Mobile app development is one of the fastest categories to overspend in. Native iOS and Android development means writing the same app twice, in two different languages, with two separate teams. Cross-platform done badly means a clunky app that pleases nobody. Cross-platform done well, which is what is actually possible in 2026, means one codebase, one developer, one timeline, and an app that looks and feels native on both platforms.
I build with FlutterFlow + Supabase. That gets you iOS, Android, and tablets from one codebase, a clean admin backend you can manage yourself, and an app that is genuinely production-grade. App Store and Google Play submission included.
What I build
Bespoke mobile app development for internal workflows, customer experiences, and validated ideas that need to live on the home screen.
Cross-platform iOS & Android apps
Built with FlutterFlow and Supabase. One codebase serving iPhones, Android phones, iPads, and Android tablets, with native-feeling performance and significantly faster delivery than building twice.
MVPs and validated builds
The smallest version of your app that proves the idea and earns its keep with real users. Auth, core flows, and basic admin, built to ship in weeks rather than drift for months.
Internal team apps
Field-team apps, sales-team tools, inventory and barcode-scanning apps, and operational mobile tools that fix specific business workflows. Often integrated with your ERP, CRM, or back-office systems.
Customer-facing apps
Loyalty apps, booking apps, content apps, and direct-to-consumer mobile experiences. Push notifications, in-app purchases, and the engagement infrastructure that justifies having an app at all.
App Store & Google Play submission
The submission process is its own project: provisioning profiles, screenshots, privacy policies, app review responses, and production releases. Included as standard, not added as an awkward extra.
Backend & admin dashboards
Most apps need a web admin to manage content, users, reporting, and data. That backend is built into the project, so you are not buying a separate dashboard product later.
Why FlutterFlow + Supabase
FlutterFlow gets a lot of no-code associations it does not really deserve in 2026. Under the hood it is Flutter, Google's production framework used by apps across finance, automotive, retail, and consumer products. FlutterFlow is the visual interface to Flutter, with full custom code support where you need it.
In practice, you get the speed of low-code for most of the build - UI, layouts, basic flows, database connections - and custom code for the parts where it matters: complex logic, integrations, native features, and edge cases. One codebase, two app stores, less waste.
Supabase pairs with it as the backend: Postgres database, auth, storage, real-time subscriptions, and edge functions. No per-user pricing surprise from me, no data trapped in a black box, and a backend your team can understand.
FlutterFlow
Visual Flutter development with custom code support where the app needs it.
Supabase
Postgres, auth, storage, real-time subscriptions, and edge functions.
Backend
Clean data models, admin workflows, APIs, and integration logic.
Ownership
Your store accounts, your data, your code, your FlutterFlow project.
When this stack is not the right call
High-frequency gaming, AR-heavy apps, apps that need deep iOS-only integrations such as HealthKit or ARKit, and products backed by existing native teams. For those, native is still the answer.
How a mobile project actually works
A mobile app has extra moving parts: devices, beta builds, store review, push, analytics, and ongoing OS updates. The process needs to account for those from the start.
Discovery & validation
Before anything is built, we work out whether you should build a mobile app at all. Sometimes a mobile-optimised web app does the job for a fraction of the cost. If an app is genuinely the right call, you leave Discovery with a written spec, scoped phases, and a fixed quote.
Design & build
UX is designed in Figma and signed off before the build starts. Then you get weekly progress builds you can run on your own phone through TestFlight and Play Console, so you are not waiting until launch to see whether the app feels right.
Beta & App Store submission
Closed beta with real users, fixes, polish, then App Store and Google Play submission. Apple's review process can take 1-7 days; Play is usually faster. Both submissions are handled as standard.
Launch & iterate
Live in both stores, with the option to stay engaged on a flexible retainer for ongoing development, push notification campaigns, analytics, and version updates as iOS and Android move on.

Read case study →When mobile is the right answer
An app should have a reason to exist beyond "apps feel more premium". The best mobile projects use the device itself: location, camera, push, offline access, or the simple fact that the user needs the workflow in their pocket.
A mobile app is right when:
- Your users are on the move: field teams, drivers, sales teams, on-site staff.
- You need offline functionality, GPS, camera, push notifications, or device sensors.
- Being on the home screen matters for loyalty, booking, content, or repeat customer behaviour.
- The audience is genuinely mobile-first and the UX benefits from native patterns.
Mobile is probably wrong when:
- A responsive mobile web experience would do the job with less build and maintenance overhead.
- Your users only need it occasionally. Apps people use rarely get deleted fast.
- You do not have a plan for push, App Store optimisation, retention, or paid acquisition.
- The idea has not been validated and a smaller web MVP would answer the risky questions first.
If you are not sure, that is what Discovery is for. Sometimes the best mobile app developer UK businesses can hire is the one who says "build a web app first".

Frequently asked questions
Straight answers on mobile app development, FlutterFlow, app stores, and what happens after launch.
How much does mobile app development cost in the UK?+
Mobile builds vary widely. A focused MVP is a different conversation to a full customer-facing app with payments, push, and back-office. Discovery results in a fixed-price quote per phase. Cross-platform builds with FlutterFlow and Supabase typically come in significantly cheaper than native iOS plus Android builds because there is one codebase, not two.
How long does it take to build a mobile app?+
MVPs usually run 6-10 weeks. More complex apps with integrations, push, payments, and admin run 10-16 weeks. App Store and Google Play submission adds 1-2 weeks at the end because Apple review can take up to a week, occasionally longer.
Native vs cross-platform - which should I choose?+
For most business apps, cross-platform with FlutterFlow and Supabase is the right call: one codebase, two app stores, faster build, and a simpler maintenance path. Native iOS or Android is right when you need deep platform-specific features, high-performance gaming, advanced AR, or you already have native teams in-house. I will give you an honest answer in Discovery.
Will my app feel native on iOS and Android?+
Yes, when it is designed and built properly. FlutterFlow apps are built on Flutter, so they render fast, behave consistently, and can use platform-appropriate UI patterns. Most users cannot tell whether a well-built business app is cross-platform. The clunky feeling people associate with cross-platform usually comes from poor UX, weak architecture, or trying to force the wrong stack onto the wrong problem.
Do you handle App Store and Google Play submission?+
Yes. Store submission is included as standard. That covers provisioning profiles, app icon assets, screenshots, store descriptions, privacy details, release builds, and the back-and-forth with App Store Review where needed. App Store and Play Store accounts are set up under your business, so you own the listings from day one.
What about ongoing maintenance and updates?+
Apps need ongoing care more than websites do. Both stores require minimum SDK updates roughly annually, and every iOS or Android release can expose compatibility issues. Most clients stay on a flexible retainer covering maintenance, small feature improvements, analytics, and version updates. If you want your in-house team to take over, the project can be documented for that too.
Who owns the app and the code?+
You do. App Store and Play Store accounts are owned by your business, the FlutterFlow project is owned by your account, and any custom code or backend work is delivered into your GitHub or GitLab repo. No licensing, no hidden per-user fees from me, and no vendor lock-in.
Can I build a backend admin dashboard alongside the mobile app?+
Yes. Most mobile apps need one. Supabase gives you a database admin out of the box, and I build a custom web admin where the project needs more than that, such as content management, reporting, support tools, approvals, or user management workflows.
Can you integrate with my existing CRM, ERP, or website?+
Yes. Mobile apps that integrate with existing systems are a meaningful share of my work. APIs into Salesforce, HubSpot, Sage, Xero, Shopify, Magento, and bespoke endpoints are all standard. If the app is part of a wider custom app development project, the backend and integrations are planned together.
What is the first step?+
Book a Discovery call. It is 30 minutes, no pressure, and no obligation. We will work out whether mobile is the right answer for your project, what the first phase should include, and what can wait until real users have touched the app.
