property managers
“ Our Mission is one of integrity, accuracy and exceptional service. tApp’s promise is one of a superior user-experience and a secure, simple, streamlined application process.”

About Us

Australia currently faces a serious housing shortage and the average Australian now works a longer working week than any country in the western world. tApp addresses both of these observations with a solution that maximises efficiency at all times.

Everything about our software is designed to streamline processes and create a stress-free user experience. The ancillary services extend beyond the rental application, with information disseminating to preferred utilities and Telco’s for immediate connection and a smoother moving experience. They even include maintenance requests to
property managers.

tApp is a subsidiary service of TRA – Trading Reference Australia / Tenant Reference Australia – and addresses the present day demands of tenants and real estate agents across the country. It is the one-top-shop for all things pertaining to renting a property.
