Hi everyone, I’ve been deep into researching buying a house lately, and I’ve downloaded a bunch of real estate apps. I’ve been scrolling through them so much my eyes are starting to blur. I’ve noticed many people on the forum are also discussing this topic, so I decided to organize my thoughts and experiences as a reference for newcomers. I also welcome any corrections or additional tips from seasoned pros.

The Two Giants of Spanish Property Apps: Idealista vs. Fotocasa
In Spain, when it comes to property search apps, the market is essentially dominated by Idealista and Fotocasa. These two apps hold the vast majority of the market share, offering comprehensive listings for both sales and rentals.
Idealista
This is the undisputed leader, recognizable by its signature green interface. Its main advantage is having the most listings; almost all real estate agencies and private landlords post here. Its map search feature is excellent—you can draw a search area directly on the map, and details like price and size are clearly displayed. The in-app mortgage calculator, while just an estimate, is very helpful for initial planning.
Fotocasa
As the long-standing runner-up, and a key tool for those exploring options like property for residency, Fotocasa’s strength shouldn’t be underestimated. Its interface design feels a bit more modern, and the app runs more smoothly. In certain regions, especially Catalonia, its number of listings rivals Idealista’s, and it sometimes features exclusive properties. It also has a “viewing history” feature, which I personally love, as it makes it easy to revisit properties you’ve already seen.
Key Feature Comparison at a Glance
To make it clearer, I’ve created a simple table comparing the main features of the two apps:
| Feature | Idealista | Fotocasa |
| Number of Listings | The most, widest market coverage | Very high, the main competitor |
| App Interface | Classic and intuitive, powerful map feature | Modern design, smooth browsing experience |
| Filter Options | Extremely detailed, includes almost everything you can think of | Also very comprehensive and easy to use |
| Price Data | Provides area price history charts (helpful for buying in Madrid) | Offers similar data analysis for Spanish real estate |
| Update Speed | Listings updated frequently, but beware of outdated posts | Also very fast, seems to have slightly fewer fake listings |
Personal Tips for Using the Apps
- Don’t rely on photos alone
! Always check the floor plan. Many older Spanish houses have very quirky layouts; no matter how beautiful the photos are, a bad layout is a deal-breaker.
- Make good use of the “save” and “alert” features. Set up your desired areas and filters, and the app will notify you as soon as new listings appear. This is how you get a head start.
- If you see a property you like, don’t hesitate—call the agent directly using the number in the app. Replies to messages are often slow.
As an introvert, I hate it, but you do what you have to for a house.
- Cross-reference listings on multiple platforms. Sometimes the same property is listed on different apps with slight differences in price or information. It never hurts to double-check.
My personal recommendation is to download both apps. Use Idealista as your primary tool and Fotocasa as a supplement, since they complement each other. Additionally, apps like Pisos.com and Habitaclia can serve as good backups. Which app do you all use the most? Any stories about pitfalls to avoid or great deals you’ve scored?
