Dotzza — Projects, Together Healthcare education involves more than learning. There are dissertations, research projects, presentations, journal clubs, assignments, deadlines, documents, reviews and countless conversations happening along the way. Dotzza brings that work together in one shared workspace for healthcare students, mentors and educators. Create a Teamspace for your project, bring your team together, organize tasks and timelines, share files, discuss work, track progress and keep every stage of the project visible. Built for healthcare education Dotzza is designed around the kinds of academic and research projects healthcare learners actually work on — not adapted from a generic task list. Start with structured templates for projects such as: - Dissertation & Thesis • Short Studies & Research Projects • Case Reports • Journal Clubs • Systematic Reviews & Meta-analysis • Seminar & Paper Presentations • Poster Presentations • Journal Publications • Community Health Projects • Healthcare Camps • Research Protocols • Grant & Funding Projects • Curriculum & Workshop Projects • Doctoral Research Choose a project type and start with structure instead of a blank page. One workspace for the whole project Teamspaces Create a dedicated workspace for each project, with members, roles, timelines and tasks in one place. Tasks & Project Views Plan and track work using Kanban, List and Calendar views. Everyone can see what needs to happen and who owns it. Files & Documents Keep research files, submissions, presentations and other project documents organized with the project instead of scattered across conversations and devices. Chat & Collaboration Discuss work where the work happens. Keep project conversations connected to the people, tasks and documents they relate to. Objectives & Key Results Turn broad academic goals into measurable outcomes and track progress with your team and mentor. For students Move from “Where do I start?” to a clear project plan. Organize your work, collaborate with peers, submit files, track deadlines and see your progress throughout the project. For mentors & guides Get a clearer view of the students and projects you supervise. Follow submissions, progress and project activity without having to piece everything together from separate conversations and files. For institutions Bring projects, students, mentors and departments into a more organized collaborative environment. Gain visibility across academic projects and support students before small delays become bigger problems. Work wherever healthcare education happens Dotzza is available on iPhone, iPad, Android and the web, so your project stays accessible between lectures, clinical postings, library sessions, meetings and research work. Less searching. Less scattered work. More clarity about what happens next. Dotzza is a project collaboration and project management platform for healthcare education. It is not a clinical system and does not provide medical advice, diagnosis or treatment recommendations. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
