Insteps is a productivity app accessed through web. Insteps allows you to create to-do lists for your group work based on your interest. In each to-do list item, you can include explanations and details, all users can comment. You can see stats about how well users have completed the to-do list items. You can share the list to all people you want to.

When I was in charge of a group work, I had to explain the same thing over and over again to everyone. Everyone had similar questions. I then came up with a product called Insteps.
