App development in Mayfair
Your app needs to work under real load, pass App Store and Play Store review, and keep working after launch. We build mobile applications for the offices around Curzon Street and Berkeley Square—firms where sign-off matters and maintenance is the real work.
App development for Mayfair businesses
Hubb Group is a digital agency and software company. Our studio is in Dubai and we work with UK clients remotely, on UK hours, with a named lead on every project. Contracts and invoices are issued by our UAE company, in pounds.
We measure what matters: crash rates, session retention, task completion, feature adoption. You'll see which users stay and why. Monthly reports show load patterns, common errors and opportunities to iterate. Numbers your board understands—no guessing.
Every project is a fixed quote with a clear timeline and clear milestones. You own the work and the accounts outright when we're done — no lock-in, and nothing you can't take with you.

Apps that pass review and stay useful
Building an app for regulated business means thinking ahead. App Store review isn't a surprise—it's a checkpoint we plan for. We scope tight to hit your runway. We test offline behaviour so your app works when the network doesn't. We document accessibility from the start because it's the right thing and because it stops review delays. Then we stay involved after launch, because that's when you learn what users actually need.
Your backend matters as much as the frontend. We build for load, for security, for the integrations you depend on. If your users work with sensitive data or compliance-heavy processes, we architect from that constraint, not around it. The app lives inside how your business operates. It doesn't fight your approval chains.
Native or cross-platform: depends on your users
Some apps need the full power of iOS or Android. Some teams need to reach both platforms without building twice. We help you pick based on who uses it and what they need to do—not based on what's trendy. Your runway, your user base, your technical team's size: those drive the call. We build either way.
The choice isn't permanent. If you start cross-platform and later need native speed on one platform, we build it. If you start native and need to reach more users, we expand. The structure sits underneath, ready for what comes next.
Approval, compliance and restraint in the interface
Mayfair buyers don't respond to flash. They respond to rigour. Your app's interface speaks in restraint—clean, purposeful, no noise. Every screen has a job. Every interaction earns its place. The design passes muster with people who've seen everything and trust almost nothing. That builds confidence faster than any animation.
Compliance lives in the work from day one, not bolted on at the end. Data governance, permission flows, audit trails—we build these in. Your sign-off team sees a system they understand. Handover to ongoing support is clean because the foundations are sound.
After launch: support, iteration and data you can trust
Your first users tell you what breaks. Logs tell you where load sits. Support tickets tell you what confuses people. We track these signals and iterate. We stay on retainer so fixes happen fast and features land when they matter. Your app stays useful because someone's watching.
Measurement is straightforward: crash rates, session length, task completion, feature adoption. We report what you can act on. Your board sees numbers that justify the investment, not vanity metrics. Retention data shows which users stick around and why.
App development in Mayfair — common questions
How long does the approval process take with App Store and Play Store?
Review timelines vary. We scope work to pass review first time, then pad the timeline for resubmission if needed. Compliance-heavy apps need more careful submission. We plan for this and communicate delays early.
Do you build apps that integrate with Bloomberg, SWIFT or other trading systems?
We integrate with the systems you use. APIs, feeds, data pipelines—we handle backend work that talks to your existing infrastructure. If security or regulatory requirements are strict, we build around those constraints from the start.
What happens if the app needs changes after we go live?
We stay involved. Retainer support covers bug fixes, minor updates and user help. Larger changes are scoped separately. This keeps your app stable and lets you add features as your users actually need them.
Can you build an MVP that works for internal testing before we commit to the full release?
Yes. We scope tight MVPs for testing and learning. Your team uses it, you see what works, we adjust before full launch. This saves money and gets you real feedback fast.
How do you handle sensitive data and compliance obligations in the app?
Data governance sits in the architecture, not the UI. We build encryption, permission flows, audit trails and access logs. Your compliance officer sees a system designed for oversight from the ground up.
What if we outgrow the first app and need something bigger?
The foundation scales. If you start with a focused MVP and need to expand, we've built the backend to handle it. Larger feature sets, more users, more platforms—the structure is ready.
