Why Momentum Exists
The problem I couldn't solve—until I did.
I've spent 20 years helping people change their health behaviors. Public health degrees. National psychological programs. International healthcare systems. I know what works on paper.
But here's the uncomfortable truth: knowledge isn't enough.
You can know exactly what you should do and still not do it. You can have all the tools, all the plans, all the motivation talks—and still feel like you're running on a treadmill going nowhere.
I know this because it happened to me.
The Gap Between Knowing and Doing
On paper, my life looked good. Good job. Achievements unlocked. Boxes ticked.
But I felt hollow. Drained. Like I was living someone else's checklist.
The disconnect wasn't that I didn't know what to do. It was that what I was doing had no connection to what actually mattered to me.
I had all the knowledge. I had the expertise. I had the to-do lists. I had the vision of what good looked like. But something fundamental was missing.
The Journey Inward
That gap—between knowing and doing, between busy and meaningful—sent me looking for answers.
I dove into Buddhism. Philosophy. I got curious about how my mind actually works, not how it's supposed to work.
What I found wasn't a magic formula. It was a simple, ancient idea that changed everything:
Eudaimonia.
The ancient Greeks didn't see a good life as one full of pleasure (though it can include pleasure). They saw it as a life lived through your values—where your daily actions align with what you truly care about.
Not what you should care about. What you actually care about.
The Thread That Changes Everything
Once I sat down and asked myself what I truly valued—not in a corporate workshop way, but in a "what would I regret not doing" way—everything clicked.
I realized I was doing things aligned with my values. I just hadn't seen the thread connecting them.
And to-do lists don't give you that thread. They just give you more boxes to tick.
When I connected my daily actions to my values, everything shifted:
- Tasks stopped feeling like obligations and started feeling like choices
- "I have to" became "I want to"
- Progress stopped being about discipline and started being about direction
People started telling me how disciplined I'd become. I didn't understand what they were talking about—I wasn't trying harder. I was just finally moving in a direction that mattered to me.
The Results That Made Me Build This
I didn't just theorize about this. I lived it.
saved toward my emergency fund (on track to £10,000)
of credit card debt paid down (from £22,000)
body fat achieved through sustainable habits, not crash diets
time with friends and family—not "someday," but scheduled
All of these things became a joy because they added to my life. They weren't just tasks to be done.
Why I Built Momentum
Here's the problem: I'm a product manager with AI tools at my fingertips. I could build this system for myself.
But most people can't.
Most people don't have 20 years of behavior change experience. They don't have the time to build custom systems. They just want to stop feeling stuck.
So I built Momentum.
Not as another productivity app. Not as another to-do list with better colors.
As a way to connect what you do each day to what you actually care about.
What Makes Momentum Different
1. It Starts With Values, Not Tasks
Most apps ask: "What do you need to do?"
Momentum asks: "What matters to you?"
Because once you know that, the doing becomes obvious.
2. It's a Coach, Not a Checklist
Your AI coach doesn't just track what you do. It helps you think through why you do it, spot patterns in your thinking, and challenge the habits holding you back.
It's the conversation I wish I'd had with myself years ago.
3. It Builds Momentum Through Micro-Steps
Big goals are paralyzing. "Build an emergency fund" feels impossible.
"Set up a direct debit into my emergency fund for the day after I'm paid" is simple and easy.
Momentum breaks down your values into daily actions—small enough to do, meaningful enough to matter.
4. It's Private By Design
I built this because I needed it, and privacy is important to me. So I built this so that I know my data doesn't go anywhere. The same is true for your data.
Your conversations stay on your device or encrypted in your iCloud account. No email required. No tracking. No ads.
Your growth journey is yours alone.
The Philosophy Behind It All
Momentum isn't built on hustle culture or "optimize your morning routine" advice.
It's built on eudaimonia—the idea that a good life is a life lived through your values.
That means:
- Progress isn't about doing more; it's about doing what matters
- Motivation isn't about discipline; it's about direction
- Success isn't about ticking boxes; it's about feeling aligned
What I've Learned
After 20 years in behavior change, Buddhism, philosophy, and building this app, here's what I know:
You already know what works for you.
You don't need someone to tell you what your values should be. You don't need another expert's framework.
You need support in putting what matters front and center. You need a way to connect your daily actions to the life you actually want.
That's what Momentum does.
This Is Still a Journey
I don't claim to have all the answers. I don't think there's one perfect system for everyone.
What I do know is this: when you connect your daily actions to your values, everything changes.
I've lived it. I've built it. And now I'm curious to see where it goes—together with people who are ready to stop planning someday and start building today.
Join Me
Momentum isn't finished. It's evolving as I learn what people need, what works, and what doesn't.
If you're feeling that gap between knowing and doing—between busy and meaningful—I'd love for you to try it.
Not because I have all the answers. But because I think you do.
You just need a way to see them clearly.

Download MomentumAbout Todd
I've been chasing the answer to behavior change for 20 years.
I've co-founded startups. Won awards from the UK government and Royal Society for Public Health. Earned degrees in nutrition, public health, data science, and AI. Worked across healthcare systems from genomics to mental health to chronic disease.
All of it taught me what works on paper.
None of it taught me how to close the gap between knowing and doing—until I turned inward and asked what I actually valued.
Now I'm building Momentum because I believe everyone can make the same connection. Everyone is an expert in themselves.
This is personal. And it works.
