Read the video description
A 27-second silent tour of three separate app features, using real screens recorded in July and August 2026.
- 0–7 s, “Step into an emergency.” A major-haemorrhage simulation: the patient monitor changes as the case information is scrolled.
- 7–13 s, “Read the trace. Spot the pattern.” An ECG library entry shows a rhythm example, annotations and learning points.
- 13–22 s, “Choose a view. Check your reasoning.” An eFAST exercise shows a probe choice and feedback, then a window choice and confirmation (slowed to make it easier to follow).
- 22–27 s, “Build your clinical skills.” Simulations, ECG and POCUS. Free to start on iOS and Android.
Educational simulation, not accredited training. The video does not show a completed treatment sequence or a patient outcome.
Free to start. Pro: $4.99/month or $39.99/year. US reference prices; your store shows the local price.
