Task kitty is a great new app from us that lets you create tasks, and share them with others.
So if you are planning a trip together, working on a project together, or doing any set of tasks with other people, you can keep track of what needs to be done. Each person can also mark a task as done, and you can see when they finished it.
Create as many task boards as you need, full of tasks, and mark them off when you are done. Share them with as many people as your want, and they can add tasks, and mark them as done as well.
