Xapner

Mobile App Development for London & UK Businesses

Xapner plans, designs and develops mobile applications for businesses that need a practical customer, staff or operational product on iOS and Android.

The challenge

Native and cross-platform mobile applications for customer, staff and business workflows across London and the UK.

How Xapner approaches it

Mobile apps can give customers or staff a focused way to complete important tasks away from a desktop browser. Xapner defines the users, workflows, platform choice, backend connections and release scope before development begins, keeping mobile products distinct from broader CRM, ERP, POS, portal and internal-system work.

Mobile app capabilities

Mobile apps Xapner builds

Customer apps, staff tools and focused business applications shaped around a defined workflow, audience and measurable operational need.

Custom mobile app development

Bespoke interfaces and functionality are planned around the product rather than forcing a business process into a generic template.

iOS app development

iPhone and iPad experiences can be delivered natively or through an appropriate cross-platform codebase, based on scope and device requirements.

Android app development

Android applications are designed for the agreed devices, operating-system support and Google Play distribution requirements.

Flutter and React Native development

Flutter or React Native can provide one maintainable product codebase for iOS and Android when the required features and integrations suit a cross-platform approach.

Cross-platform vs native apps

Xapner compares user experience, device access, performance, delivery risk and long-term maintenance before recommending native or cross-platform development.

Business, staff and customer applications

Apps can support bookings, customer accounts, field work, staff tasks, approvals, dashboards and other agreed mobile workflows.

Backend systems and APIs

Secure APIs can connect an app to an existing CRM, ecommerce platform or operational backend, subject to available access and documented integration capability.

UX, UI and mobile-first design

Navigation, states, forms, touch targets and core journeys are designed for small screens and real mobile use before development is finalised.

Testing, launch and store support

The agreed scope can include device testing, release preparation and submission support for Apple App Store and Google Play. Store acceptance remains controlled by Apple and Google.

Ownership, handover and maintenance

Projects define source-code ownership, repositories, access and handover. Ongoing maintenance and phased development can be arranged separately after launch.

What is not included

  • App Store or Google Play approval
  • Third-party subscriptions, licences and platform fees
  • Device hardware
  • Backend, CRM or ecommerce work outside the agreed integration scope
  • Unlimited revisions or maintenance

Typical delivery

  1. Discovery and product scope. Define users, business goals, priority journeys, platforms, integrations and the first viable release.
  2. UX and technical planning. Map flows, interface states, data, API responsibilities, security considerations and the native or cross-platform approach.
  3. Design and prototype. Create mobile-first screens and interactions for review before full implementation.
  4. App and backend development. Build the approved application and agreed API, authentication, payment, notification or business-system connections.
  5. Testing and acceptance. Test important journeys, supported devices, permissions, integrations and release builds, then resolve agreed acceptance issues.
  6. Store preparation and launch. Prepare agreed listings and release files and support submission; Apple and Google independently control review and approval.
  7. Handover and ongoing development. Transfer agreed access and source materials, then continue with separately scoped maintenance or product phases where required.

Typical timeline

Delivery depends on product scope, platform choice, integrations, content, testing and store-review requirements. Discovery produces a written phased timeline; no fixed build time is assumed.

Ownership and handover

After agreed fees are paid, the client owns the bespoke source code and original deliverables created for the project, subject to third-party libraries, platform terms, licences and the written agreement. Xapner provides the agreed repositories, access and handover guidance.

Questions about this service

How much does mobile app development cost?

Cost depends on platforms, screens, workflows, backend requirements, integrations, testing and release scope. Xapner confirms a written scope and GBP price after discovery rather than publishing an unsupported fixed figure.

How long does an app take to build?

Timescale depends on scope, platform choice, integrations, content, testing and store review. Discovery produces a phased delivery plan; no fixed timescale applies to every app.

Does Xapner build both iOS and Android apps?

Yes. Xapner can build for iOS and Android using native or suitable cross-platform technology according to the agreed product requirements.

Should I choose Flutter, React Native or native development?

The choice depends on device features, performance, user experience, existing technology and maintenance needs. Xapner recommends an approach after technical discovery rather than treating one framework as universally best.

Can an app connect to an existing CRM or backend?

Yes, where the existing system provides suitable access or APIs. Xapner reviews authentication, data ownership, rate limits, security and integration scope before confirming delivery.

Who owns the source code?

After agreed fees are paid, the client owns bespoke source code and original deliverables created for the project, subject to third-party licences, platform terms and the written agreement.

Can Xapner publish apps to the App Store and Google Play?

Xapner can support release preparation and submission where included in scope. Apple and Google control developer-account eligibility, review, approval and ongoing store availability.

Does Xapner provide ongoing app support?

Yes. Maintenance, monitoring, compatibility updates and further product phases can be agreed separately after the included handover or support period.

Does Xapner work with businesses in London?

Yes. Xapner works with businesses across London and the wider UK through an agreed remote or project-specific arrangement. This page does not represent a London office.
