Find a flat in Poland before everyone else — and know what you're renting.
RentCat watches OLX, Otodom and Adresowo around the clock and sends you new flats in Telegram the moment they appear. Open one and the app shows the rest: the real monthly cost, whether the price is fair, noise, sunlight and how long it takes to get anywhere.

From a new listing to a viewing, in one app
No installation, no account: RentCat opens inside Telegram.
Say where and how much
Pick a city, tap the districts on the map (or draw your own area), set your budget and rooms. The app shows how many flats match as you go.
New flat for your search
2 rooms · 46 m² · 2,820 zł — Wola. Tap to open it in RentCat.
New flats come to you
Every new match arrives in your Telegram chat — every hour, once a day, or the moment it's listed. Home keeps your searches and what's new since you last looked.
Open a flat, see everything
Photos, the price and how it changed, the Deal Score, the full monthly cost and the map around it — then save it, or message the owner.
The real app, filmed on a phone
No mock-ups: these are screen recordings of RentCat in your language. Hover over a phone to pause it.
Everything a listing doesn't tell you
Ads show a price and some photos. RentCat adds what you'd usually find out at the viewing — or after you've moved in.
Search exactly where you'd live
Pick a city, tap districts on the map or draw your own area, and set a budget against a live chart of what flats there actually cost. The number of matching flats updates as you go.

- Pet-friendly, furnished only, no agency fee, no najem okazjonalny, your own words to skipPremium
Is the price fair? See it at a glance
Every flat gets a Deal Score: its price against similar flats nearby. Sort any list by best deal and the bargains rise to the top — or by newest, price, size or price per m².
- 🟢 Super deal, 🟡 market price or 🔴 overpriced, from 0 to 10
- Best deal first, in every list and in your saved flats
- Only good deals: set a minimum Deal Score on a search
- The same flat posted on two portals shows once
The real monthly price
Rent, the building fee, electricity, gas, internet and parking — read from the ad itself, with typical costs where it says nothing, so you know the total before you call.
- Rent, czynsz, utilities, internet and parking — added up
- Each line quoted from the ad, or marked as a typical cost
- Reads “czynsz w cenie” and “+ media” the way Polish ads say it

Renters love the calm, clarity and time advantage
RentCat was built to make apartment hunting less stressful and more predictable.

“What I appreciate most is exclude words and Deal Score. I finally don't waste time on listings that don't fit anyway.”
“Everything's in Telegram: alerts, saved apartments and reminders. It genuinely calms down the whole search process.”
“For me the biggest plus is speed. Good listings on Polish portals disappear in a flash.”
