Two answers now, so your streaks and weekly totals count the right days from the first session.
Pick your current rotation and the dashboard puts that specialty first: its topics, its podcasts, its progress.
Not started, in progress, done, needs revision. Hide the ones you will never need.
The timer runs on the server, so it keeps counting if you lock your phone. It logs the session itself.
Marking a topic done books its first review for tomorrow. Rate it, and the gap grows.
Podcast episodes are filed by specialty. Mark one listened and its length counts as study time.
Nothing is filled in for you. Every number starts at zero and moves only when you study.
Your queue is empty: tap the bookmark on any topic to decide what you study next. Everything here can be changed later in Settings.
