EO
Read full descriptionHide full description
This app is a small tool to help moderators with their timekeeping. Ultimately, it is about the democratization of speech shares. The app supports the moderator in keeping the agreed time quotas. Method Equal time slots prevent each speaker from taking more time than the others. Thisβs a sign of respect: βEqual time slotsβ symbolize βEquality of valueβ. The limitation in time helps us to find our focus. We need to be clear, about what is significant and relevant for others. How it works Once you have the app in your hand, it's self-explanatory. Disclaimer This App was created in the context of the Entrepreneurs' Organisation (EO). It was first used in the Munich chapter. Itβs neither an official EO App nor do we follow any commercial interests. Feedback We ask for your understanding but we only sporadically take care of further development versions. Nevertheless, we are looking forward to quotations, feedback, and further ideas. Feel free to contact us: EO-timer@mobile-software.de
