Mobile app development in London
A London-registered team building iOS, Android and cross-platform apps for UK businesses. Fintech, health and retail apps that clear App Store and Play review, respect GDPR, and iterate at the pace of everyone being in the same timezone.

Mobile App Development for London
London is our home market, and its mobile work has a particular shape. Fintech and neobanking, health apps that handle sensitive records, retail and loyalty, and enterprise tools for large UK organisations. What these have in common is scrutiny. The store reviewers, the regulators and the users all expect more of an app that moves money or holds health data, and getting it wrong is expensive in ways a slower category would forgive.
A lot of that scrutiny lands at the two gates most teams underestimate: store review and data protection. Apple and Google both reject on rules that are easy to trip over, from account-deletion requirements to payment-mechanism rules to privacy-label accuracy, and a rejected build can cost a launch window. GDPR and the UK data-protection regime shape what you can collect, how you ask, and how you store it. We build with both in mind from the start, because a submission or a privacy design fixed under deadline pressure is the worst time to discover the rules.
Being London-based changes the working relationship rather than the code. Same timezone means iteration happens in real time instead of by overnight handoff, contracts sit under English law and invoices in sterling, and when a decision genuinely needs everyone in one room we can hold a workshop in person rather than scheduling around a flight. The engineer on your first call is the one who runs the delivery, which is the whole point of working with us rather than an agency that pitches senior and staffs junior.

What is specific
Built for London
App Store and Play compliance done first
Store rejections cost launches. We build against Apple and Google review guidelines from the start, covering account deletion, payment rules, privacy labels and permissions, so submission is a step rather than a scramble. For fintech and health apps, where the rules bite hardest, that discipline is the difference between a clean release and a slipped date.
GDPR and UK data protection by design
What you collect, how you ask and how you store it are design decisions, not a policy written afterwards. We build data protection into the app from the outset, which matters most for the fintech and health products that make up so much of London mobile, where a privacy afterthought is both a legal and a reputational risk.
Same timezone, in the room when it helps
Being London-based means iteration happens live rather than by overnight handoff, and when a decision genuinely benefits from a room, an in-person workshop is a train rather than a flight. Contracts under English law and invoices in sterling remove the friction an overseas partner brings whether or not anyone mentions it.

Scope
What we build
Project delivery, owned end to end, for London clients.
- Native iOS and Android apps, or a single cross-platform Flutter or React Native build where that suits the product and roadmap
- App Store and Google Play submission built against current review guidelines, including account deletion, payment rules and accurate privacy labels
- GDPR and UK data-protection-aware design covering consent, data minimisation and secure storage from the first screen
- Secure authentication and in-app payments, with the compliance that fintech and health products demand handled as architecture
- Push notifications, deep links and analytics wired to your backend, with offline handling where the product needs it
- A release and CI pipeline your team can run, with senior engineers available for in-person workshops when a decision needs a room
Mobile App Development in London: common questions
Where are you based, and can we meet in person?
Yarqat is registered in London and it is our home market, so yes. Most delivery is better done remotely and we default to it, but when a decision genuinely benefits from everyone in one place, an in-person workshop is straightforward to arrange. Same timezone also means day-to-day iteration happens live rather than by overnight handoff.
Can you get our app through App Store and Play review?
Yes, and we build for it from the start rather than treating submission as a final hurdle. We design against current Apple and Google guidelines, covering account deletion, payment-mechanism rules, privacy labels and permissions. For fintech and health apps, where reviewers scrutinise hardest, that groundwork is what keeps a launch date from slipping on a rejection.
How do you handle GDPR and UK data protection in a mobile app?
As design decisions taken early. What the app collects, how it asks for consent and how it stores data are built in from the outset, not bolted on as a policy afterwards. This matters most for the fintech and health products common in London, where a privacy afterthought is both a legal and a reputational exposure.
Native or cross-platform for a UK launch?
It depends on the product. For most apps a single Flutter or React Native codebase covers iOS and Android efficiently with no meaningful compromise. Where a product depends on platform-specific capability or peak performance, native is the right choice. We recommend based on your product and roadmap, and the engineer making that call is the one who builds it.
Who builds the app, the person we first speak to or someone else?
The person you speak to first. We are deliberately small and senior, so the engineer who scopes your app is the one who runs the delivery. That is the opposite of the agency pattern where a senior team wins the pitch and a junior bench does the work, and it is why estimates and reality stay close.

A technical conversation with the engineers who would do the work. If we are not the right fit, we will say so on the call.
