Personality Assessor

Do you work with, live with, or know someone whose behaviour keeps leaving you confused, drained, or manipulated? Personality Assessor gives you a calm, structured, research-based way to make sense of what you are experiencing - and to decide what to do next.

START WITH A QUICK CHECK
Not sure what you are dealing with? Answer 12 everyday questions about the person, one at a time - "Not sure" is always an option. The Quick Check points you to the patterns worth a closer look, and ticks your "Yes, often" answers for you in the full checklist.

SIX RESEARCH-BASED CHECKLISTS
• Narcissistic Personality Disorder (NPD) - 9 DSM-5-TR criteria
• Antisocial Personality Disorder / Sociopathy - 7 DSM-5-TR criteria
• Psychopathy - 20 indicators based on the Hare PCL-R
• Borderline Personality Disorder (BPD) - 9 DSM-5-TR criteria
• Machiavellianism - 9 indicators from Dark Triad research
• Covert (Vulnerable) Narcissism - 9 indicators from clinical research

Tick the behaviours you have consistently observed - not isolated incidents. You see how many indicators you noted, what clinical practice would require before a professional could make a diagnosis (for the DSM-based checklists), and plain-language guidance on protecting yourself: stay aware, set boundaries, protect yourself, or limit contact.

SEE HOW THINGS CHANGE
Every assessment is kept, so you can re-check a pattern over time and see what has changed since last time.

INCIDENT JOURNAL (PRO)
Write down what happened, when, and how you felt - close to when it happens. Link entries to the behaviours they are an example of, and the journal shows you which patterns keep coming up. Your first 3 entries are free.

SUPPORT WHEN YOU NEED IT
Where the guidance suggests reaching out, the app lists free, confidential helplines for your region. They are always available in Settings, too - no assessment needed.

PRIVATE BY DESIGN
No account, no ads, no tracking. Your data is stored on your device and, if you use iCloud, synced through your own private iCloud account. The developer never sees it.

FREE AND PRO
Every checklist, the Quick Check, your history and the research library are free, for up to 2 people. Pro unlocks the journal without limits and unlimited people - a one-time purchase, with a 14-day free trial. No subscription.
