This document presents a proposal for an educational collaboration app called LearnMixer. It aims to make group work easy and fun for students by allowing them to share, see and create content on their mobile devices. The app would support active learning on the upcoming Estonian educational cloud platform. User research was conducted including interviews and tests with students, which provided positive feedback but also identified usability issues to address like improving tutorials and learnability. The proposal seeks 30,000 EUR in funding to launch initially in the Estonian market and believes there is significant growth potential among other developed countries. Revenue would come from in-app purchases or subscriptions.
