A structured study companion for building differential diagnosis skills — without the guesswork of loose notes or scattered flashcards. Designed for residents, psychiatry and psychology trainees, and social work and counseling students, this app turns symptom review into a guided clinical reasoning exercise. Select from roughly 67 presenting symptoms, rate severity as mild, moderate, or severe, and add clinical context like duration, onset, and functional impairment. From there, explore ranked differential considerations across 33 disorders, informed by DSM-5-TR criteria, with a clear breakdown of how well each case matches diagnostic criteria. Every disorder displays ICD-10-CM codes alongside legacy DSM codes, so you can practice thinking the way real clinical documentation works. NARROW THE DIFFERENTIAL When several diagnoses remain in contention, a guided decision tree asks one targeted question at a time — each encoding a published DSM-5-TR exclusion criterion, required course, or hallmark feature. Considerations are ruled out or move up as you answer, with a teaching note explaining why each question matters, and ruled-out disorders stay listed with the reason recorded. CHILDHOOD & ADOLESCENT COVERAGE ADHD, Autism Spectrum Disorder, Oppositional Defiant Disorder, Conduct Disorder, Disruptive Mood Dysregulation Disorder, Separation Anxiety Disorder, Selective Mutism, Reactive Attachment Disorder, Tourette's Disorder, Language Disorder, and Intellectual Disability — with the age-of-onset, course, and severity questions that separate them. EVERY SOURCE IS CITED All clinical content is cited to public, authoritative sources — the DSM-5-TR (American Psychiatric Association), ICD-10-CM (CDC/NCHS), CMS official coding guidelines, WHO ICD-11, the National Institute of Mental Health, NIDA, NIAAA, MedlinePlus, and NCBI Bookshelf. A built-in Sources & References screen links directly to each one, and every disorder screen lists the specific sources behind its content. Sharpen your skills with 9 practice case vignettes spanning beginner, intermediate, and advanced difficulty. Commit to a diagnosis, then review teaching points that reinforce key distinguishing features — ideal for exam prep, supervision discussions, or independent study. Save your case sessions for later review, and export text summaries through the iOS share sheet for study groups, journals, or supervision notes. Privacy is built in from the ground up: everything runs 100% on-device, with no account, no network requirement, and no analytics tracking your activity. Your practice cases stay yours. This is a study aid for building clinical reasoning skills — not a diagnostic device, and not a reproduction of the DSM manual. Diagnostic criteria are paraphrased in summary form for educational purposes; consult the DSM-5-TR for authoritative wording, specifiers, and exclusion rules. DSM-5 and DSM-5-TR are trademarks of the American Psychiatric Association. This is an independent educational product and is not affiliated with or endorsed by the American Psychiatric Association. Whether you're prepping for boards, working through case conceptualization, or building diagnostic confidence early in your career, this app gives you a private, structured space to practice.
