## How it is calculated

It starts from 80 hours for a minimal app of up to 5 screens and adds 12 hours per additional screen. Login and user accounts add 40 hours, payments and subscriptions 60, a custom backend and API 80, push notifications 20, each external integration 25, custom design 60 and AI features 70.

The total is multiplied by platform: 0.75 for a single store, 1 for a shared codebase across iOS and Android, and 1.7 for two separate native apps.

The price range applies a market rate of €45 to €75 per hour, the usual band for studios and agencies in Spain. The timeline assumes one full-time person at 35 effective hours per week, with a three-week minimum.

Store fees ($99 a year on Apple, $25 once on Google), hosting and ongoing maintenance are not included. Maintenance usually runs 15% to 20% of the initial cost per year.

## Frequently asked questions

### How much does a simple app cost in Spain?

An app with 5 or 6 screens, login and notifications, sharing one codebase across iOS and Android, works out at around 140 development hours. At market rates that is €6,000 to €10,000, delivered in 4 to 5 weeks.

### Why do some quotes reach €60,000 for the same app?

Almost always for three reasons: two separate native apps instead of a shared codebase, project management and meetings billed separately, or a scope that includes a custom backend where a managed database would do. Always ask for the breakdown in hours.

### How long does it take to build an app?

From 4 weeks for a minimum product to 14 or more for an app with a custom backend, payments and several integrations. Scope drives the timeline, not headcount: adding people to a small project rarely speeds it up.

### What does app maintenance include?

Yearly OS updates, store policy changes, bug fixes, monitoring and security dependencies. Budget 15% to 20% of the initial cost per year, even if you add no new features.
