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 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. Embedding without a city story is 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. 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.
