Calonex

The client. A US rental housing platform: renters search, tour, apply, sign a lease and pay rent in one app. It is built to take the friction out of renting, with no paper forms, no chasing landlords and no hidden fees, from the first search to moving-in day.

Beyond renters it serves property professionals directly: landlords listing properties, brokers and agents, property managers and building managers, and referral partners. It runs on iOS, Android and the web.

Figures published by Calonex about its own platform. They describe the client, not work done by us.

How the platform works

  1. Search and tour

    Find verified homes nearby and book a tour in one tap, with no spam and no fake listings.

  2. Apply online

    Submit one application, get screened fairly, and track its status in real time.

  3. Sign the lease

    Negotiate terms and e-sign digitally. Nothing to print, nothing to mail.

  4. Pay and settle in

    Set up autopay, message about maintenance, and keep every receipt in one place.

What it offers

  • No hidden fees: the rent you see is the rent you pay.
  • Verified listings, each tied to a real, verified owner or manager.
  • Tour, apply, sign, pay and message from a single app.
  • Bank-level encryption on payments, with downloadable payment history.
  • Fair screening through a CX Score, so qualified renters are approved faster.
  • Saved searches with instant alerts, an affordability calculator on the 30% rule, one renter profile reusable across applications, and pet-friendly filtering with clear policies.
  • Search described in plain English rather than set with filter dropdowns, which Calonex announces as coming soon.
