Productive lets you create both recurring and one-time tasks with ease.
On the main screen tap the blue + button and on the habit screen tap on the "One-time task" button.
On the One-time task screen, you will be able to type a name for your task, add a description (optional), and choose its icon and color.
Next, tap the calendar icon to choose the date when the task will appear in your schedule.
To stay on track, you can enable the "Get a reminder" option. Then, tap "Add a reminder time" to choose when you'd like to receive a notification from Productive—prompting you to start or complete your One-time task.
