Mobile app development for UK / EU startups — studio in Sarajevo

Non-technical founders shortlisting a mobile app development company for startups usually need one partner from idea to App Store and Google Play — not a slide deck and a vanishing contractor. CodeLoop Studio in Sarajevo ships that path remotely for UK and EU teams: discovery, design for the first slice, build, store submission, then stay for v1.1 if usage proves the cut.

Mobile app development company for startups: design, development and launch

Mobile app development for startups fails when the first workshop is a forty-page spec and the second is silence. CodeLoop Studio in Sarajevo is a mobile app development company for UK and EU startups that need a path from idea to App Store and Google Play: freeze one loop, design for that slice, ship both stores when the product is mobile, then stay for OS updates if the cut works.

We work remotely in English. There is no Shoreditch office. London founders who already hire remotely across the EU are a fit; procurement that requires a UK Ltd on-site is not. A focused MVP often lands around three months when the slice is frozen; typical full products sit in a 3–9 month band. Written estimate within 24 hours via the online estimate.

Scope discipline lives on MVP development. Cost drivers without a bait banner: app development cost. Nearshore hours: nearshore for UK and EU. Founder notes: mobile apps for UK startups.

The path we actually run

01
Discovery
What must ship, who uses it, which stores. What is out of v0 is written down — that document is the product.
02
Design for the slice
Screens and flows for the first loop only. Not a redesign of email and six empty dashboards.
03
Development
Flutter, React Native, or native — picked after features. Iterations you can tap on a phone.
04
App Store and Google Play
Signing, listings, privacy labels, review notes. Launch support is in the plan.
05
After launch
OS and framework updates, crash triage, the deferred backlog. Or a clean handover if you staff in-house.

Studio path versus the other honest options

This page · idea to stores

One studio owns discovery through launch. Best when founders need a partner, not only a résumé in Slack.

MVP-only or staff-aug

Thin cut without store ownership → MVP development. Capacity inside your process → hire a dedicated team or staff augmentation.

What to freeze before the first build

One loop a stranger can finish
Search in one market, a QR menu, a measurement flow — not six roles.
Which stores and who owns the accounts
Apple and Google accounts must be yours before launch week.
What is explicitly out of v0
The deferred backlog is a deliverable. Without it, every call reopens scope.

Frequently asked

Shortlist studios that own discovery through store submission, publish real case studies, and will not invent a capital-city office. CodeLoop Studio in Sarajevo does that path for UK and EU startups: freeze one loop, build, ship both stores when mobile is the product, stay after launch. English, CET overlap. Estimate in 24 hours. We will not invent a “top 10 UK” list.

Yes. Remotely from Sarajevo with CET overlap for a normal UK workday. There is no London office and no Shoreditch mailbox. Visit if useful; it is not a listed address in your city. London-shaped delivery notes: /mobile-app-development-london.

MVP development is the cut and the first version. This page is the founder path: idea → stores → after launch, including non-technical buyers who need store ownership explained. Both pages link to each other; we will not cannibalise with two identical H1s.

A focused MVP often lands around three months when the slice is frozen. Typical full products take 3–9 months. Compressing calendar without cutting scope increases cost and risk.

A written range after features — not a bait package. Cost drivers: /app-development-cost. Send a brief via /online-estimate for a range within 24 hours.

Yes — that is legacy software takeover: code audit, freeze, continue. Path: /legacy-software-takeover.

We work remotely with London-based and other UK founders from our studio in Sarajevo. We have no London office: discovery, design, development and the App Store / Google Play launch run over video calls, Slack, Figma and your GitHub.

Yes. We turn the idea into a frozen first version with you — what ships, who uses it, which stores. You do not need a specification or a stack decision first; we recommend Flutter, React Native or native after we see the features.

Yes. One team covers discovery, UX/UI for the first slice, development, store listings and review submission, then updates after launch if usage proves the cut.

You do. Repositories, store accounts and signing credentials sit in your company's name; we work inside them.

Yes — Koliko, WoodMeter and cijene.me each started as one sharp job and shipped to the stores; each case study names the platform and our role. You can also check our profile on Clutch: https://clutch.co/profile/codeloop-studio .
