Mobile app & game development studio

We build mobile apps and games people love.

STR Code is a mobile development studio. We design, build and launch apps for iOS and Android, from the first sketch to the App Store and Google Play, and we stay with you long after release day.

What we do

Everything you need to ship a mobile product

Pick a single service or hand us the whole thing. Either way, you get a team that has done it many times before.

iOS apps

Native iPhone and iPad apps in Swift and SwiftUI. Fast, polished and built to Apple's Human Interface Guidelines.

Android apps

Native Android apps in Kotlin and Jetpack Compose that feel right on every device, from budget phones to foldables.

Cross-platform apps

One codebase for both stores with Flutter or React Native, when time to market and budget matter most.

Mobile games

Casual and mid-core games built with Unity: gameplay, art integration, monetization, analytics and live ops.

UI/UX design

Research, user flows, prototypes and pixel-perfect interfaces. Apps that look great and are a pleasure to use.

Launch & support

Store listings, review guidelines, releases, monitoring and updates. We publish your app and keep it growing.

Need more than the app itself? Backends, APIs, admin panels, payments and analytics. We build the whole stack around your product, so you deal with one team only.

Why STR Code

A studio you'll want to keep building with

STR Code is a mobile development studio based in Serbia, working with startups and established businesses around the world. We are engineers, designers and game developers who genuinely love what we do, and it shows in every app we ship.

Whether you are launching your first product or taking an existing business mobile, we will build it right, and build it to last.

Let's talk

  • Senior team

    Your product is built by experienced engineers and designers who have shipped many apps to both stores.

  • End-to-end delivery

    Strategy, design, development, QA, release and support under one roof. One team, one point of contact.

  • Transparent process

    Clear estimates, weekly demos and a shared backlog. You always know what's done, what's next and what it costs.

  • Quality you can feel

    Clean architecture, automated tests and attention to every transition. Apps that feel native because they are.

  • On time, on budget

    We scope honestly, plan carefully and deliver when we said we would.

  • Built to grow

    Scalable backends, analytics from day one and a roadmap for what comes after launch.

A clear process with no surprises. You see progress every week and always know what happens next.

    Short iterations with a working build on your phone every week, so there are no surprises at the end.
