Personality Assessor
Spot Patterns. Set Boundaries.
Free · In-App Purchases
Recognise toxic personality patterns at work and in life. Six research-backed checklists. All data stays on your device.
Personality Assessor helps you recognise established behavioural patterns in the people around you — at work, in relationships, and in your personal life — so you can make informed decisions about how you engage with them.
NOT A DIAGNOSIS. AN AWARENESS TOOL.
This app is for anyone who has ever felt confused, manipulated, or drained by someone in their life and wondered why. Using established research criteria, it gives you a structured way to document what you observe across six well-studied behavioural categories.
HOW IT WORKS
Add the people you want to understand better. For each person, work through category-specific checklists based on widely referenced research frameworks — including Narcissistic Personality patterns, Antisocial behaviour, Psychopathy indicators, Borderline patterns, Machiavellianism, and Covert Narcissism.
As you complete assessments, the app calculates a structured alert level — from Observe through Caution and Alert to Critical — based on the breadth and severity of patterns detected. Each level includes clear, practical guidance on how to protect yourself and adjust your behaviour accordingly.
GUIDANCE THAT ACTUALLY HELPS
Personality Assessor doesn't just flag patterns — it tells you what to do about them. Each alert level covers:
• Whether to set firmer limits
• How to protect personal and financial information
• When to document key interactions
• When to limit contact and seek external support
RESEARCH-BACKED, NOT CLINICAL
Every checklist is derived from peer-reviewed research and publicly available professional references. The Research section gives you direct access to primary sources, key findings, and the academic work behind each category — so you understand the basis of what you're assessing.
YOUR DATA, YOUR ICLOUD
All data is stored privately on your device and synced across your iPhone and Mac using your personal iCloud account. Nothing is shared with third parties. No account required.
DESIGNED FOR REAL LIFE
Personality Assessor is for professionals dealing with difficult colleagues, individuals navigating challenging personal relationships, team leaders trying to understand team dynamics, and anyone who wants a structured way to make sense of confusing behaviour.
This is not a medical device. It does not provide diagnoses and is not a substitute for professional advice.
If you have concerns about your own mental health or someone else's, please consult a qualified professional.
