Mobile app development

Mobile apps people keep on their phones

We design and build iOS and Android apps that are simple to use, quick to load and ready for the app stores.

What is mobile app development?

Mobile app development is the process of designing, building, testing and publishing applications that run on phones and tablets. Apps can be native for one platform or cross-platform, sharing most of the code across iOS and Android.

How we deliver

How we take care of your project

Every project has two phases: first we define the work together, then we deliver it in short loops until it is finished.

Phase ADefine
  1. A1

    Product definition

    • Clarify users, core tasks and success measures
    • Decide native, cross-platform or web app
    • Agree the scope of the first release
    Deliverable: product brief
  2. A2

    Design and prototype

    • Design key screens and navigation
    • Build a clickable prototype
    • Test it with real users
    Deliverable: tested prototype
  3. A3

    Plan and estimate

    • Plan backend, integrations and store requirements
    • Split into sprints
    • Confirm timeline and cost range
    Deliverable: build plan
Phase BDeliver
B1B2B3B4B5Repeat until finishedin short cycles
  1. B1
    Build

    We develop the app and backend in sprints.

  2. B2
    Test

    We test on real devices, networks and operating-system versions.

  3. B3
    Publish

    We prepare listings and handle store submission and review.

  4. B4
    Measure

    Analytics and crash reports show how people use the app.

  5. B5
    Update

    We ship improvements and keep up with platform changes.

In depth

Understanding mobile app development

Deciding what your app should do

A successful app does a small number of things very well. Before choosing technology we help you define the people who will use it, the one or two tasks that matter most and why someone would install it instead of using your website. That focus shapes the design, the budget and the first release.

Many ideas work better as a mobile-friendly website first. We tell you honestly when an app is not needed yet, and when features such as notifications, offline use, camera access or payments make an app worthwhile.

Native, cross-platform or progressive web app

Native apps are built separately for iOS and Android, offering the best performance and access to every device feature. Cross-platform frameworks such as React Native and Flutter share most code between both platforms, lowering cost and speeding up delivery for most business apps. A progressive web app runs in the browser and can be added to the home screen, which suits simpler needs.

We recommend one based on your features, audience, budget and long-term plans, and explain the trade-offs so the decision is yours.

From prototype to store and beyond

We design clickable prototypes and test them with real users before development. We then build in sprints, test on real devices, prepare store listings and handle submission and review. Release is the start, not the end: analytics, crash reports and user feedback guide updates.

Store accounts stay in your name, so you own the app, its listing and its reviews.

Why it works

Apps built for real use

We start with the person holding the phone.

Designed for thumbs

Clear flows, readable screens and fast interactions that suit one-handed use.

Native or cross-platform

We recommend the approach that fits your budget and the features you need.

Secure and reliable

Safe data handling, sensible permissions and crash monitoring from the first release.

Included

Apps we build

Typical products.

Customer apps

  • Booking, ordering and loyalty
  • Account and payment features
  • Notifications and in-app messaging

Business apps

  • Field and delivery tools
  • Inspection and reporting
  • Staff and task management

Content and community

  • Media and learning apps
  • Social and community features
  • Offline access
Avoid

Common mistakes and how to avoid them

Building too many features first

Launch with the core task and add features once people use it.

Not testing on real devices

Behaviour varies across phones; test widely before release.

No plan for getting users

An app needs promotion; plan acquisition and retention alongside the build.

Forgetting store rules

Apple and Google reviews have requirements; we plan for them from the start.

Cost

What affects the cost

Every project is quoted individually. These are the main factors.

Factor

Platforms

What it means

One platform costs less than two; cross-platform frameworks reduce the difference.

Factor

Number of screens and features

What it means

Each feature, such as payments, chat or maps, adds design, build and testing.

Factor

Backend and integrations

What it means

Accounts, data storage and connections to other systems are often the larger part of the work.

Factor

Design level

What it means

Custom animations and illustrations increase effort compared with standard components.

Factor

Ongoing updates

What it means

Operating systems change every year, so budget for maintenance.

Illustrative scenario

a salon booking app

A group of salons takes bookings by phone and messaging apps. Clients forget appointments and staff spend hours rescheduling.

This is an example to show how we work, not a client story.

  1. 1

    We define the booking, reminder and rescheduling flows.

  2. 2

    We build a cross-platform app with push reminders and a staff view.

  3. 3

    We connect it to the salons’ calendar system.

  4. 4

    We track repeat bookings and adjust reminders based on results.

Estimate your app project

Answer a few questions and we reply with a clear scope, timeline and cost range. No obligation.

Technology

We choose tools to fit your goal, not the other way round. Typical choices:

  • Swift
  • Kotlin
  • React Native
  • Flutter
  • Firebase
  • Node.js APIs
  • Push notifications
  • App store compliance
Glossary

Key terms explained

Plain-language definitions of terms you will meet on this kind of project.

Native app
An app built specifically for one operating system, using its own tools and languages.
Cross-platform
An approach that shares most code between iOS and Android.
Push notification
A message sent to a user’s device by your app, even when it is closed.
App store review
The check Apple and Google perform before an app or update is published.

Questions, answered

Short answers to what people ask us most about mobile app development.

Ask us directly
Should I build for iOS, Android or both?

It depends on your audience. Cross-platform development often reaches both at a lower cost, and we explain the trade-offs before you decide.

Do you publish the app for me?

Yes. We prepare store listings and handle submission and review.

Can the app work offline?

Yes, where the use case needs it, with data syncing when the connection returns.

Who pays the app store fees?

Store developer accounts are in your name and paid by you, so you own the app and its listing.

How long does it take to build an app?

A focused first version typically takes a few months from kickoff to store release, depending on features. We give a schedule after discovery.

Can you update my existing app?

Yes. We review the code and design, fix issues and add features, or recommend a rebuild if that is cheaper in the long run.

Do you handle the app store submission?

Yes. We prepare listings, screenshots and compliance information, and manage submission and review.

What about maintenance?

We offer plans for operating-system updates, bug fixes, monitoring and new features.
