Why I Built Tilt
The personal story and six-domain framework that led to Tilt Your Life
Dr Justine Gatt
Neuroscientist · Founder
There's a particular kind of tired that doesn't show up on a to-do list. You can tick off everything you set out to do in a day — the meetings, the errands, the emails — and still end it feeling like something is missing. Not exhausted, exactly. Just... off.
I have experienced this in my own life on different occasions. One period in my life when I noticed this feeling was many years ago. On the surface, my life contained all of the good things – great career, happy family life, good friends. However, I remember sitting in work meetings, and the kind of work that normally would have brought me exhilaration was starting to feel wearing. I was going through the same motions but it didn’t bring the same joy as before. Something was amiss.
That feeling is what got me looking into wellbeing seriously — not as a buzzword, but as something worth actually understanding. And what I found, the more I read and the more I talked to people, was that most of what gets called "wellbeing advice" is either too vague to act on ("just prioritise self-care") or too narrow to be honest ("just get more sleep," "just exercise more"). Both miss something important: wellbeing isn't one thing. It's several things, and they don't move together.
You can be sleeping well and still feel like you're failing at everything. You can be smashing your goals at work and still feel disconnected from the people who matter to you. You can be calm on the outside and quietly falling apart on the inside. Any single measure of "how are you doing" flattens all of that into one number, and one number was never going to be enough.
Where the six domains came from
The deeper I got into the research — positive psychology, organisational behaviour, clinical work on stress and resilience — the more a pattern started to emerge. Wellbeing wasn't best understood as a single dial to turn up or down. It behaved more like a set of interconnected domains, each with its own logic, each capable of being strong even while another was struggling.
As a neuroscientist, I worked across the fields of psychology and psychiatry, I noticed wellbeing was being assessed in different ways or not assessed at all. What was needed was a multidimensional measure of wellbeing that could be explored across the fields, including one that could enable measurement of a closely related concept called resilience – the process of positive adaptation to adversity. So, I decided to create such a framework that captured the core components of wellbeing as well as resilience. I called this framework COMPAS-W.
That's where Composure, Own-worth, Mastery, Positivity, Achievement, and Satisfaction came from. Not as abstract categories borrowed from a textbook, but as an attempt to describe wellbeing the way it actually shows up in a person's week — sometimes steady, sometimes uneven, always more textured than a single score could capture.
Composure is about your emotional capacity to stay steady under pressure — not the absence of stress, but your relationship to it.
Own-worth is how you value yourself, independent of what you've achieved or how others see you.
Mastery is the sense of growth and competence when challenged — not perfection, but forward motion.
Positivity is the presence of real positive emotion – genuine, not performative – and not the suppression of everything negative.
Achievement is progress toward things that matter to you, distinct from busyness.
Satisfaction is contentment with what already is – your relationships, health, work life – not just what's next.
We validated the framework in thousands of adults, adolescents and children. We demonstrated its utility in the general population and in clinical samples, in men and women, in different cultures and countries, and in different ages – showing that languishing and flourishing states did not discriminate – it was present across them all.
But when we are talking about wellbeing in a specific person, it’s the detail that matters – the pattern across the wellbeing domains rather than their single score. Some people might be strong in some domains but quietly struggling in others, and most wellbeing tools have no way of showing that. That gap is the reason Tilt exists.
Why this matters to me
Knowing that we could measure wellbeing using this approach was important because it meant we can help people identify WHY they might feel off despite everything looking fine on the surface.
Back during those times in my life when everything seemed to be functioning well but something was missing, it would have helped me identify that the thing missing for me at that time was Mastery – I no longer felt challenged by the work I was doing. I couldn’t identify it at the time – I thought it might have been stress or a lack of positivity, but that was misguided. And I had reason to doubt that diagnosis, because despite reducing stress in my day or working on work that I loved, it was the sense of accomplishment around mastery of something new that was needed. If only I had taken my own COMPAS-W measurement!
And so now, I wanted to build an app that provides this clarity to others, quickly and simply. And I wanted the app to help guide the next few steps towards creating change. And that guidance might vary week to week, just as our life circumstances regularly shift as does our capacity for dealing with stress or being open to growth.
I didn't want to build another app that tells people to only breathe more or drink more water — not because those things are wrong, but because they're incomplete. I wanted to build something that reflects the actual complexity of being a person: uneven, shifting over time, made up of parts that don't always agree with each other.
That's what Tilt is trying to do. Not to fix you, and not to stop at a single score. Just to help you see the fuller picture of where you actually stand, so the next step you take is the right one for the part of your wellbeing that actually needs it.
This is the beginning of that story, not the end of it. But I wanted the first thing we published here to be honest about where it all started — with a feeling that didn't have a name yet, and a framework that eventually gave it one.
More soon .
