04 / Factors

What factors affect the price of your app?

The cost of developing a mobile application depends on multiple variables. Understanding these factors will help you better define your project and optimize your investment.

UI/UX Design Complexity

A basic design with standard screens costs less than a custom interface with animations, micro-interactions, and a complete Design System. Design represents 15-25% of the total budget.

Required Features

Each feature adds complexity: social login, in-app payments, geolocation, real-time chat, segmented push notifications, or AI integration significantly increase the cost.

Backend & Database

An app with its own backend, custom API, and scalable database requires more development than one using services like Firebase or Supabase. Backend can represent 30-40% of the project.

Platforms (iOS, Android or both)

Developing for a single platform is more affordable. With cross-platform frameworks like React Native you can cover iOS and Android with just 20-30% extra cost.

Security & Compliance

Apps handling sensitive data (health, finance) require advanced encryption, 2FA authentication, and compliance with regulations like GDPR, which increases development costs.

Admin Panel

A basic CMS to manage content differs from an advanced dashboard with analytics, user management, content moderation, and integrated marketing tools.

06 / Frequently Asked Questions

Questions about app development costs

We answer the most common questions about budgets, timelines, and the mobile app development process.

It depends on scope. A simple app or an MVP runs from €8,000 to €25,000. A full product, with iOS and Android, backend, integrations and an admin panel, from €25,000 to €80,000. A platform with real time, AI or heavy scale, from €80,000 to €300,000. The average project in Spain is around €40,000. The exact figure comes out of the discovery: €2,000, credited in full against the project.
