Mobile applications

Your application. On iOS and Android.

I design and build mobile applications for businesses, from the first user flows to the backend and store release preparation. You work directly with the person building your product.

WHAT WE CAN BUILD

From features to a working product.

01

Scope and UX/UI

We define the audience, the problem and the first version. I design the main screens and navigation before development starts.

02

Two mobile platforms

I use React Native and Expo to develop for iOS and Android with a shared codebase. Device-specific features are assessed and tested for each project.

03

Backend and integrations

The agreed scope can include sign-in, accounts, a database, notifications, payments and connections to existing services. We also define how you will manage content.

04

Testing and release

I test agreed scenarios on both platforms and prepare builds and store materials. Accounts, access and responsibility for the submission process are agreed in advance.

YOUR PROJECT

The need first. Then the technology.

When is it a good fit?

For businesses creating a product, bringing a customer service to mobile or developing an existing application. The first version can focus on one essential workflow rather than the entire long-term idea.

How do we start?

We start with the product goal, key features and integrations. These form the basis of the scope, milestones and quote. An existing application's code and backend need a technical assessment first.

PRODUCT EXPERIENCE

From my own product to your project.

Naukado is my own educational product, available on iOS and Android. I am responsible for its design, application and ongoing development — experience spanning the interface and store releases.

FAQ

Before our first conversation.

What has the biggest impact on a mobile app quote?

Accounts and user roles, data storage, integrations, payments and offline behaviour matter alongside the screens. We separate launch requirements from later stages. External service fees and store accounts are agreed separately; they are not automatically included in development work.

What should I prepare for the first conversation?

Describe the audience and one main task they should complete in the app. Include the required platforms, essential features and existing systems. Mention any designs, budget constraints or target date. A finished specification is not required. Do not send passwords or customer data in the enquiry.

Can one application support iOS and Android?

Yes. React Native supports sharing a substantial part of the code. We assess platform requirements at the start and test the resulting builds separately.

How much does a mobile application cost?

The cost depends on features, screens, backend and integrations. I prepare an individual quote and schedule after discussing scope. An outline of your idea is enough for the first conversation.

Can you develop an existing application?

Yes, following an assessment of the technology, code and documentation. I first check what can be reused and which dependencies affect the work before agreeing on changes.
