WEB AND MOBILE APPLICATIONS
Custom applications for web, mobile and cross-platform use
We build the application your team or your customers use every day, with the flows, permissions and integrations it actually needs.
What changes when the application is built for you
Custom application development starts from the real journeys of the people using the product: which task it solves, with what data, on which device and under which permissions. That foundation shapes the interface, the backend, the integrations and how the product is released and maintained over time.
Choosing between web, mobile or cross-platform depends on context: office-based work, field work with camera and location, or customers who switch between devices. We design the journey first and the technology second, so the platform never forces a workflow that does not fit daily use.
Every application connects to your ERP, CRM, payment gateway or identity provider, and we agree which system owns each piece of data before writing any code. That decision avoids duplicated records and improvised technical choices once development is underway.
Our teams work from Barcelona and Madrid, and remotely across Spain, Europe, LATAM and the US. Custom application development ends with the product in production, with code, repositories and documentation under your company's control, free of licences that tie you to us.
STARTING POINT
Why many custom applications fail
The technology is rarely the problem. The gap between what was requested, what was built and how people actually work usually is.
A broken process, digitised
Rebuilding a process as-is, with all its exceptions and manual steps, only automates the mess. The result is an app that was quick to build but nobody wants to use three months later.
Data in two places
Without deciding which system owns each field, the application and the ERP end up disagreeing. Every mismatch forces someone to check manually which version is actually correct.
Nobody owns it
An app with no owner and no roadmap becomes obsolete as soon as the business shifts. The first symptoms are bugs nobody fixes and users going back to spreadsheets.
HOW WE WORK
From user journeys to an application in production
We sequence the work so the first release is usable and later releases do not force a rebuild of the foundations.
Understand real use
We map roles, frequent tasks, permissions and the actual context: office, field or end customer. That picture stops us designing screens for a use case that never happens in practice.
Design the flows
We prototype the key screens to validate the journey before investing in development. This surfaces friction and unnecessary steps while they are still cheap to fix.
Build and integrate
We deliver interface, backend and integrations with your systems, testing the cases that hurt most. We prioritise the scenarios where a failure would hit the business or the users hardest.
Release and evolve
We deploy, measure real usage and prioritise the next improvements with evidence rather than assumptions. The backlog gets reshaped by what the application reveals once real users are on it.
WHAT YOU GET
What a custom application project leaves you with
More than an executable: a working application plus everything needed to govern it.
Application in production
Web, mobile or cross-platform, released and ready for real users. It ships with basic monitoring in place to catch errors from day one.
Live integrations
Connections to ERP, CRM, identity or payments, documented and monitored. Each integration states which system owns the data to prevent future conflicts.
Code and repositories
Source, history and design assets in your hands, with no hidden dependencies. You can audit them, extend them or hand them to another team whenever you choose.
Evolution plan
A prioritised backlog and criteria for deciding what to build in the next phase. It gives you a clear rationale for why some improvements come before others.
EXPERIENCE
Applications already running every day
We have built digital products since 2008 from Barcelona and Madrid, with remote teams and experience in environments subject to Spanish ENS requirements.
- Web, mobile or cross-platform chosen by real usage, not by trend.
- Integration with ERP, CRM, payments or corporate identity from the first design.
- Store or in-house publishing with monitoring from day one.
- Code, repositories and documentation under your company's control.
