We design, build, submit and support mobile apps for UK businesses — through Apple App Review and Google Play review, to live on both stores.
Product strategy, UX, engineering, release management and post-launch iteration handled by one senior team, with marketing built in from day one rather than bolted on after launch.

An app development company takes a business idea and turns it into a working mobile app: defining scope, designing the interface, engineering it for iOS and Android, submitting it for Apple and Google review, and maintaining it after launch. Creative Marketing does all five in-house for UK businesses, including full store approval.
| Typical MVP build time | 10–16 weeks from kick-off to store submission for a focused first version. |
|---|---|
| Apple App Review | Most submissions receive a decision within 24–48 hours, but rejections for privacy, account deletion or incomplete functionality are common on a first attempt. |
| Google Play new personal accounts | Google requires closed testing with a group of testers before production access, which adds time to a first launch. |
| Platforms we build on | Swift / SwiftUI, Kotlin / Jetpack Compose, React Native and Flutter. |
| Store accounts | Apple Developer Program and Google Play Console accounts stay in your company's name and ownership. |
| What you own | Source code, repositories, backend, store listings and analytics — all transferred to you. |
App development is the full path from idea to a live listing: defining what the app is for, designing how it works, engineering it for iOS and Android, passing store review, and keeping it healthy after launch.
The build is only half the job. Apple's App Review Guidelines and Google Play's policy, testing and Data Safety requirements reject a meaningful share of first submissions, so we scope compliance, privacy and store readiness from the first week rather than discovering them at the end.
We work across native (Swift, SwiftUI, Kotlin, Jetpack Compose) and cross-platform (React Native, Flutter), and we recommend whichever genuinely fits your product, budget and roadmap — not whichever we'd prefer to build.
Every engagement is built around measurable commercial impact — from revenue and leads to retention, efficiency and operational scale.
Discovery workshops, user journeys, MVP definition and a build plan with honest timelines.
Swift and SwiftUI apps for iPhone and iPad, TestFlight distribution and App Store Connect release management.
Kotlin and Jetpack Compose apps, Play Console closed testing, Data Safety and staged rollouts.
Scalable backends, authentication, payments, push, CRM and third-party integrations.
UK GDPR, privacy manifests, account deletion, permissions and guideline review before we submit.
Listing copy, keywords, screenshots and review strategy so the app is findable once it's live.
Event tracking, cohorts, push and lifecycle messaging so you can see what keeps users coming back.
OS updates, policy changes, monitoring, fixes and a steady cadence of new versions.
You need a credible team to take an idea to an approved, live app without burning the runway.
Established businesses adding loyalty, ordering, booking or service apps to an existing customer base.
An app that's dated, unstable or unsupported and needs rebuilding on a modern stack.
Bespoke apps for operations, engineers and sales teams, often with offline use and integrations.
Users, problem, MVP boundary, platform decision, compliance requirements and a fixed build plan.
Wireframes, UI design and an interactive prototype tested with real users before engineering starts.
Two-week sprints with working builds on TestFlight and Play internal testing so you see progress.
Store assets, privacy declarations, review readiness, submission and handling any review feedback.
ASO, analytics, retention loops and a release roadmap once real users are in the product.
Tell us what the app needs to do and we'll come back with a scoped feature list, a realistic timeline to App Store and Google Play approval, and an itemised cost — including what it costs to run, not just to build.
App cost is driven by scope rather than platform. The number of user roles, screens, integrations and compliance requirements moves the budget far more than whether you build for iOS, Android or both. We scope and itemise before quoting, and we include ongoing running costs rather than only the build.
A focused first version typically takes around 10 to 16 weeks from kick-off to store submission, including design, engineering, testing and store preparation. Larger products with multiple user roles, custom backends or regulated data take longer.
Yes. We handle submission and approval on both stores, including Apple's App Review requirements and Google Play's Data Safety, target API and testing requirements. We build to those requirements from the start rather than discovering them at submission.
Cross-platform (React Native or Flutter) suits most business apps and removes a second codebase and a second maintenance stream. Native is the right call for heavy graphics, sustained camera or sensor processing, complex background work or deep OS integration. We assess your feature list before recommending either.
Yes. Source code, repositories, backend, store listings, analytics and the Apple and Google developer accounts are all in your company's name and transferred to you.
Usually yes. With a cross-platform build both stores are launched together. With native builds we can run iOS and Android in parallel or stagger them by platform priority.
Yes. We start with an audit of the code, dependencies, store accounts and compliance status, then tell you honestly whether it should be maintained or rebuilt.
Apps need maintenance: annual OS releases, store policy changes, security patches, monitoring and a release cadence. We offer ongoing maintenance and support, and we scope those costs before you commit to the build.
Yes. We are a marketing group first, so app store optimisation, paid user acquisition, analytics, retention messaging and attribution are handled by the same team that builds the product.
