Short answer: the app development companies in Argentina worth calling fall into three groups: boutiques and product studios (NaNLABS, 10Pines, 7iDeas, Atomix), mid-size firms (Flux IT, Vates, IT Oeste) and one global firm (Globant). The right one depends less on size than on who will maintain the app in its second year, because Apple and Google change their requirements every year and an app nobody updates eventually drops out of the stores.
Building a mobile app has one difference from any other software project that rarely shows up in rankings: it isn't finished when it's delivered. Apple and Google update their requirements every year. Google, for example, requires new apps and updates to target a recent Android API level, and that target moves forward every year. An app that nobody touches for eighteen months starts falling out of the stores.
That's why this guide doesn't sort companies by size or by number of projects. The question it tries to answer is who will still be there for you in year two.
Disclosure: Atomix, the publisher of this guide, is included in the list. It's described with the same criteria as everyone else, and you can discount it if you prefer.
How this list was put together
Four criteria you can check before signing anything:
- They publish to both stores. Shipping to the App Store and Google Play involves accounts, reviews and paperwork of their own. Having done it many times shows.
- They offer maintenance, not only the build.
- They're clear about native versus cross-platform, and explain why they recommend one.
- The apps they show are still live. This is the most useful filter and the easiest one: search the stores for the case studies on their site.
Each company below is described only with what it says about itself on its own site or in a public directory, linked next to it. Nothing here is a score.
The list at a glance
Company | Group | Where the description comes from | Fits best |
|---|---|---|---|
NaNLABS | Boutique / product studio | A new product that still needs defining | |
10Pines | Boutique | Apps that will live and grow for years | |
7iDeas (Siete Ideas) | Boutique | Apps tied to internal operations and integrations | |
Atomix | Boutique (publisher of this guide) | Apps connected to a company's own operations | |
Flux IT | Mid-size | Apps that are part of a larger digital product | |
Vates | Mid-size | Apps with formal QA and testing requirements | |
IT Oeste | Mid-size | Local companies that want a nearby vendor | |
Globant | Global | Mass-market apps with a corporate budget |
Boutiques and product studios
NaNLABS
A software studio from La Plata, founded in 2013 by four full-stack developers, according to its Sortlist profile. It works with startups and companies in the US on product design as well as development.
Who it's for: a new product where what to build still has to be worked out.
10Pines
A software development company with its main office in Buenos Aires, per its own site, which describes its work as custom software development.
Who it's for: applications that are going to live for years and keep growing in features.
7iDeas (Siete Ideas)
A software partner based in Tandil that describes its work as custom development, systems integration and AI agents for real operations, on its site.
Who it's for: an app that has to plug into how a company already operates.
Atomix
(Publisher of this guide.) Custom apps with scope and price fixed before work starts, focused on apps connected to a company's systems: orders, logistics, field sales, operations on the street. A project runs USD 5,000 to 10,000, and only exceptional, much larger projects go above that; a free working demo comes first, in 24 to 48 hours, and most projects reach production in under a month.
Who it's for: companies that need an app that talks to their operation, not a standalone app.
When not: consumer apps that need their own growth and monetization strategy.
More detail: app development at Atomix.
Mid-size firms
Flux IT
An Argentine company that builds digital products and solutions, per its site, with teams that combine design and development.
Who it's for: apps that are one piece of a bigger digital product.
Vates
Development and testing with a stated focus on QA. The Atlassian partner directory lists it as Vates Inc (an EPAM Company), with entities in the US and Latin America.
Who it's for: apps with formal testing requirements.
IT Oeste
A software factory that builds web, mobile and desktop systems, and describes itself on its site as having more than 50 employees and more than 10 years of experience.
Who it's for: companies in the Buenos Aires area that prefer a vendor close by.
Global firm
Globant
Founded in Argentina and now a global, publicly traded company (investor relations). It builds digital products for large organizations with teams at scale.
Who it's for: mass-market apps with a corporate budget.
When not: an internal app for your field sales team. That's a different category of service.
What this list doesn't decide, and decides the outcome more
Picking the right vendor matters less than these three decisions, which are yours.
Native or cross-platform. An app built with React Native or Flutter shares code between iOS and Android and costs considerably less. A native app makes better use of the hardware. For the vast majority of business apps, cross-platform is the right answer, and anyone pushing you to native without explaining why is making your project more expensive. We go deeper in how much mobile app development costs.
Whether you need an app at all. Many projects that start as an app are better solved with a responsive web app or a PWA: opened by link, nothing to install, no store review and instant updates. An app is justified when you need the camera, background GPS, push notifications or offline work.
Who owns the store accounts. The Apple and Google developer accounts have to be in your company's name, not the vendor's. If they're in the name of whoever built the app, your app is hostage to that relationship. It's one line in the contract, and it gets fixed at the start or never.
The cost that isn't in the quote
Recurring cost | Amount | Source |
|---|---|---|
Apple Developer Program | USD 99 per year | |
Google Play developer registration | USD 25, one time | |
Keeping the app working and in the stores (2026 market reference) | USD 1,500 to 4,000 per year | Updates for new OS versions and store requirements, with no new features |
A company that quotes the build without mentioning the yearly upkeep isn't necessarily being dishonest, but it's leaving a cost out of your math.
This list is based on public information as of October 2026 and on how each company describes itself. Check before you decide: this market has seen several recent acquisitions, and some rankings still list companies that are now part of another one.
Frequently asked questions
Which app development company in Argentina is best for a US company?
There isn't a single best one. Product studios fit a new product that still needs defining, mid-size firms fit apps inside a larger digital program, and global firms fit corporate-scale budgets. Check that the apps in their portfolio are still live in the stores and that they offer maintenance.
Should my app be native or cross-platform?
For most business apps, cross-platform with React Native or Flutter: one codebase for iOS and Android at a lower cost. Native makes sense when the app depends heavily on device hardware or performance.
Who should own the App Store and Google Play accounts?
Your company. If the developer accounts belong to the vendor, the vendor effectively controls your app. Put it in the contract before work starts.
How much does it cost to keep an app in the stores?
Apple charges USD 99 per year for its developer program and Google charges a one-time USD 25 registration. On top of that, as a 2026 market reference, plan for USD 1,500 to 4,000 a year to keep the app updated for new OS versions and store requirements.
Do I need an app or would a web app be enough?
If you don't need offline work, heavy use of the camera or GPS, reliable push notifications or daily frequent use, a responsive web app or a PWA is usually enough and costs less.
If you want to see your app as a working demo before deciding, book a call.
