The Mobble Task feature is a great tool to manage work on the ranch, set reminders, and assign jobs.
Here's how:
Via tasks page:
Via maps page:
You can assign tasks to another user, a specific field or to a specific location on the map, and give them a due date. Mapped tasks will display with a red dot on the maps page until they are completed. Fields with assigned tasks will display a task icon in the field list, and you'll receive a notification on the morning of your task due dates.
