Mobile apps that thousands of people use every day
We design, build and operate iOS and Android applications in Flutter — with their backend, their infrastructure and the support that comes after. One codebase, two stores.

The hard part of an app is not the screen
It is what happens behind it: the hardware, the payments, the identity and what occurs when there is no signal. We have shipped all of this to production.
Field work
Dynamic forms that adapt to each case, with photo and video evidence, and automatic delivery as soon as the device is back online.
Identity and biometrics
Sign-up validated against the data the organization already holds, biometric login and credentials stored securely on the device.
Payments and balance
Integration with local and international payment gateways, prepaid balance, full or partial refunds, and reconciliation against the admin panel.
QR and access control
Codes generated and validated in real time, with a trace of who used them and when.
Background geolocation
Automatic entry and exit logging based on location, without the person having to open the app.
Hardware over Bluetooth
Communication with physical equipment from the phone, to enable it, control it or read its status.
Push notifications
Reminders, operational alerts and institutional announcements, with a history inside the app.
Over-the-air updates
Fixes that reach the phone without waiting for store review.
Observability and SRE
End-to-end traces and metrics, error tracking on real devices, and on-call coverage for the infrastructure.
Nine apps, nine different problems

Mi SUPA
App for port stevedores: it digitalizes the pre-operational machinery check before each shift, with dynamic forms per machine type and photo and video evidence. Workers mark their availability, apply to shifts, track their wages and manage their documents, with biometric login.

From the idea to the stores
01
We understand the problem
We start from the real operation: who uses the app, in what context and which systems it has to talk to.
02
We build in small steps
Short, reviewable deliveries. You see the app running on your own phone from the first weeks.
03
We ship to the stores
We handle the App Store and Google Play: accounts, listings, reviews and updates.
04
We operate it with you
Monitoring, error tracking on real devices and fixes that land without waiting for store review.
Flutter up front, whatever it takes behind
A single codebase for iOS and Android, and the backend the project actually needs. These are the technologies we work with every day.

Your data stays yours
Sensitive information is kept isolated and protected. It's never mixed with other clients' data.
You start with low risk
We begin with a scoped prototype at a fixed price. You see results before investing big.
You never pay twice
Everything we build at each stage is reused in the next. The work accumulates instead of repeating.
Behind every project is an engineering cooperative from Rosario, Argentina, with over 10 years building custom software and more than 80 projects delivered.
