Obtaining new skills and knowledge at work should be convenient. Organizing a knowledge-sharing session or thinking about how to send helpful materials should not be a headache for the team. A dedicated app is one of the simplest yet most appropriate tools for workplace learning; at least, we at Perpetio think so. Our knowledge-sharing app turned out to be a well-organized, clear, and easy-to-use solution. The content shared by the users is the main point, so we kept our UI simple enough.
