Whether you're a worried parent, a young adult, or simply someone who wants to know their own mind — ANXAPP offers the only honest, science-backed answer that exists. Ten minutes. One score. A lifetime of clarity.
What ANXAPP Does
Identify. Prevent. Recover.
ANXAPP is not a mood tracker, a breathing app, or a chatbot. It is a science and evidence-based tool built on 30 years of direct practice — the only application capable of identifying genuine anxiety condition risk before one develops.
The Assessment
A 60-question assessment built on the neuroscience of the anxiety response — targeting the stable personality traits and behavioural patterns that determine long-term vulnerability, not how you feel today.
The Score
A percentage score across five predisposition bands — Minimal to Very High — giving a clear, honest picture of individual risk. Not a clinical diagnosis; a scientifically grounded measure of the conditions that precede anxiety condition onset.
The Pathway
ANXAPP connects predisposition insight directly to TRT — the world's most proven anxiety recovery programme with 650,000+ full recoveries. It identifies the predisposition, implements prevention, and makes recovery available.
Conditions Tested For
Accurate Assessment Across the Full Anxiety Spectrum
ANXAPP assesses predisposition across all anxiety conditions — built on 30 years of research, testing and experience in psychology and psycho-educational practice.
Your Result
A Score That Could Change the Direction of Your Life
When you complete the ANXAPP assessment, you receive something no GP, therapist, or mental health platform has ever been able to offer you: a precise, honest measure of your personal predisposition to developing an anxiety condition — produced before one has taken hold.
Your score is expressed as a clear percentage, placing you within one of five predisposition bands — from Minimal through to Very High. Each band is not a label or a diagnosis. It is a scientifically grounded picture of the neurological and behavioural conditions inside you right now, and how likely they are — if left unaddressed — to produce an anxiety condition at some point in your life.
This is not how you feel today. This is not a mood questionnaire. It is a deep, stable read of the traits and patterns you carry — many of which you may have lived with so long you have never noticed them at all. ANXAPP surfaces them, names them, and quantifies them, so that for the first time you have genuine, actionable intelligence about your own risk.
"Most people discover their anxiety predisposition only after a disorder has already developed. ANXAPP changes that."
— Charles Linden, Founder, The Charles Linden Institute
If your score is low, that is genuinely reassuring knowledge — and knowledge that has real value for your mental health, your relationships and your working life. If your score is elevated, it is not a sentence. It is an early warning that gives you the rarest possible gift in mental health: time to act before a disorder begins. And if a disorder has already developed, your score tells you exactly how deep the predisposition runs — and precisely what level of engagement with TRT Therapy will produce a full recovery.
Every result, regardless of band, connects you directly to the appropriate level of support within TRT Therapy and the Linden Recovery Programme — the world's most proven anxiety recovery pathway, with over 650,000 full, documented recoveries. Your score is not the end of the process. It is the beginning of it.
Who It Serves
One Tool. Every Person. Every Sector. Every Stage of Life.
ANXAPP does not belong to one demographic, one industry or one moment in life. It belongs to every person who has ever wondered why anxiety feels closer for them than for others — and every organisation responsible for the wellbeing of the people in their care. There is no situation where knowing your anxiety predisposition is not a life-changing advantage.
CEOs, Executives & Senior Leaders
Many leaders carry an undiagnosed predisposition they have never had language for. ANXAPP provides a precise measure of neurological anxiety risk and a direct path to eliminate it — so performance and clarity are never quietly compromised.
Every Workplace & Every Workforce
Anxiety disorders cost UK employers over £28 billion a year. ANXAPP identifies vulnerability before it becomes absence or breakdown — the only predictive tool that exists. Preventative, at source.
Children, Young Adults & Their Families
Anxiety disorders overwhelmingly begin before age 21. ANXAPP provides a clear, private assessment and a route to full resolution — before a disorder defines a young person's education, relationships, or life.
Every Individual — Regardless of Background
No referral, diagnosis, or symptoms required. Ten minutes. One score. A guaranteed path forward — private, anonymous, and life-changing.
Why Nothing Else Exists Like This
30 Years of Direct Practice Cannot Be Replicated
ANXAPP was built on 180,000+ resolved cases and three decades of unbroken observation — refined across every culture and healthcare system. No university, pharmaceutical company, or mental health technology platform has produced a comparable tool, because none possesses the longitudinal clinical depth required to build one.
The assessment identifies not current symptoms, but the stable neurological and behavioural architecture that precedes anxiety condition onset. It is the only technology on earth capable of answering the question that matters most: is this person at genuine risk of developing an anxiety condition?
And unlike any other mental health tool, the score does not stand alone. Every result connects directly to TRT Therapy — the Linden Method — with over 650,000 documented full recoveries. Identify the predisposition. Implement prevention. Access recovery. Outcomes guaranteed.
