Fotocasa, the official app of the famous web portal of the same name, lets you look through thousands of houses for rent or sale. Just like on its website, this app allows you to use dozens of different search criteria to find the house of your dreams.
Users can pick the exact part of the city they're interested in. For example, if you only want to live in the center of the city, simply indicate that. If you're also looking for an apartment with three or four rooms, or a furnished house to rent, you just have to include that in the filters.
The app offers a feature that the website doesn't: it allows you to use your Android device's current location to find nearby properties. That means if you're passing through an especially beautiful neighborhood and want to know how much a flat there would cost, all you have to do is look at the app.
Fotocasa is a good official app from a good web portal that will help you find a house. Whether you're looking to rent an apartment that's 25 square meters or looking to buy a Victorian mansion with views of the Miskatonic river, this is the app to use.
