Mobile app development in Egypt — iOS and Android

We design and build iPhone and Android apps people keep on their home screen — from a pencil sketch to the App Store and Google Play, like Wago for pet care and Saadk for home services.

Your business, in every pocket.

We design, develop and support apps for iPhone, iPad and Android — native or cross-platform — from a simple prototype all the way to the Google Play Store and the Apple App Store.

Everything an app needs to succeed

  • iPhone & iPad apps — Designed the way Apple users expect and prepared for the App Store review.
  • Android apps — For every screen size, built and published on Google Play.
  • One app, both stores — A cross-platform app with Flutter or React Native when one codebase fits best.
  • The system behind it — The admin dashboard, the API and the database that run the app every day.
  • Payments & bookings — Cards, wallets, Apple Pay and Google Pay, Tamara and Tabby, calendars and slots.
  • Notifications & growth — Push notifications, offers, ratings and analytics that bring people back.

Every app we make starts on paper

Before a single line of code, we draw. A pencil sketch is quick to change and easy to discuss, so we can test the idea with you and with real users while changes still cost nothing. Then the sketch becomes a wireframe, and the wireframe becomes the design you will see on your phone.

User flow — booking a home service on Saadk

  1. Choose a service
  2. Pick the jobs
  3. Compare companies
  4. Date & time
  5. Pay

Sketch

Pencil on paper: what goes on each screen and how people move between them.

Wireframe

The same screen in grey boxes — sizes, spacing and hierarchy, before any colour.

UI design

Colour, type, icons and real content, turned into a clickable prototype you can try on your phone.

  • Thumb first — The main actions sit where one thumb reaches them.
  • Few taps — Every step that is not needed is removed from the flow.
  • Arabic and English, natively — Right-to-left screens designed as carefully as left-to-right ones.
  • Fast on any network — Light screens, cached content and clear loading states.
  • Accessible — Readable sizes, strong contrast and labels for screen readers.
  • Feels at home — Gestures and patterns people already know from iOS and Android.

A home service, booked in six screens

  1. Choose a service — The home screen opens on what people came for: AC, plumbing, electrical, appliances and more — each one tap away, with the wallet balance at the top.
  2. Narrow it down — Sub-categories keep long lists short, so finding the right service never feels like searching.
  3. Pick the jobs — Customers tick exactly the jobs they need, so the companies can price the work accurately.
  4. Compare approved companies — Only approved companies appear, side by side with their price and rating — the decision is clear.
  5. Choose a date and time — A simple calendar and time slots that are really available — no back and forth by phone.
  6. Pay your way — Wallet, card, Tamara or Tabby: the payment step offers the options people in Saudi Arabia actually use.

From idea to the app stores

  1. Discovery — Who the app is for, what it must do first, and what success looks like.
  2. Sketches & flows — Pencil sketches and user flows, reviewed with you screen by screen.
  3. Wireframes & prototype — A clickable prototype you can tap through before anything is built.
  4. UI design — The final look: colour, type, icons and motion, for iOS and Android.
  5. Build & test — Development in short cycles, tested on real devices through TestFlight and internal testing.
  6. Launch & grow — Store listings, release, then updates, analytics and new features.

Mobile app development in Egypt — for Android and iOS

A mobile app puts your service one tap away from your customers. We design, develop and support apps for Android phones, iPhone and iPad — from the first prototype to publishing on Google Play and the App Store.

Every app starts with the journey your users take: booking a service, buying a product, following a request. We design that journey first, then choose the right way to build it.

Android app development

Apps for Android phones and tablets, built and published on Google Play — like the Wago pet-care app, with its store, vet bookings and pet profiles.

iOS app development

Apps for iPhone and iPad, prepared for the App Store and designed the way Apple users expect.

Native or cross-platform

One cross-platform app (for example with React Native) for both stores, or native apps where a project needs them — we recommend the approach after discovery.

Who it’s for

  • Service businesses that take bookings, orders or requests from customers
  • Online stores that want a shopping app of their own
  • Startups testing an idea with a prototype before a full launch
  • Companies that already have a website or system and need an app that works with it

What an app gives your business

  • Always with your customers — Your service on the home screen, not lost in a browser tab.
  • Faster repeat use — Saved profiles and history make the next booking or order quicker.
  • Flexible payment — Payment flows such as wallet, card, Tamara and Tabby — as built for the Saadk app.
  • Support after launch — Updates and ongoing support once the app is live.

Common questions

Do you build apps for both Android and iOS?

Yes — for iPhone, iPad and Android, either as native apps or as one cross-platform app.

Do you publish the app on Google Play and the App Store?

Yes. We take the app from prototype all the way to the Google Play Store and the Apple App Store.

Can we start with a prototype?

Yes. Many projects start with a simple prototype to test the idea before the full build.

What happens after the app is launched?

We stay for updates and support — ongoing support is part of our mobile app service.
