Most UK SMEs who ask for a mobile app do not actually need a mobile app. They need a fast mobile website or a progressive web app that lives on the home screen. We will tell you that on the first call. When you do need a real native app — because you need camera access, offline mode, push notifications, secure biometric auth, or you are building a product that lives on the phone — we build it properly with React Native or native Swift/Kotlin, depending on the constraints.
Every app we ship goes through the real App Store and Play Store review process (we handle the submission, the metadata, the screenshots, the Apple review emails). Every app has crash reporting, analytics, and a plan for updates. No half-finished apps sitting in TestFlight forever.
What's included in a mobile app build
The shape of a typical engagement. Every project is scoped individually — this is what we reach for by default.
Native or cross-platform — chosen honestly
React Native when both stores need the same app and performance is not the bottleneck. Native Swift/Kotlin when you need platform-specific performance or features.
Offline-first architecture
Data caching, background sync, graceful offline states. Apps that work on the Tube, not just in the office.
Push notifications done right
Targeted, consent-based, compliant with UK marketing rules. No daily spam that gets your app deleted.
Auth, biometric & secure storage
Face ID / Touch ID on iOS, biometric on Android, secure keychain/keystore for tokens. No plain-text secrets.
App Store & Play Store submission
We handle the review submissions, asset generation, compliance forms, rejection handling, and the Apple "we need to see a demo" emails.
Crash reporting & analytics
Sentry or similar wired in, GA4/Firebase analytics, crash-free rate tracked. You see how the app is doing in the real world.
Who this is for
- UK businesses who genuinely need mobile-only features (camera, offline, push, biometric) — not just a website that feels like an app.
- Founders building a product whose primary home is the phone, not the browser.
- Service businesses whose customers are on-site engineers, drivers, or field staff who need an app that works without signal.
- Teams tired of half-finished app projects from agencies that disappeared mid-build.
How we build it
Reality check call
Fifteen minutes. Do you actually need a native app, or does a fast mobile website or PWA solve the problem for a tenth of the cost? We tell you the honest answer.
Scoping & prototype
Interactive prototype of the core user flows before any native code is written. Cheap to change, expensive to skip.
Build & beta
Iterative build with weekly TestFlight/Internal Testing drops so you use the real app, not just screenshots.
Store submission & launch
We handle App Store Connect, Play Console, metadata, screenshots, review forms, and any Apple back-and-forth. You approve, we submit.
Typical engagement ranges
Honest ranges, not a rate card. Every SoftwareYeah quote is tailored in writing after a free discovery call — these are the bands most projects land in.
Cross-platform build targeting one store initially, core user flows, auth, push, store submission handled end-to-end.
Dedicated Swift and Kotlin builds where performance or platform features demand it. Offline, biometric, deep integrations.
Projects with FCA, PCI-DSS, or equivalent compliance requirements. Quoted individually after a scoping session.
Mobile app quotes depend on whether we go cross-platform or native, how many integrations are involved, and the store review complexity. A simple React Native MVP is nothing like a regulated fintech iOS app. Discovery call first, written scope and price after.
