Custom mobile app development for New York teams

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. 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.

For New York teams. 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 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. Embedding a senior is hire a developer. Send a brief through the 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.
