About Mary Double O
Practical tools for clearer business, money and everyday life.
The thinking behind every product in the shop — and why each one has to earn its place there.
Hi, I'm Mary Owie
I'm a product designer, product manager, mother and storyteller creating thoughtful digital tools for freelancers, small-business owners and families.
Every product I make starts the same way: with a real problem I've either lived through myself or watched someone close to me struggle with — a bedtime routine that never quite lands, a budget that falls apart by week two, or a small business owner unsure if their pricing actually covers their costs.
Every product is built to solve a real problem, simplify the next step and help you move forward with greater clarity and confidence. That's the standard everything here has to meet before it goes in the shop.
How I work
Built from real problems
Every product starts with something real — mine, or something I've watched someone close to me struggle with.
Simple over clever
If it needs a manual to understand, it isn't finished yet. Everything here should make sense on the first try.
Made to be used
Not another tab to open and forget. Every product is built to fit into a routine you'll actually keep.
