Custom mobile application
development service.

After years dedicated to native app development, we have taken a step further by specializing in app development with Flutter, Google’s most advanced technology for creating cross-platform mobile applications. We create custom apps that reflect the unique vision of your business.

 

Specialized funcionalities for your app

Over the years, we have packaged various functionalities commonly needed in many applications, which you will likely require in the development of your app.

Social integration

Instagram, Twitter, LinkedIn... You name it! We integrate your application with the platforms you need to facilitate user acquisition and retention, helping you make the most of everything social networks have to offer.

Push notifications

No matter what type of app you want to develop, you'll likely need a notification system to stay connected with your users. We specialize in the solution provided by Google through its Firebase Cloud Messaging (FCM) service.

Purchases & secure payments

If your app allows users to purchase services or products, we integrate with online payment solutions like Stripe, PayPal, or Adyen, avoiding the complexity and cost of implementing a custom payment gateway.

Advanced analytics & tracking

Analyzing user behavior is vital for the proper functioning and success of an application. We offer you the possibility of knowing how they navigate through it and we help you select and save the most relevant information.

Maps & geolocation

The use of maps is essential in certain apps. We know how to work with maps, locations, and everything that entails, providing functionalities that enhance user interaction with their environment.

Image recognition & multimedia

We also have experience in more specific and complex developments such as image recognition, coupon and code scanning and processing, and streaming video/audio playback.

FAQ's

We evaluate each project individually. For apps that require maximum native performance, we develop specifically for each platform. For projects needing a presence on both iOS and Android, we can use cross-platform development to optimize costs and time.

The biggest advantage of Flutter is that a single development allows us to have applications for both Android and iOS (and in fact with Flutter 3, also for web and desktop!). This means being able to reduce both the cost and the development time and simplify the subsequent maintenance of any app by having a single source code for both platforms.

This is a recurring question and surely 5 or 6 years ago we would have answered possibly not. But both the evolution of the framework by Google and that of the devices and operating systems themselves means that today it is possible to develop an app with Flutter with a design and performance equal to that of a purely native application. There is no need to be afraid of choosing Flutter as a development tool since the advantages are much greater in 99% of projects.
 

 

Of course. We can fully manage the publications in both Google Play and the App Store or provide support in those parts where you need help.

The cost of developing an app in Barcelona depends on several factors, such as the complexity of the application, required functionalities, the platform (iOS, Android, or cross-platform), design, and delivery deadlines. In general, the price can range from €5,000 to over €50,000, depending on these factors.

For example:

  • Simple apps: A basic app with limited functionalities could cost between €5,000 and €15,000.
  • Medium complexity apps: Apps with additional features like database integration, push notifications, or social media integration can range from €15,000 to €30,000.
  • Complex apps: Apps with advanced functionalities like secure payments, geolocation, external system integration, or apps with high user load can exceed €30,000.
