There is now a 'daily shutdown' ritual built into Sunsama.
When you plan your day in the morning, you can choose when you'd like to wrap up your work for the day.
When this time rolls around, you'll see an in-app notification to shut down your day.
This opens the daily shutdown ritual, which gives you a chance to review your work for the day, reflect, and then pack up and go home (or just stop working).
Note: the daily shutdown is only for folks who plan their day in the morning. If you plan your day the night before, the current planning process will continue to apply.
