App development in Clerkenwell
You work in a field where every detail is assessed by someone who does this for a living. Your app needs the same standard. We build mobile applications that pass review, work offline, and integrate with the systems you already run.
App development for Clerkenwell 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 app success in usage: daily active users, session duration, feature adoption, crash rates, uninstall velocity. For regulated sectors, we track audit trails and compliance logging. For design practices, we report team adoption and iteration cycles. You see whether the app justified the cost in real user behaviour, not in promises.
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.

Everything we deliver includes
Scoped to ship
A first version people will actually open, priced before the build starts.
Store review handled
App Store and Play requirements — privacy, account deletion, demo logins — dealt with.
Works on a bad connection
Offline behaviour and accessibility treated as requirements, not polish.
Fixed prices
A clear quote and timeline up front — no open-ended retainers, no surprises.
A named lead
One person who knows the build, on UK hours, not a ticket queue.
Yours to own
Code, signing keys and store listings in your name.
An app that passes review and stays live
App Store and Play Store review stops weak work before launch. We scope tightly to what your first users actually need, build with accessibility and data handling that reviewers check for, and document the decisions so you're not scrambling when review feedback lands. Most apps that fail don't need more features—they need clearer scope.
After launch, your app needs maintenance. We stay involved: handling OS updates, monitoring crashes, fixing real-world bugs that staging never showed you, and iterating based on what your users do. This is the work that keeps an app useful.
Backend and offline thinking from the start
A mobile app that only works online is not an app—it's a portal. We architect backends that sync when the network returns, cache what matters offline, and keep your data secure without slowing users down. This matters in regulated work, where connectivity is unreliable and users need to keep moving.
Your systems don't exist in isolation. We integrate with the tools you already use: CRMs, databases, payment processors, compliance platforms. The integration happens in code, not through manual steps. Your team sees a working app, not a bridge to solve.
Native or cross-platform: what your users need
Native apps feel native. Cross-platform apps reach more people on the same budget. The choice depends on who you're building for and how long your runway is. We assess both and recommend based on your users and your constraints, not our tooling preference.
Clerkenwell practices rarely want to be early adopters of every platform. We build for the devices and OS versions your actual users run, not for the margins in an architecture choice. That narrows scope and improves craft.
How we measure what works
Your app's success shows in usage metrics: daily active users, session length, feature adoption, crash rates, and how long users keep it installed. We track these from day one and flag what's working and what's not. You know whether your app justifies the build cost.
For regulated sectors, we log everything: user actions, data changes, system errors, compliance checks. Auditors can trace a decision to the code. For design and architecture practices, we report on adoption across your team and help refine based on what actually gets used.
App development in Clerkenwell — common questions
How do you handle App Store review when compliance matters?
We build with review requirements embedded. Consent flows, data handling, privacy disclosures, accessibility features—these are part of the scope, not added last. We've seen the review feedback patterns. We avoid them.
What happens if my users are offline?
The app queues their actions and syncs when the network returns. Critical data downloads to the device beforehand. They can keep working. This is non-negotiable for field teams, compliance workflows, and anywhere connectivity drops.
Do you work with practices where technical standards are set by the clients, not by us?
Yes. That's actually our default. Your sector's reputation is built on craft and rigour. We meet that standard in code. You know the work will hold up because you can read it.
Can the app integrate with systems we already run?
Yes. We've integrated with enterprise CRMs, payment platforms, document systems, and custom backends. Integration happens in the app layer. Your existing tools keep working, and your users see one interface.
What's the difference between a tight MVP and a half-baked app?
An MVP solves one problem well and passes review. Half-baked tries to do everything and fails review. We scope ruthlessly: what's the first thing users need to see if it works? That's the scope. Everything else ships later.
Do you still support the app after it launches?
We maintain it. OS updates, crash fixes, performance tuning, bug resolution. Most app failure happens after launch, not before. We treat maintenance as part of the job, not as something that ends.
