Practice the whole patient encounter, on your own schedule.
An online patient simulator for medical students. Practise clinical reasoning and patient assessment through virtual clinical encounters, AI-assisted history-taking and feedback.
Knowing the answer and managing the patient are different skills.
Textbooks and question banks teach you what is true. A patient asks what you will do next, in order, with incomplete information. That takes repetition, and rotations rarely give you enough of it. OnCall gives you as many encounters as you want, with feedback after each one.
The full patient encounter, not a multiple choice quiz.
Every case follows a real consultation. You take the history, examine, decide and treat, then see exactly where your reasoning held and where it slipped.
The complete encounter
History
Interview the patient, including AI history taking, and decide which questions matter.
Examination
Choose and perform the relevant exams and interpret what you find.
Investigations
Order tests and imaging and read the results.
Diagnosis
Weigh the differential and commit to a diagnosis.
Treatment
Set a management plan and document the encounter.
Feedback
See scored feedback on every decision, then try the case again.
See your score. Learn from your decisions. Try again.
Scored feedback
Each case is scored on the relevance of your choices. The feedback shows which questions, exams and decisions mattered, and which ones you missed.
Practice and feedback
Work through patient encounters and review feedback on your clinical decisions. OnCall’s gamification helps you build a practice habit: earn XP, unlock achievements and keep your streak going.
Repeat any case in your plan
No timer, and unlimited attempts on every case included in your plan. Paid plans open the full library.
AI communication cases
Our AI communication cases let you put communication into practice. Practice your communication skills through conversations with a virtual patient. After each conversation, receive AI feedback based on what you said and how you responded. See what you did well, identify areas to improve and get practical suggestions for your next patient conversation. Put the feedback into practice to build clearer, more confident communication. AI history-taking included, reasonable use limits apply.

Will this help my OSCE score?
A 2024 study in eClinicalMedicine, part of The Lancet Discovery Science, enrolled 105 students in a four-week programme combining CyberPatient, Lecturio and faculty teaching. OSCE scores rose 53.6 points among the 14 Level 2 students who completed both assessments. That was a structured programme rather than self-study alone, so treat OnCall as the practice layer, not a guarantee.
Do I need a credit card to start?
No. Start with 3 free cases and 2 AI encounters. The free plan needs an email address and no credit card.
Is it only for medical students?
No. The same cases are used in nursing, physician assistant and allied health programs.
What do I need to run it?
A web browser on a laptop or desktop. Cases are built for a full-size window, so a phone screen is too small for them.
Is there a time limit on cases?
No. The platform does not impose time limits, and you can repeat any case as many times as you like.
