in my developer account?
Yes. It is published under your Apple and Google accounts, and the source code is yours.
