Sanvello will send you a reminder to complete a daily mood check-in. You have some options on when you receive this prompt. You can choose a time that works best for you, or choose to receive a reminder randomly throughout the day, or after 7PM.
To make changes or disable the mood reminders, open "Notifications and Preferences" in your Account Settings. {Account Settings can be found by tapping on the gear wheel icon(⚙) in the upper right corner of the ME screen in your app.}
