You need a team that ships iOS and Android, speaks product English, and shows up on an ET morning call. CodeLoop Studio is based in Sarajevo and works with US companies remotely — including product teams in New York. No Fifth Avenue address. Overlap hours and store-ready delivery instead.

Not an agency on Fifth Avenue. If you searched for a studio to make a custom mobile app in New York, you do not need another vendor with a Manhattan coworking photo. You need a team that ships iOS and Android, speaks product English, and shows up on an ET morning call. [Mobile app development for New York teams](https://www.codeloop.ba/mobile-app-development-new-york) is that offer: CodeLoop Studio, based in **Sarajevo**, working with US companies remotely — including product teams in New York. No Fifth Avenue address. We will not list a New York street we do not occupy. If procurement requires a vendor with a US entity on-site in New York, say so on the first mail — we will not waste a discovery call. Most NY teams hire us because the work is remote-first anyway. Kickoff and stand-ups overlap when New York is starting the day. The rest is written: tickets, recordings, status you can read before standup. You are not waiting overnight for every answer. The delivery page without a city story is [custom mobile app development](https://www.codeloop.ba/custom-mobile-app-development). Embedding a senior is [hire a developer](https://www.codeloop.ba/hire-developer). Send a brief through the [online estimate](https://www.codeloop.ba/online-estimate) if you want a scoped reply within **24 hours**. ## ET mornings. Your orgs. No Midtown mailbox. A named owner, weekly demos when New York is starting the day, and an app that can survive App Store review, privacy nutrition labels, and launch-week bugs. We build inside your Apple and Google orgs, your Figma, and your GitHub. Native or cross-platform is a product decision after we see the features — not a slogan on a SoHo landing page. Cost is typically below a local NYC squad with comparable seniority. Communication is the same English you already use with distributed hires. Startups and in-house product teams that already work Slack-first fit this model. Fintech, health, and unannounced products are normal; NDAs are standard. The rest of the US day is written: tickets, recordings, status you can read before standup. You are not waiting overnight for every answer. Typical custom apps take **three to nine months**; a thin MVP can be faster when scope is frozen. You keep product ownership; we own build quality and store submission support. Vellum is a reading-tracker we designed and built for iOS and Android — habits, library, progress. It is not a local-office prop; it is shipped work. We can join an existing iOS repo: audit, then embed or take a workstream. We will not silently rewrite unless that is the brief. If procurement requires a vendor with a US entity on-site in New York, we are the wrong vendor. We say it here. No Fifth Avenue address. ## What a New York product org actually needs from Sarajevo ET morning overlap Live conversation when the East Coast is starting the day. Async for the rest so you are not blocked on a six-hour gap. Your Apple and Google orgs US store accounts, privacy nutrition labels, launch-week bugs. Signing stays yours. NDA-ready Fintech, health, unannounced products. Standard. We treat confidentiality as the default, not an upsell. Stack after features Native or cross-platform is a product decision — not a slogan on a SoHo landing page. Cost without Midtown theatre Typically below a local NYC squad with comparable seniority. Communication is the same English you already use with distributed hires. Join an existing repo We audit, then embed or take a workstream. We will not silently rewrite your app unless that is the brief. ## Eastern Time mornings, your tools, no theatre 1. 01 ### Brief and overlap commitment What must ship, which stores, whether we can commit the ET window. Written in the estimate. 2. 02 ### Work in your systems GitHub, Figma, Slack. You keep product ownership. We own build quality and store submission support. 3. 03 ### Build on a real calendar Typical custom apps take **three to nine months**. A thin MVP can be faster when scope is frozen. 4. 04 ### Stores Inside your orgs. Review is a phase. Then the backlog if you want us to stay. ![](https://www.codeloop.ba/_next/image?url=%2Fimages%2Fcodeloop-logo.png&w=3840&q=75) Case study Vellum A reading-tracker for iOS and Android — habits, library, progress.
