Plugin SEARCH: no luck finding a task manager, to-do list, calendar for my needs

Hello WordPress community! I am looking for a plug-in to help a community of friends to manage certain tasks on a daily basis. We would like to be able to check off a number of tasks each day and be able to show privately or publicly on a calendar whether we have completed those tasks. I have had no luck searching wordpress.org, but I may just be looking in the wrong direction.

Ideally the admin could create generic tasks, but users could also create their own tasks for their own money.

It would be a BONUS if there were some sort of tracking that would allow users to view their progress over an extended period of time. For example, they could see if they are improving on their day-to-day completion of certain tasks. It would also be a bonus if some tasks could be measured on a scale, or with some numerical value, instead of simply yes/no complete/incomplete.

Thanks for ANY suggestions or direction. I am new to this form and hope it can be of help!
