Halo Design
We design AI apps that help people.
Small, careful apps that do one useful job well — and are honest about what they know. We start with something we care about: getting people to the start line fitter, without guesswork.
Our apps
Private beta iPhone
Closed Loop
An AI running coach for iPhone. It builds your plan to race day, reads what actually happened from your watch and strap, and re-plans every week from reality.
How we build
Useful, plain, and honest.
Built on your real data
Our apps work from what actually happened, not from what a plan assumed. When the data changes, the advice changes.
Plain language
No jargon and no dashboards for their own sake. A clear answer, and the reason behind it.
Honest about limits
When something is out of reach, we say so — with the numbers. You stay in charge of every decision.
