Days with unfinished tasks happen, deal with it. Better still let US deal with it for you!
Moleskine Journey provides a way to automatically move all the today's unfinished tasks to the next day.
The tasks are moved when the day changes and this automation affects only the current day's unfinished/not-done/unchecked tasks (to move unfinished tasks to a different day you can use the Move unfinished * buttons).
iOS App
On the mobile app this setting is in the same places: Tap on the three dots menu in a day page or open the Settings menu in the left side menu
and then check the Auto move unfinished tasks setting.
Please note that this is a Premium feature feel free to try it during your trial period.
Fun doesn't end here, references to project can be auto-moved if you want.
