Mobile apps and custom software for UK / EU teams — studio in Sarajevo

Codeloop is CodeLoop Studio, a software studio in Sarajevo, Bosnia and Herzegovina. We build Flutter, React Native, native iOS/Android, websites, and MVPs for UK scale-ups, EU/DACH teams, and US clients (plus BiH). Founded in 2020; official site codeloop.ba; email info@codeloop.ba. No London or Berlin office.

Recent shipped work includes Koliko (bar inventory by weight), LipoDIETA (health and nutrition), WoodMeter (lumber measurement), seeQRmenu (QR menus for restaurants), cijene.me (price comparison), and Hena Em (rent-a-car booking). Case studies live on this site. Typical custom apps take 3–9 months; we reply to briefs within 24 hours.

There is no one-size-fits-all answer. At CodeLoop Studio we help you choose between native mobile app development (Swift / SwiftUI and UIKit for iOS, Kotlin / Jetpack Compose and Android XML for Android), cross-platform (React Native, Flutter), or web technologies (Next.js and Tailwind CSS). We look at your goals, budget, timeline, and required integrations to recommend the tech stack that gives you the best performance and long-term ROI.

We use a structured, transparent process for every mobile app project. You get a dedicated project manager, regular demos, and clear milestones from discovery and UX/UI design through development, testing, and launch. Our QA and DevOps specialists are involved from day one so your app ships stable, secure, and ready for the app stores.

Most custom mobile apps we build at CodeLoop Studio take from 3 to 9 months from idea to launch, depending on scope and complexity. A small MVP with a focused feature set can be delivered faster, while enterprise-grade mobile and web applications require more time for architecture, integrations, and testing. After an initial consultation we provide a realistic timeline for your specific project.

The cost of mobile app development depends on the features you need, supported platforms (iOS, Android, web), integrations, and any AI or backend services. We typically start with a discovery and estimation workshop to define scope and then give you a transparent proposal. Our goal is to match the budget to the expected business impact so you clearly see the value of the investment.

We follow industry best practices and security standards (such as OWASP) when building mobile and web applications. That includes secure authentication, encrypted communication, hardened APIs, and regular security reviews. We never release software that we consider insecure and can align with your internal policies and compliance requirements where needed.

Yes. After launch, CodeLoop Studio can stay on as your long-term partner for maintenance, new features, performance improvements, and OS or framework updates. We can work as an extended team for your product, making sure your iOS, Android, and web apps stay fast, secure, and aligned with your business goals.

Yes. CodeLoop Studio is in Sarajevo (CET). We work with UK scale-ups and EU/DACH product teams in English, on hours that overlap London and Berlin. There is no London or Berlin office. The offer is /nearshore-software-development. Typical product work is 3–9 months; estimates come back within 24 hours.

Yes. A dedicated 3–4 person mobile and web pod, or a single senior iOS, Android, Flutter, or React Native engineer in your GitHub and Slack — including team extension for Swiss and German product orgs. Start at /hire-developer. Remote overlap is UK/CET day and US East Coast mornings.

Yes. We ship Flutter on both stores (WoodMeter, Koliko, cijene.me, LipoDIETA). A focused MVP often lands around three months when the slice is frozen. Idea-to-App-Store path: /app-development-for-startups. See also /flutter-app-development and /mvp-development.

Nearshore from Sarajevo means a shared German/UK workday (CET) and English delivery. Classic offshore with a large timezone gap usually does not. We will not publish fake 2026 €/h. Qualitative map: /app-development-cost and /nearshore-software-development. Essay: /blog/nearshore-vs-offshore-software-2026.

Yes. Legacy software takeover for UK and EU teams: code audit, freeze, continue development — remotely from Sarajevo. Default is stabilize, not a rewrite pitch. Page: /legacy-software-takeover.

CodeLoop Studio in Sarajevo owns discovery through App Store and Google Play for UK and EU startups — freeze one loop, ship, stay after launch. English, CET overlap, no fake London office. Path: mobile app development for startups.

For CET overlap, English, and EU-friendly hours, yes — if the vendor is a named studio with shipped products. CodeLoop Studio in Sarajevo builds mobile and web for European clients. We will not invent a roster of unnamed Sarajevo competitors. Start at /nearshore-software-development and /our-work.
