Mobile app development in London
We build iOS, Android and cross-platform apps for UK businesses from our team in Pakistan. Fintech, health and retail apps that clear App Store and Play review, respect UK GDPR, and move forward every day in the window your morning and our afternoon share.

Mobile App Development for London
London 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.
We work remotely from Pakistan, and there is no London office. What that changes is the rhythm of the work rather than the code. Pakistan is four hours ahead of the UK in summer and five in winter, so the builds your team tests in the morning reach us in our afternoon, while there is still working day left on both sides to act on the feedback. 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.
Builds on your phone, feedback the same day
Test builds go out through TestFlight and Google Play internal testing, so your team reviews the real app on their own devices rather than a screen recording. Feedback given in your morning reaches the engineer who wrote the code during our afternoon, and we arrange our working hours to overlap yours when a release is close.

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 the store accounts, signing keys and repositories held in your name rather than ours

What else we build in London
Mobile App Development in London: common questions
Where are you based, and how do we review builds together?
Yarqat is registered in Islamabad, Pakistan, and we work with UK clients remotely; there is no London office. Reviews happen on video with a live build on your own device, and between calls feedback goes into your issue tracker where the engineer who wrote the feature picks it up. The store accounts and signing keys are in your name throughout, so the app never depends on access to our machines.
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.
Mobile app development in London?
Tell us what you are building. We serve London remotely, with no local office and no account manager in between, so the person who reads this is the one who would run the work.
- 01A senior engineer reads it. Not a form queue, and not an account manager.
- 02We reply either with questions or with a straight answer that we are not the right fit.
- 03If it looks like a fit, a technical call with the person who would actually run the delivery.
- 04Then scope, effort and risk in writing, before anyone signs anything.
