App Design and Mobile App Development for Android and iOS
CreateWeb designs the UX/UI of your mobile or web app, and development for Android and iOS is done together with a trusted partner – you have one point of contact from idea to launch.
Our designers create the user flows, the prototype and the interface of every screen. A partner development team then turns the design into a working app, while we make sure the result looks and works exactly as approved.

Do you need a mobile app?
A mobile app makes sense when customers use your services often – orders, bookings, loyalty programmes or notifications.
For presenting a company or selling products, a well-built responsive website or online store is usually the better investment – see our website development and e-commerce development. That is why we start with a consultation and tell you honestly whether an app is the right choice.
What our app design service includes
App design includes user flows, information architecture, a prototype and the UI of every screen.

UI design
- Interface in your brand: colours, fonts and icons.
- Design for iOS and Android following each platform's guidelines.
- Screen states: loading, errors, empty lists.
Prototype and files
- An interactive prototype you can try on your phone.
- A design system with components for developers.
- Files ready for development and testing.
Mobile app development with our partner
Android and iOS development is done by a partner team of developers, while CreateWeb leads the project and the design.
You get a specialised development team without having to find one yourself. We hand over the design, take part in reviews and check that the finished app matches the approved interface. Publishing on Google Play and the App Store and ongoing maintenance are agreed in the development offer.
Web app design
We also design web apps – platforms, client portals and admin panels that run in the browser.
A web app needs no installation and works on any device. It suits internal systems, bookings, CRMs and client accounts. The process is the same – from user flows to an interactive prototype – and development is done by the partner team or your own developers.
Our process: from idea to Google Play and the App Store
The process has five steps, and each ends with your approval.
- Consultation: the app's goal, audience and core features.
- Concept: user flows and wireframes of key screens.
- Design: UI design and an interactive prototype.
- Development: the partner team builds and tests the app.
- Launch and support: publishing and updates.
How much app design and development costs
Design alone usually takes about 6–8 weeks; the price of development depends on the number of screens and features.
An app with a few screens and one with payments, accounts and an admin panel differ many times in scope. We quote after a consultation – separately for design and development, so you see each part clearly.

Why app design from CreateWeb
Our designers think about the user and the business at the same time, so the interface looks good and leads to action.
- UX before visuals – we test the flows before drawing screens.
- Prototype first – you try the app before any code is written.
- One contact – we coordinate design and development.
- Design experience – see our portfolio.
