# Custom mobile app development for London teams

If you searched for a studio to build a custom mobile app in London, you do not need another vendor with a Shoreditch coworking photo. You need a team that ships iOS and Android, speaks product English, and is on a call during UK working hours. CodeLoop Studio is based in Sarajevo and works with UK companies remotely — including product teams in London.

## For London teams. Not an agency in Shoreditch.

If you searched for a studio to build a custom mobile app in London, you do not need another vendor with a coworking photo. You need a team that ships iOS and Android, speaks product English, and is on a call during UK working hours. [Mobile app development for London teams](https://www.codeloop.ba/mobile-app-development-london) is that offer: CodeLoop Studio, based in **Sarajevo**, working with UK companies remotely — including product teams in London.

We will not rent a mailbox in EC2 and call it an office. We will not invent a UK limited company on the homepage. If your procurement requires an on-site London entity, say so on the first call and we will not waste it. Most London teams hire us because the work is remote-first anyway.

Bosnia is on Central European Time, typically **one hour ahead** of the UK. A 9:30am London stand-up is 10:30am for us. Written updates stay async so you are not waiting overnight. The general delivery page is [custom mobile app development](https://www.codeloop.ba/custom-mobile-app-development). Embedding without a city story is [remote mobile app developers](https://www.codeloop.ba/remote-mobile-app-developers). US overlap lives on the New York page.

## UK hours, UK listings, no invented limited company

Bosnia is on Central European Time, typically one hour ahead of the UK for most of the year. Kickoff, stand-ups, and review calls sit inside a normal London workday — not a 9pm Zoom. Specs, Figma, and GitHub stay in your tools. We take App Store review, privacy nutrition labels, and launch-week bugs seriously. We work inside your Apple Developer and Google Play orgs, including UK store listings. Signing stays yours.

Native Swift and Kotlin when the experience must feel platform-perfect. Flutter or React Native when one squad should ship both stores without doubling cost. Typical mobile projects run **3–9 months** from idea to launch; an MVP can ship faster when the first slice is honest. Senior mobile engineers, typically below a local London squad at the same seniority, same English you already use with distributed hires. You keep product ownership; we own build quality.

GDPR-aware delivery is discussed up front: data residency, subprocessors, and the DPA — not after legal chases us. We can join an existing iOS or Android repo: audit, then embed or take a workstream. We will not silently rewrite your app unless that is the brief. LipoDIETA is a health product on both stores with web and dashboard around it — shipped work, not a Shoreditch prop. If procurement needs an on-site London entity, we are the wrong vendor. Say so. Most London teams hire us because the work is remote-first anyway.

## What London product teams actually buy

UK-hour overlap

Kickoff, stand-ups, and review calls inside a normal London workday — not a 9pm Zoom.

Your store orgs

Apple Developer and Google Play, including UK listings. Privacy nutrition labels and launch-week bugs sit in the plan.

Native or one squad

Swift and Kotlin when the OS must feel first-party. Flutter or React Native when one squad should ship both stores without doubling cost.

GDPR before the DPA

Data residency, subprocessors, and the DPA discussed up front — not after legal chases us.

Cost without the theatre

Senior mobile engineers, typically below a local London squad at the same seniority. Same English you already use with distributed hires.

ET cousins

If the buying team sits in New York instead, use [mobile app development for New York teams](https://www.codeloop.ba/mobile-app-development-new-york). Same studio, different overlap window.

## Say these out loud before procurement copies a London address

* Do you have an office in London?  
No. Sarajevo studio. FAQ on this page says the same thing. We will not list a street we do not occupy.
* Can we work in your Apple and Google orgs?  
Yes. UK listings included. Signing stays yours.
* Is the work remote-first anyway?  
If yes, CET overlap is the advantage. If you need a UK entity on-site, we are the wrong vendor — say so.

## Frequently asked

No. We are a Sarajevo studio. If you need a vendor with a UK entity on-site, say so — we will not waste a discovery call. Most London teams hire us because the work is remote-first anyway.

CET is typically one hour ahead of the UK. A 9:30am London stand-up is 10:30am for us. Written updates stay async so you are not waiting overnight for every answer.

Yes. We audit, then embed or take a workstream. We will not silently rewrite your app unless that is the brief.
