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 menuand 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.
