In Wunderlist you can set up recurring to-dos for things you need to do on a regular basis. Simply click or tap on an item to open its detail view, add a due date, and select a recurring option next to it.
Here you have the option to repeat the to-do every day, every week, every month, or every year. You can also further customize the to-do to repeat, for example, every 3 days or 5 months.
Recurring to-dos are marked with the small recurring icon.
After you check off a recurring to-do, the next occurrence of that to-do will appear following a sync. You will see that it has the same name, subtasks, and note, but with the new due date. If you also set up a reminder for the initial recurring to-do, then the new reminder will be adjusted according to the new due date.
Please note: In order to set up recurring to-dos, you must have a confirmed Wunderlist account.
