Best apps to find an apartment in Barcelona (2026)
We build Prio, so we have a stake here. Every other row comes from the tool's own pages, linked and read on 30 October 2026; prices and features change, so check them before you subscribe.
Short answer, October 2026
There is no single best app. Use Idealista's own saved-search notifications as the base, since Idealista is where most Barcelona listings are, and add the alert tool whose limit you can live with: Fotocasa or Habitaclia notifications for those sites only, an aggregator such as CasaRadar or RentAlert if you want several sites in one feed (RentAlert reads them every hour), or Prio if you want Idealista and Badi in Telegram usually 2 minutes ahead of Idealista push notifications. See how Prio works.
The tools compared
| Tool | Covers | How you are notified | Price as stated | What it does not do | Source (read 30 Oct 2026) |
|---|---|---|---|---|---|
| Idealista | Idealista listings only | Saved searches with notifications by email or push in the free Idealista app. | Free app. | Covers Idealista listings only. | idealista.com |
| Fotocasa | Fotocasa listings only | Saved searches with notifications by email or push in the free Fotocasa app. | Free app. | Covers Fotocasa listings only. | fotocasa.es |
| Habitaclia | Habitaclia listings only (strong in Catalonia) | Email. Habitaclia says it emails the latest properties that match your search, and you can also set an alert from one ad to receive changes to that property. | No price is mentioned on the page; you can save as many alerts as you like. | Email only on the page we read; no other portal. | Habitaclia alerts page |
| Badi | Rooms in shared flats | We found no description of new-room alerts on the public Badi pages we read (about page, Barcelona rooms page, Badi Plus FAQ). Check the notification settings in the app. | Not stated on those pages. | Not documented, so we do not claim anything. | Badi |
| Prio | Idealista (rentals and sales) and Badi (rooms) | Telegram. New matching listings usually 2 minutes ahead of Idealista push notifications, with photo, price, phone number when shown, map link and a ready-to-send message in Spanish. | 7-day free trial, no card; then EUR 4.95 (Roommate, Badi), EUR 19.90 (Renter, Idealista rentals) or EUR 49.90 (Buyer, Idealista sales) a month. | No Fotocasa, Habitaclia or agency sites; it does not contact landlords or sign for you. | What is Prio?, pricing |
| RentAlert | Rooms and flats in Barcelona from 11 agency sites and platforms | WhatsApp. Its site says listings are read every hour and new matches are sent to your WhatsApp. | EUR 10 a month, "cancel in one tap on WhatsApp" (its site, 30 October 2026). | Checked hourly by its own description, so it is not built for minute-level speed. | rentalert.app |
| CasaRadar | Barcelona aggregator: "major and small real estate listing websites" | Email or WhatsApp on the free plan; its pricing page lists instant email, Telegram and push notifications for PRO. Its homepage promises instant alerts, its FAQ describes daily updates of 2 to 25 listings. | Free plan: 3-day trial, no card. PRO: EUR 19.95 a month, billed EUR 39.90 every 2 months (its pricing page, 30 October 2026). | Does not publish a speed figure in minutes. | casaradar.io, pricing |
How to choose
- Relaxed search or low competition: the free saved-search notifications of the Idealista and Fotocasa apps are enough.
- One feed across several sites: an aggregator such as CasaRadar or RentAlert; check how often each one reads the sites, because that sets how late an alert can be.
- Being among the first on Idealista: an alert service built for speed on that portal, such as Prio, usually 2 minutes ahead of Idealista push notifications.
- A room: Badi, plus an alert tool that covers it (Prio covers Badi).
Whichever you choose, prepare your file and check each listing before you pay: see the step-by-step guide to finding an apartment in Barcelona and the free scam checker.
Frequently asked questions
What is the best app to find an apartment in Barcelona?
No single app wins on every point. The Idealista and Fotocasa apps are free and notify you about saved searches on their own sites; Habitaclia emails alerts for its own listings; CasaRadar and RentAlert aggregate several sources; Prio sends Idealista and Badi listings to Telegram, usually 2 minutes ahead of Idealista push notifications.
Are the portals' own alerts enough?
For a relaxed search, yes. In a busy market such as Barcelona, where the average rental ad gets 54 contacts (Idealista 2024 annual report, via Barcelona Secreta), an alert that reaches you sooner can matter.
How much do these tools cost?
The Idealista and Fotocasa apps are free. Prio has a 7-day free trial, then EUR 4.95, 19.90 or 49.90 a month depending on the plan. RentAlert states EUR 10 a month. CasaRadar has a free plan and a PRO plan at EUR 19.95 a month billed EUR 39.90 every 2 months. Habitaclia does not state a price on the alerts page we read.
Do alerts replace checking a listing before paying?
No. Whatever tool you use, check each listing before you pay: the free scam checker compares an Idealista listing with real neighborhood prices.
