# Mobile app development

> We design and build mobile apps for iOS and Android in React Native, from UX and development through integrations to publishing and further development.

## Mobile app development for iOS and Android

We design, build and release your mobile app, then run it for the long term.

We connect it to your website, backend or internal systems. Where a project needs it, we also handle offline mode and data synchronisation.

### The apps we build

Not every project needs a native app. First we clarify what the app should do, who it's for and what technical requirements it must meet. Only then do we choose the right way to build it.

#### Cross-platform apps

iOS and Android apps from a single React Native codebase. A good fit when you want to cover both platforms without two separate development teams.

#### Progressive web apps

An app built on web technologies that people open straight in the browser. A good fit when you don't need everything a native app can do.

#### Apps for an existing product

A mobile extension of your website, portal or information system. We connect the app to your existing backend and API.

#### Offline-first apps

Apps that work without an internet connection and sync data once it's back. Well suited to field work or places with unreliable connectivity.

### What's included

We treat the app as one project, from the first design to release and ongoing operation. You don't have to coordinate a designer, developers, a backend team and store publishing separately.

**Mobile UX/UI design and prototype**

**iOS and Android development in React Native**

**Backend and API to suit the project**

**Push notifications and on-device data**

**Offline mode and data synchronisation**

**Integrations with your websites, systems and APIs**

**Testing on real iOS and Android devices**

**Publishing to the App Store and Google Play**

**Operation, updates and further development under an SLA**

### Who we build apps for

For companies and institutions that need a mobile app as **part of their product** or internal processes. That might be a customer or loyalty app, a mobile extension of an existing system or a tool for people in the field.

If the app works with important data, has to connect to your systems or must work without the internet, we design the architecture for that from the start.

### How an app comes together

First we clarify what the app needs to solve and how it fits into your existing systems. Only then do we choose the technology and start development.

[How we work](/en/about-us/how-we-work/)

**Analysis and specification**

We define features, user scenarios, platforms, integrations and technical requirements, then prepare the scope and an estimate.

**UX/UI design**

We design the key screens and user flows. You can click through the prototype before development begins.

**Development in sprints**

We build the app in increments and provide working builds for testing as we go.

**Device testing**

On real iOS and Android devices we test user scenarios, integrations and how the app behaves in different conditions.

**Publishing**

We prepare the app for release and take care of publishing it on the App Store and Google Play.

**Operation and further development**

After release we handle updates, compatibility with new operating system versions, support and new features.

### Technologies

For cross-platform apps we use React Native and, depending on the project, Expo. We choose a PWA where native features aren't needed.

We build the backend in Laravel or Node.js, for example, and connect apps to existing systems via API.

**We fit the technology to the project, not the project to the technology.**

### Why trust Webikon with your app

**Experience with apps for demanding environments**

For the UN we built an offline-first app that runs on the web, iOS and Android. It works with sensitive data that is often out of reach, so it has to work reliably offline and keep the data in sync.

**One codebase for iOS and Android**

Where the project suits it, we build both platforms at once in React Native. That makes further development and maintenance simpler.

**From design to the App Store and Google Play**

You don’t need another supplier for publishing, updates or technical operation. We are responsible for the project from design through to long-term development.

**A partner after release, too**

Our partnerships last more than 5 years on average. We can keep running, updating and developing the app as your product needs.

### Common questions about apps

If you can't find the answer here, write to us. We'll be glad to help.

[Ask us](/en/contact/)

**How much does mobile app development cost?**

The price depends on the number of features, platforms, integrations and technical requirements. With cross-platform development, iOS and Android can share a large part of the code, but the final price always depends on the specific project. After an initial analysis and specification, we'll prepare a concrete estimate.

**How long does app development take?**

A simpler app or an MVP can be ready within a few months. More complex apps with their own backend, integrations, offline mode or more demanding logic need more time. We develop in sprints, so you see working parts of the app as we go.

**Should we go native, React Native or PWA?**

It depends on what the app needs to do. React Native suits many projects where you need both iOS and Android and want to share part of the code. A PWA makes sense where an app available through the web is enough. Native development can be the right choice for specific platform or hardware requirements. We'll make a recommendation based on your project.

**Will you handle publishing to the App Store and Google Play?**

Yes. We prepare the app for publishing, help set up the necessary accounts and take care of the release. Later on we can also handle updates and new versions.

**Can you connect the app to our website or internal system?**

Yes. We can connect the app to an existing backend, website, portal or internal system via API. In the design we also cover authentication, data handling and other technical requirements.

**Can the app work without the internet?**

Yes, if the project needs it. With an offline-first architecture, people can use the app without a connection, and the data syncs once it's restored. We took this approach in the app for the UN.

**Who looks after the app after release?**

We can take it on for long-term operation and further development. We handle updates, compatibility with new versions of iOS and Android, technical support, monitoring and new features. We'll set up an SLA to suit your needs.
