Mobile Apps
Your app in the App Store and Google Play, built, shipped, and maintained.
From the work: Vulkanizer Grbić
a site with a 3D tyre
A tyre shop and wheel alignment service in Novi Sad. The hero is a 3D tyre in smoke, the rest of the site leads to the phone number and a booking.
We build mobile apps for iOS and Android and carry them from first sketch to a live listing in both stores. You get one team for design, development, App Store and Google Play submission, and the updates that keep the app running after launch. You hand us the problem and the goal. We return a working app and the account access to prove it is yours.
TIM Studio works from Novi Sad in Serbia, remotely, in English and Serbian, for companies in the UK, the EU and the US, and at home across Serbia, Croatia, Bosnia and Herzegovina and Montenegro.
What you get
A production iOS and Android app, published under your own Apple and Google developer accounts
A cross-platform build in React Native or Flutter, or fully native Swift and Kotlin when the case requires it
Complete App Store and Google Play listings: screenshots, descriptions, icons, age ratings, and privacy declarations
Backend and API integration, push notifications, in-app purchases, and analytics wired in and tested
Source code, build pipeline, and signing keys handed over with documentation, so nothing is locked to us
Crash reporting and a defined plan for OS updates, store policy changes, and version releases
How the work runs
Scope and flows
We map the core user flows, agree on the platforms and tech, and define exactly what version one ships with.
Design and build
We design the screens, build the app against a real backend, and review working builds with you on actual devices, not mockups.
Store submission
We prepare both listings, handle Apple and Google review, and resolve any rejections until the app is approved and live.
Launch and maintain
We monitor crashes and reviews after release and ship updates for new OS versions, bug fixes, and the features you add next.
Before you ask
Both. For most products we recommend React Native or Flutter, since one codebase serves iOS and Android and cuts cost and timeline. When an app needs heavy device features, demanding graphics, or platform-specific behavior, we build native in Swift and Kotlin. We decide with you during scoping based on the app, not a default.
Yes. We handle the full submission: store listings, screenshots, privacy and data forms, age ratings, and the Apple and Google review process. We publish under your own developer accounts so you own the app and the listings from day one. If a reviewer rejects the build, we fix the issue and resubmit until it is approved.
Apps are not finished at launch. Apple and Google release new OS versions, change store policies, and devices change. We offer maintenance that covers crash monitoring, bug fixes, OS compatibility updates, and new versions as you grow the app. You can also take the code and run it yourself, since we hand over the full source and signing keys.
