Google Calendar adds Goals to help you better yourself
Google Calendar now features a Goals option, helping you to organise your day so you can find time to learn and develop skills. Goals lets you input what you’d like to do, how often you need to practice, and what times might suit you best, and the Calendar will slot in your activity.
For the app to work effectively, you’ll need to enter all meetings and scheduled activities into Calendar. If you do so, Calendar will even rejig your schedule if a meeting happens to run over.
