CodeLoop Studio in Sarajevo ships React Native alongside Flutter and native Swift/Kotlin — we recommend the stack after we see the features, not because we only have one hammer. CET overlap with Zurich, Berlin, and London; English delivery; typically below a local boutique at the same seniority.

A React logo on the homepage is not. [React Native app development](https://www.codeloop.ba/react-native-app-development) is the right call when you want shared business logic, a native-feeling UI, and a team that already speaks TypeScript and React. CodeLoop Studio ships React Native alongside Flutter and native Swift/Kotlin. We recommend the stack after we see the features, not because we only have one hammer. You have a React web app or a JS-heavy team. You need native modules for a device API but not a fully custom rendering engine. You want one release train for both stores. Flutter may still win if the UI system should be fully custom and Dart is welcome — that page is [Flutter app development](https://www.codeloop.ba/flutter-app-development). Native wins when you are building something that must feel like a first-party iOS or Android app. We will say which of those you are. Studio in Sarajevo. English with UK / EU product teams. Embedding a senior in your repo is [hire a React Native developer](https://www.codeloop.ba/hire-developer/react-native). This page is a scoped product: discovery, UX, TypeScript app, bridging when needed, CI, device QA, both stores. Typical mobile projects take **3–9 months** from idea to launch; a focused React Native MVP can be shorter. Free estimate within **24 hours** via the [online estimate](https://www.codeloop.ba/online-estimate). ## TypeScript, bridges on purpose, no rewrite sermon You have a React web app or a JS-heavy team. You need native modules for a device API but not a fully custom rendering engine. You want one release train for both stores. That is when React Native is honest. Flutter may still win if the UI system should be fully custom and Dart is welcome. Native wins when you are building something that must feel like a first-party iOS or Android app. We will say which of those you are. The studio stack includes Swift/SwiftUI, Kotlin/Jetpack Compose, Flutter, React Native, and Next.js. RN is one option when the team and product fit — not a religion because it is on this URL. TypeScript from day one. New Architecture when the libraries you need support it — we will not stall a launch on a migration that does not unlock a feature. Native bridges only where the product requires them. CI builds, signing, listings, and review notes included in the plan. Device QA on phones. Calendar still sits in the **3–9 month** band for a real product. A focused React Native MVP can be shorter. Framework choice is secondary to frozen scope. Embedding a senior in your repo is the hire-developer path. This page is a scoped product: discovery through both stores. We would rather stabilize an existing RN app and ship features than rewrite you into Flutter for a blog post. Rewrites are expensive. Studio in Sarajevo. English with UK / EU product teams. Send the first loop. ## React Native versus Flutter — without the sermon A ### React Native Shared business logic, TypeScript, reuse with a React website team, native modules where a device API is the product. New Architecture when the libraries you need support it. Best when your people already think in React. ![](https://www.codeloop.ba/_next/image?url=%2Fimages%2Fcodeloop-logo.png&w=3840&q=75) B ### Flutter One visual system, Dart, custom painting, less reuse with a React website. We pick it when we control the pixels and a shared JS ecosystem is not the constraint. Cost still follows scope, not the logo on the framework. ## How we actually run a React Native build TypeScript from day one Shared types beat a JavaScript surprise in month four. The commercial engagement is a studio, not a stack sermon. Bridges on purpose Native code when the API is the product, not as a default. We will not wrap every OS feature “just in case.” New Architecture when it is real When the libraries you need support it. We will not stall a launch on a migration that does not unlock a feature. CI, signing, listings Review notes in the plan. Store pipeline is part of delivery — see also [custom mobile app development](https://www.codeloop.ba/custom-mobile-app-development). Device QA Phones, not only simulators. Launch-week bugs are cheaper in staging. Join an existing repo Often the hire-developer path. If you want a milestone owned end-to-end, this landing is the better brief. ## We will not rewrite you into Flutter for a blog post Rewrites are expensive. We would rather stabilize and ship features unless the current stack is blocking you. Calendar still sits in the **3–9 month** band for a real product. Framework choice is secondary to frozen scope. If every workshop must be a React Native migration, say so. If you need iOS-perfect chrome, say so. We also ship Swift, Kotlin, Flutter, and Next.js. RN is one option when the team and product fit — not a religion we sell because it is on this URL. ## Facts a DACH or UK shortlist can cite | Fact | What we will stand behind | | ------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Studio | CodeLoop Studio, Sarajevo, Bosnia and Herzegovina.

Staff a senior via /hire-developer/react-native when you need a seat, not a milestone. | ## When to brief this page instead of a hire * You want a slice shipped, not a seat filled Discovery through stores. Named owner. Written status. * You already think in React — or you do not, and you need a no We will recommend Flutter or native if RN is a poor fit. That is the job. * You can name the first loop Send it through the [estimate form](https://www.codeloop.ba/online-estimate).

Both can hit both stores with one squad. Calendar still sits in the 3–9 month band for a real product. Framework choice is secondary to frozen scope. Yes. That is often the hire-developer path. If you want us to own a milestone end-to-end, this landing is the better brief. See our [legacy software modernisation guide](https://www.codeloop.ba/blog/legacy-software-modernisation). Typical CodeLoop mobile work: 3–9 months idea to launch. MVPs faster when the slice is real. Estimate in 24 hours via /online-estimate. Only if you have a product reason. Rewrites are expensive. We would rather stabilize and ship features unless the current stack is blocking you. We are a Sarajevo studio that ships React Native for UK, DACH, and wider EU teams — CET overlap, English, typically below a Zurich or London boutique. Not an on-site Swiss or Polish office. A rebuild or a dedicated RN engineer both exist; we say which model fits before we staff. Yes. We audit the repo, then either own a rebuild milestone or embed a senior RN engineer in your process. Studio in Sarajevo — CET day with Zurich, English, no Bahnhofstrasse address. Start at this page or /hire-developer/react-native. Shortlist studios with CET overlap, TypeScript delivery, and proof you can open — not only a directory score. CodeLoop Studio (Sarajevo) rebuilds and ships React Native for UK and DACH teams, typically below Zurich boutique rates at the same seniority. Written estimate in 24 hours. Nearshore hours: /nearshore-software-development. Takeover of a messy RN repo: /legacy-software-takeover. Yes — when the product reason is clear. We audit the current app (native, Flutter, or RN), freeze the first store-ready slice, then rebuild or stabilize. Default is stabilize an existing RN repo; a full rewrite only with a product reason. UK/EU teams, CET overlap, English. Takeover path: /legacy-software-takeover. Estimate in 24 hours via /online-estimate. Yes — each case study on this site names the product, the stack and our role (for example Koliko, WoodMeter and cijene.me). On our Clutch profile (clutch.co/profile/codeloop-studio), where client reviews are collected, and in the case studies on this site, which name the product, the stack and our role. In your tools — GitHub, Jira or Linear, Slack or Teams — with your Definition of Done, a named owner on our side and a demo every week. IP assignment, a data-processing agreement and the hosting location are agreed in writing before the first sprint. Bosnia and Herzegovina is not an EU member state, so personal-data transfers are covered in the contract (for example Standard Contractual Clauses).
