When you send a task to someone, you need to know their email address. We keep track of the email addresses you’ve previously used. But if you would like to get access to all your contacts, you can log in with your Google account. This way, you get access to your full address book.
To get access to your full address book, choose ‘Login with Google’ on the login screen.
If you are using Sendtask with a different email address than your Google account or you would like to add multiple Google accounts, you can do that as well. Just register/login with the Google account you have not used before, then go to Settings and add the email address of the account you’ve previously used.
