By App is a simple task management tool that assigns users their own unique subdomain. Through By App you can create a list of tasks for yourself and organize the list by semantic day (tomorrow, next week) or by date. If your priorities shift, you can reorganize your list with the simple drag and drop interface. By App is advertising a multiple user capacity, but it didn’t seem to be functioning when I tried it.

Applications for Education
A lot of students struggle to organize and prioritize deadlines. By App is one tool that could help students organize and prioritize deadlines. You could also make your By App list public and link it to your classroom blog for students to check for approaching deadlines.
