Delivery route
Choose the right mobile delivery route.
The right approach depends on your users, device features, release plan, current systems and long-term product roadmap. We recommend the route that fits the product rather than forcing every brief into one framework.
Delivery route
Best suited to
Key consideration
Delivery route
Native iOS
Best suited to
Apple-first products, deep iPhone or iPad features and platform-specific experiences
Key consideration
Separate iOS delivery using Swift and Apple frameworks

Testing demand, workflows and commercial assumptions before a larger investment
Key consideration
Prioritise the smallest release that can produce reliable evidence
End-to-end delivery
Mobile app development services for new and existing products.
From a first release to an inherited product, each capability connects technical work to a user, operational or commercial outcome.
Custom mobile app development
Build customer-facing or internal applications around the workflows, data and integrations your organisation actually needs. Custom mobile app development UK teams commission should remove operational friction and support a measurable product goal.
iOS and Android engineering
Deliver platform-specific applications when performance, device APIs, accessibility or ecosystem conventions justify separate native builds.
Cross-platform application development
Use React Native or Flutter where a shared codebase can shorten delivery and simplify maintenance without compromising the required experience.
Backend, API and system integration
Connect authentication, payment, CRM, ERP, analytics, messaging and other approved services through secure APIs and observable backend services.
Modernisation and rescue work
Audit an inherited mobile product, stabilise releases, reduce technical debt, improve performance or plan a staged move from an outdated stack.
App-store release and post-launch support
Prepare builds, release evidence and store submissions, then monitor, maintain and improve the product after launch.
Investment fit
When a mobile app is the right investment.
A mobile app earns its place when it gives users a clear advantage over a responsive website or existing system: offline access, location, camera, Bluetooth, push notifications, biometric authentication or a simpler field workflow.
A recurring service needs a faster route
Customers need a more personal and convenient way to reach a service they use often.
Teams work away from a desk
Field or operational teams need reliable access to workflows, data and approvals in context.
The product needs device capability
Hardware, notifications, offline behaviour or biometric authentication materially improve the experience.
A mobile channel can create measurable value
Retention, service delivery and data capture can improve when the mobile release solves a specific problem.
An existing app needs safer change
Modernisation, performance work and release-process improvements can reduce delivery risk without a needless rebuild.
Book a 30-minute project scoping call
Bring the product goal. We’ll clarify the delivery route.
A finished specification is not required. Process notes, screenshots, integration lists and an existing backlog are all useful. Tell us the business goal and current constraints; we’ll recommend a delivery route and prepare a fixed-price estimate once the scope is sufficiently clear.
- Initial response within four business hours
- Fixed-price estimate within two business days after sufficient scoping
- One-week trial sprint on a real backlog item where it fits
- Direct access to the engineers delivering the work
- Client owns the code from day one

Delivery commitment
What separates Capital Compute from other development agencies.
Outcome-based billing
For suitable engagements, a 2-week or 4-week sprint is agreed upfront and payment is tied to successful delivery of the agreed output. This model is already used with approximately half of Capital Compute clients.
One-week free trial sprint
Test the working relationship on a real backlog item before making a longer commercial commitment. The trial is designed to show communication, engineering judgement and delivery quality.
No charge for defects in our code
The same engineering team provides 90 days of post-launch support and fixes defects in Capital Compute-written code without an additional development charge.
AI-supported engineering with independent review
The engineering workflow uses documented markdown rules for each technology and domain, adds those rules to the build context, and applies pull-request review by a different model that has not seen the original code. Project documentation also captures decisions, common pitfalls and tribal knowledge so future work does not depend on one person.
Code ownership from day one
Repository, cloud, store and documentation ownership are agreed during scoping so the product does not become dependent on inaccessible vendor accounts.
Fixed-price estimate in two business days
Once requirements are clear enough to estimate responsibly, receive a scope-locked fixed-price estimate rather than an open-ended indicative range.

Frequently asked questions
Questions UK product teams ask before they commit.
Cost depends on platform coverage, product complexity, integrations, data sensitivity, design maturity, testing needs and release scope. Capital Compute provides a fixed-price estimate within two business days after the requirements are clear enough to scope.
Choose native delivery when platform-specific performance, device integration or ecosystem conventions are central to the product. Choose React Native or Flutter when shared delivery can meet the required experience and lower duplicated engineering effort. Discovery should test that decision against the product rather than relying on a general rule.
Yes. The first step is a codebase, architecture, dependency, security and release-process review. The findings determine whether to stabilise, modernise, migrate or rebuild specific parts.
The client owns the code from day one, subject to the agreed contract and any clearly identified third-party libraries or services.
The same engineering team provides 90 days of post-launch support. Defects in code written by Capital Compute are fixed at no additional development charge, and enhancements can be planned as separate sprints.
Yes. Discovery maps the required APIs, identity provider, CRM, ERP, payment, analytics and data flows. Integration risks and ownership are made visible before implementation.
Yes. Capital Compute supports UK organisations through remote discovery, scheduled overlap, direct engineer communication and written sprint evidence. The engineering team is based in Ahmedabad, India, so the delivery model is described clearly rather than presented as a UK-based team.
