Mobile App Development

iOS and Android apps, built once.

We build mobile apps for iOS and Android from one codebase, connected to the same backend as your website. We also handle publishing to the App Store and Google Play.

The problem

Building separately for iPhone and Android means two apps, two budgets and two sets of bugs. Most small businesses and startups can't afford that, so the app never gets built or ships half-finished.

01How we work

Four steps, no surprises.

  1. 01

    Decide what version one does

    We list every feature you want, then sort them into "now" and "later". A short, clear version one is how an app ships on time at a fixed price.

  2. 02

    One codebase for both phones

    Most apps are built with React Native, which runs on iPhone and Android from the same code. When an app relies heavily on the device, we write native Swift for iOS.

  3. 03

    Test on real devices

    You install test builds on your own phone throughout the project and see the app take shape week by week.

  4. 04

    Store submission

    Screenshots, descriptions, privacy details and review: we handle the App Store and Google Play submission, and the resubmission if a reviewer asks for changes.

02What's included

What mobile app development includes

01

iPhone and Android

Both platforms from day one, with the same features on each.

02

Shared backend

If you have a website or web app, the mobile app uses the same accounts and data. Nothing to keep in sync by hand.

03

Push notifications

Reminders and updates sent to the right person at the right time, set up on both platforms.

04

Works with poor signal

The important screens keep working when the connection drops and sync once it is back.

05

Face ID and secure login

Sign-in that is quick for users and safe for your data.

06

Store publishing

App Store and Google Play listings, screenshots and review handled for you. The accounts stay in your name.

03Common questions

Before you ask.

Yes. That is usually the point: one set of accounts, one database, no duplicate data.

Usually one to three days. Rejections happen, especially on a first submission, and we handle the fixes and resubmission.

React Native for most apps, because one codebase covers both phones. Native Swift when the app depends heavily on device features. We built our own client app natively in SwiftUI, so we know both.

iOS and Android update every year and apps need small fixes to keep up. We offer maintenance plans, or hand over a documented codebase to your team.
