RealtyCalendar is an Android app that helps you manage your rental properties for short-term rentals across multiple platforms through its channel manager service. With this app, you can easily manage the occupancy of your properties, view customer information, send SMS and messages with photos and information about your properties, and check customers against a fraud database using their phone number or passport series. There is also a role-based access control feature that allows you to grant different levels of access to different users.

The interface is user-friendly and easy to navigate, making it simple to keep track of your properties and customers. The app is free to use and is an excellent tool for anyone who manages rental properties for short-term rentals. However, it is only available for Android devices and does not have a web interface. Overall, RealtyCalendar is a great choice for anyone looking to streamline the management of their rental properties.
