Many of our experts sell out quickly.

This feature is free to use and you'll only get charged when they confirm the booking (a credit card pre-auth is required).

It depends on the specific expert. Some experts add sessions weekly and others add sessions monthly. We recommend booking as soon as possible to not miss out.

Yes. You can reschedule calls at least 48 hours before the session. For any cancellations, or reschedules within 48 hours of the session, we do charge a fee to compensate the expert for the last minute change. All cancellations or reschedules must happen in our mobile app.
