What's included

An app designed to grow your business

We don't just design pretty apps. We design them so your users come back, sign up and buy. Here's what your new app includes.

iOS + Android

A single codebase that runs on both platforms. The same cost as a single app, with twice the reach.

Custom UI/UX design

An interface built for your users. Every screen designed to guide the action you want them to take.

Push notifications

Direct communication with your users. Up to 90% open rates — far more than email.

Admin panel

A web back office to manage users, content, products and metrics. All from your browser, without touching the app.

Built-in analytics

See how many people use your app, which screens they visit and what they do. Real data to improve the product.

Publishing included

We handle the entire process on the App Store and Google Play: accounts, store listings, screenshots and app review.

Also included

Integrations with your business

We connect your app to what you already use: payment gateways (Stripe, PayPal, Bizum – Spain's mobile payment system), CRM, ERP, email marketing, maps, social login, biometric authentication. Your app isn't an island — it fits into your ecosystem.

Examples

How we work

From idea to the App Store in 4 steps

A structured, transparent process, with your sign-off at every stage.

01

Kick-off meeting

We talk through your idea, your users and your business model. You get a fixed-price quote and a realistic timeline.

02

UI/UX design

We show you every screen in a clickable prototype before we write any code. You approve the design before we move on.

03

Development

We build the app for iOS and Android and integrate the backend and admin panel. We show you progress every week.

04

Publishing

We submit the app to the App Store and Google Play. We manage the developer accounts and the entire review process.

Why us

Why choose our mobile app development company

We've been building custom software for more than 12 years. We're not specialists in one kind of app — we're specialists in making software work for your business.

iOS and Android, one project

We build with cross-platform technology (React Native / Flutter). The same cost, twice the reach. And near-native performance.

In-house team in Spain

Designers and developers on staff in Murcia and Madrid. No middlemen: you talk to the people building your app.

Fixed timeline and fixed price

The initial quote is the final price. And the delivery date is firm. No variable line items or extras halfway through the project.

Direct communication

A single point of contact throughout the project. We reply quickly and without unnecessary jargon.

Team

The people behind your app

Designers, developers and specialists working in-house at our offices in Murcia and Madrid (Spain). No middlemen: you talk directly to the people who design and build your project.

FAQ

Frequently asked questions

How much does it cost to develop an app?

The price depends on the scope: number of screens, features, integrations with your systems and technical complexity. We analyze your case, propose the scope you really need and send you a fixed-price quote, with no obligation.

How long until my app is ready?

A simple app can be published in 3–4 weeks and an MVP in 6 weeks. An app with standard features is delivered in 6–8 weeks, and more complex projects in 10–12. After the kick-off meeting we give you a fixed deadline, and we meet it.

Do you build apps for iOS, Android or both?

Both at once. We use cross-platform technology (React Native / Flutter) that lets us produce an iOS app and an Android app from the same codebase. The same cost as one app, with twice the reach.

Are there mandatory monthly fees?

No. Development is a one-off payment and the app is yours. You'll need Apple and Google developer accounts, under their current terms. If you later want maintenance and support or new features, we'll quote it separately.

What if I need changes after launch?

For the first few months after launch we support you free of charge to answer questions, fix bugs and make small adjustments. If you later need new features or a redesign, we'll quote it with no obligation. We never leave you on your own after launch.

How do you ensure project quality?

We work in milestones with continuous validation. We don't start coding until you're 100% happy with the design prototype, and during development we show you progress every week so you can approve it before we move to the next phase.
