New: Study Mode — find out why a disorder isn't in your results, and compare two disorders side by side. Plus guided mode, PDF export and ICD-11 codes.
Psychological Symptom Analyzer (PSA) helps you explore how a set of symptoms relates to the criteria of recognised mental disorders. Select symptoms, add context, and see which disorders' criteria match — with a clear explanation of what matched, what's missing, and why.
PSA is an educational tool for students, trainees and curious users. It does not provide a diagnosis.
MATCHES THAT EXPLAIN THEMSELVES
• 376 symptoms and 39 context items (duration, onset, age, possible causes), grouped by diagnostic chapter
• Results are matched against each disorder's criteria structure, including required features, thresholds and exclusions
• Clear labels: Criteria pattern met, Possible, or Partial match, with a strength bar
• Tap any result to see matched criteria, what still needs confirming, and what wasn't selected
GUIDED MODE
Not sure where to start? Answer a few short screening questions and PSA shows only the symptom areas that apply, then asks about duration and context. After analyzing, Refine asks only for what uncertain results are missing.
STUDY MODE
• Why isn't it listed? Pick any disorder and see exactly why it's not in your results: a missing required feature, a cause not selected, or simply ranking below the top 10.
• Compare: Put two disorders side by side to see shared criteria, what's unique to each, timing requirements, and what rules each out.
208 DISORDER PROFILES
Every profile includes a plain-language overview, key features, the criteria checklist, onset and course, prevalence, specifiers, risk factors, linked differential diagnoses, ICD-11 codes and a link to Wikipedia.
EXPORT AND NOTES
Tick results and criteria, add notes, and share a clean PDF or text summary through Mail, Files, AirDrop or Print. Every item is listed and marked.
DESIGNED FOR iPHONE AND iPAD
• Keyboard shortcuts on iPad
• VoiceOver, Dynamic Type up to the largest sizes, Increase Contrast, dark mode and Reduce Motion
• Your selections and notes stay on your device: no account, no tracking, no data collection
SAFETY FIRST
If thoughts of suicide or self-harm are selected, PSA shows where to find help right away.
IMPORTANT
PSA is for educational purposes only and is not a substitute for assessment by a qualified mental health professional. Results depend on the information entered. If you or someone you know is in crisis, contact local emergency services immediately.
SOURCES
Criteria and profiles are plain-language educational summaries based on the DSM-5-TR (2022). PSA is not affiliated with, sponsored by or endorsed by the American Psychiatric Association. DSM-5-TR is a registered trademark of the American Psychiatric Association. Diagnostic codes are from ICD-11 for Mortality and Morbidity Statistics, World Health Organization.
I love the quick and easy access to the disorders. However, the entire set of personality disorders are missing. Also the drag and drop takes too long. Should be boxes to check instead. Other than this would be 5 stars.
Pretty good

I find the app helpful for exploring psychological diagnoses and symptoms and I expect to use this app frequently myself and I will likely refer my supervisees and students to this app. Would be nice to be able to expand or collapse symptoms by category, letter groups, etc.I'd also love to see checkboxes next to symptoms that the user could tap to check/uncheck so as to keep track of observed/not observed symptoms for a particular diagnosis.Checkboxes at the diagnosis level could also be helpful.Another helpful feature could be "user-defined" diagnoses or categories that the user could set up to include symptoms from existing diagnoses and/or symptoms that the user could add him/herself.The addition of the WHODAS 2.0 disability rating scale would be helpful too (i.e., the WHODAS [World Health Organization Disability Assessment Schedule] in the DSM-5 has replaced the GAF [Global Assessment of Functioning] that was used in DSM-IV).
Love This App!

I love it and use it as a quick reference in practice. Nice price, too. Thank you!
