Discover the latest evidence, lessons, and podcasts for your field; ask Tunza AI questions grounded in public evidence and your own material; practice fictional patient encounters; and turn your lectures and notes into podcasts, flashcards, and study guides. DISCOVER — FREE WITH YOUR ACCOUNT The app opens on Discover: new trials, reviews and guidelines, drug safety alerts, public health news, video lessons and clinical podcasts, one at a time. Swipe up for the next. Where publishers' terms allow, updates become short stories: what was done, what was found, how strong the evidence is, and why it matters. Listen, Save, Cite (APA/AMA), Poke holes or open the original. "For you" follows your field (nursing, NP, PA, medicine, pharmacy, or public health), your topics, and, if you allow it, your classes and Library. Discover stays free after your trial. ASK TUNZA AI Type or dictate a question, or attach a photo or file. Answers draw on public evidence (research, drug labels, trials and agency guidance) and, if you choose, your own material, with sources to check. Ask for a quiz, diagram, drug card, clinical prep sheet, or podcast. MY CLINICAL DAY Work through fictional patient encounters for your role and specialty: review the chart, talk with the patient, place orders, write your note, and get a debrief on your reasoning. Discuss fictional cases with classmates in peer case conferences. CLASSES AND LIBRARY Upload a syllabus or timetable to see classes and deadlines on a calendar, and take lecture notes that sync across devices. Keep slides, PDFs, Word files, and screenshots in your Library, automatically sorted by subject, and record lectures with permission.

Verdict

The call

The clearest difference is monetization model: Dust to Cosmos at free against YourStudy Space's freemium. Dust to Cosmos also leads on update cadence (every 5 days vs fortnightly) and ratings volume (7 vs 1). YourStudy Space's advantage is iOS requirement (15.0 vs 17.0). On price, rating, review sentiment and ads there is nothing between them.
