As answered by people managing IDroo and StackSource.
IDroo's answer
iDroo combines a collaborative whiteboard with tools for teaching before, during and after a lesson. Teachers can work through equations, diagrams and annotated worksheets with students, then connect that work to courses, assignments and feedback. Live Group Lessons add private student workspaces alongside a shared teacher board, so teachers can follow individual progress while teaching the group.
IDroo's answer
iDroo is a good fit when your lessons involve solving problems together, writing mathematical notation or working through documents. Teachers and students can contribute to the same board, discuss their work through built-in calls, and revisit saved explanations afterward. Courses and assignments support ongoing teaching. A free plan provides a starting point, with paid plans adding features and capacity.
IDroo's answer
iDroo’s primary audience is private tutors, teachers and tutoring teams running online lessons. Its equation editor, drawing tools and document annotation are particularly useful for mathematics and science, while shared boards also support language teaching and other subjects. Students and families can use its study tools for practice and homework support between lessons.
IDroo's answer
iDroo has its roots in a collaborative whiteboard used alongside Skype. It has since grown into a browser-based teaching platform with its own voice and video calls, screen sharing, courses, assignments and live group lessons. The shared whiteboard remains at its centre: a place where teachers and students can explain ideas visually and work through problems together.
