Start with your idea
What would your app cost?
Answer 5 short questions. We’ll use your answers to prepare a proposal covering features, stages and development budget.
After discussing your project
- A scope for your first app version
- An iOS and Android recommendation
- An estimate of time and budget

Question 1 of 50%
One product. The right platforms.
iOS, Android or both
We recommend an approach based on your features and budget, and explain the trade-offs clearly.
For Apple devices
iOS app development
An interface that feels familiar on iPhone. Native Swift development suits apps that need deep integration with iOS features.
- Navigation designed for iOS
- App Store preparation
For Android devices
Android app development
An app for different screen sizes and supported system versions. Native Kotlin development, tested on real devices.
- Adapted to your target devices
- Google Play preparation
Two platforms
Cross-platform apps
A shared foundation for iOS and Android, for example with Flutter. We check whether it suits the features and integrations you need.
- Shared product logic
- Testing on both platforms
Designed to look good. Built to work.
Connected to your business
Bring a clear interface and your business processes together. A customer places an order — your team sees it in the system.
Customer accounts
Profiles, history and user roles.
Orders and payments
Purchases, bookings and status updates.
Notifications
Useful updates at the right moment.
CRM and APIs
Connect your website and business systems.
Admin tools
Manage content, orders and settings.
Product analytics
Understand how people use your app.
The app development process
See progress at every stage
We agree on the scope, share working versions and follow a clear delivery plan.
Discovery and first version
Explore your audience, key journeys and integrations. Decide what belongs in the MVP and what can come later.
Project scope and delivery plan
Prototype and design
Map the user journey and show how the screens will look. Agree on the interface before development begins.
Prototype and screen designs
Development and integrations
Build the app and backend, connect APIs and business systems. Share working builds as the product takes shape.
Working builds you can review
Testing
Check sign-in, forms, orders and payments on devices. Test weak connections, interruptions and error handling.
A tested version before release
Launch preparation
Prepare builds, descriptions and screenshots for the stores. Help with submission and responding to review feedback.
Release after store approval
Handover and development
Hand over code, designs and access as agreed. Plan support, updates and the next set of features.
Your product and a roadmap
Start at the right scale
App development priced around your project
You don’t need every feature on day one. We’ll help define a first version that solves a real customer need and estimate it before work begins.
An app MVP
One complete journey, such as choosing a service and booking it. A practical way to test an idea with real users.
- Priority features first
- A plan for future updates
A full product
Multiple journeys, user roles, integrations and backend logic. Suitable when your goals and requirements are clear.
- Complex journeys mapped out
- Connected business systems
What goes into the estimate?
Platforms, features, design, backend, integrations and testing. The proposal sets out stages, development fees and payment terms. Store accounts, hosting and paid services are accounted for separately. Store review timelines are determined by the platforms.
Your product stays in your hands
Source code and design
We agree on the handover of code, designs and rights before work starts.
Your accounts
Store accounts and infrastructure belong on the business owner’s side.
Support after launch
We agree separately on updates, tasks and response times.
Before we begin
Mobile app development questions
Can I start with just an idea?
Yes. Tell us who the app is for and what its users should be able to do. We’ll help turn the idea into user journeys and a scope for the first version. A detailed estimate follows once the features, platforms, integrations and backend requirements are clear.
Should I choose native or cross-platform development?
The choice depends on your features and product plans. Native development uses the tools of each platform separately. Cross-platform development provides a shared foundation but still requires platform-specific setup and testing. We check the required SDKs, device features and future maintenance needs before recommending an approach.
Can we launch an MVP and add features later?
Yes. An MVP should include one complete core journey, such as choosing a service and booking it, or placing and paying for an order. Other features can follow in later versions. This lets you use real customer behaviour to guide product decisions.
How long does mobile app development take?
The timeline depends on features, platforms, design and API readiness, integrations and approvals. Before work starts, we prepare a schedule with deliverables for each stage. Store review is a separate process; its timing and requests for changes are not entirely within the development team’s control.
Can the app connect to our website and CRM?
Yes, provided the systems have a suitable API or a way to exchange data. We check documentation, access, synchronisation rules and limitations at the start. A website and an app can share a catalogue, users and orders. If an API needs to be built, we include it as a separate part of the estimate.
Do you help with App Store and Google Play publication?
Preparation and submission can be included in the agreed scope. Release requires the product owner’s store accounts, listing materials, data disclosures and working features. We help with technical preparation and review feedback. Store approval and review timelines are decided by the platforms.
Who owns the source code and app accounts?
We agree on the handover of code, designs, documentation and rights before work begins. We recommend registering store and infrastructure accounts to the business owner and giving the development team role-based access. External libraries, licences and paid services are listed separately at handover.
Will the app need support after launch?
An app may need bug fixes, updates for new iOS and Android versions, server maintenance and new features. Support scope, response times, update frequency and fees are agreed separately. Tracking crashes and key user journeys helps guide improvements after launch.
