App Development

iPhone, Android and web apps
designed and built by one team

From the first sketch to the App Store and Google Play. We design the screens, build the app and the admin panel behind it, test it on real phones, publish it, and keep it running after launch.

Sample screens: a clinic-booking app on iPhone and a delivery tracker on Android.

iOS + Android

Native, or both from one codebase

Design first

A prototype you can tap through before we code

Store-ready

App Store and Google Play submission handled

It's yours

Code, designs and store accounts in your name

Platforms

Every screen your customers use

Native iPhone and Android, one codebase for both, or a web app that installs from a link. We recommend the right one for your budget and your users.

iOS apps

iPhone, iPad and Apple Watch

Native Swift apps that feel at home on an iPhone: the gestures, the navigation and the details Apple users expect.

  • Designed to Apple's Human Interface Guidelines
  • Face ID, Apple Pay and Sign in with Apple
  • Widgets, push notifications and offline mode

Android apps

Phones, tablets and Wear OS

Kotlin apps built on Material Design 3 that run smoothly on flagship phones and on the budget handsets most customers actually own.

Cross-platform apps

One codebase, both stores

Flutter or React Native when you need iPhone and Android together. Usually the quickest and most cost-effective way into both stores.

  • One team and one codebase for iOS and Android
  • Native modules where the platform matters
  • Shared design system across both apps
  • Updates ship to both stores together

Web apps & PWAs

In the browser, installable on any device

Fast web apps and progressive web apps that install from the browser, work offline and need no store approval. Also the admin panel behind every mobile app.

  • Installs to the home screen from a link
  • Works offline and syncs when back online
  • Admin dashboards and staff portals
  • Chrome extensions and browser tools

App design

Designed for iPhone and Android, not squeezed onto them

iPhone users expect Apple's patterns. Android users expect Material Design. We design each so it feels native, then you tap through the prototype before we write any code.

iOS

Human Interface Guidelines, tab bars, large titles, SF Symbols, swipe-back.

Android

Material Design 3, dynamic colour, bottom sheets, FABs, system back.

Research & user flows

Who uses the app, what they need to get done, and the shortest path to it.

Wireframes

Every screen sketched in grey first, so the structure is agreed before the colours.

iOS & Android UI

Designed in Figma to Apple's guidelines and Material Design 3, so each app feels native.

Clickable prototype

Tap through the app on your own phone and show it to customers before a line of code.

Design system & dark mode

Colours, type and components defined once, light and dark, so the app stays consistent as it grows.

Icon, splash & store art

App icon, launch screen, store screenshots and preview images that make people tap Install.

Accessibility

Readable text sizes, strong contrast and screen-reader labels, so everyone can use it.

Arabic & right-to-left

Layouts that flip properly for Arabic, plus any other language your customers speak.

What we build

If your business runs on a register, a spreadsheet or a WhatsApp group, there is probably an app that would save you hours. These are the kinds we build most.

How it works

From idea to the App Store

You see progress every week, on your own phone, from the first sprint to launch day.

01
1

Discovery call

We learn the idea, the users and the must-haves, then agree the scope and a fixed price.

02
2

UX & design

Wireframes, then full iOS and Android designs and a prototype you can tap through.

03
3

Build in sprints

A new build on your phone every week through TestFlight or Play Console testing.

04
4

Test on real devices

iPhones and Android phones old and new, slow networks, edge cases and payments.

05
5

Store launch

Listings, screenshots, privacy forms and review. We see it through to approved.

06
6

Support & updates

OS updates, fixes, new features and performance checks after launch.

App Store & Google Play, handled

  • Apple Developer and Google Play accounts set up in your company's name
  • Store title, description, keywords and screenshots written and designed
  • Privacy policy, data-safety and app-privacy forms completed
  • Checked against App Store and Play review guidelines before submitting
  • Staged rollout, so problems reach a few users rather than everyone
  • Crash reporting and analytics running from day one

Already have an app?

  • Take over an app another developer left half-finished
  • Fix crashes, slow screens and bad store reviews
  • Update an old app for the latest iOS and Android versions
  • Redesign an app that works but looks dated
  • Add an iPhone version to an Android app, or the other way round
  • Move from two separate apps to one cross-platform codebase

Questions

What people ask before building an app

If you need both iPhone and Android and the app is mostly screens, forms, lists and payments, cross-platform (Flutter or React Native) is usually the faster and more economical route. If the app leans hard on the camera, Bluetooth, heavy graphics or platform-specific features, native Swift and Kotlin is the better fit. We recommend one on the discovery call and explain why.

It depends on the screens, features and platforms, so we don't publish a price list. After a short call we send a written scope with one fixed price, so you know the full cost before anything starts. No hourly meter and no surprise invoices.

A focused first version is usually a matter of weeks to a few months, depending on scope. You get a timeline with the quote and a new build on your phone every week, so you always know where it stands.

Yes. We set up or use your developer accounts, prepare the listings, screenshots and privacy forms, submit the app and handle any review feedback until it is approved. The accounts stay in your company's name.

Yes. Once the project is paid for, the source code, designs and store listings belong to you. We hand over the repository and the documentation.

Yes. Most apps need a server, a database, APIs and a web dashboard to manage users, content and orders. We build and host those as part of the same project.

Yes. We review the code first, tell you honestly what state it is in, then fix, update or rebuild the parts that need it.

We offer ongoing care: updates for new iOS and Android versions, bug fixes, monitoring, and new features as your users ask for them.
