The reality
Your energy & focus shifts. Your wearables can tell you why.
Our ability to focus shifts hourly, daily, weekly leading to frustration & guilt. Your trackers follow your sleep, recovery, HRV, and cycle. Science proves this data can predict your energy, and how your brain will perform today.
The problem
Different types of work thrive in different mental states.
Some work needs high-energy collaboration. Some suit quiet reflection or systematic attention. Some require creativity peaks. Success comes from doing the right work at the right time.
The solution
Phase connects your bio data and work for a more productive day.
We read your sleep and cycle data, look at your existing tasks and calendar, and help you organise your work so it's best aligned to your energy and focus today.
Translate your wearable data into performance at work.
1
Connect your wearables or apps.
Phase pulls live bio data from Oura, Whoop, Apple Health, Garmin, Flo, and 70+ other wearables and apps, including your sleep score, readiness, HRV, recovery, and cycle phase.
2
Bring in what you're already working on.
Phase syncs your tasks and calendar from the tools you already use, and assesses them based on whether they need high-energy collaboration, quiet reflection, or systematic attention.
3
Phase helps you optimize your day.
Phase acts like an executive assistant that also understands your biology and your brain, showing you what to work on now and how to plan your time.
Phase works with the tasks and events that you can flex. Whilst some work is non-negotiable, making the most of every day is in our control.

Built with our scientific advisors, informed by frontier research.
Our scientific advisors are leading minds in neuroendocrinology, sleep science, and women's health. Our algorithm draws on peer-reviewed research into hormones, sleep, and cognition, and translates it into a daily alignment score that maps to your tasks and calendar.
Your bio data stays yours. We don't sell it, we don't train models on it, and you can disconnect anything, any time.

What our Beta users say
★★★★★
"I've worn an Oura ring for three years. It tells me my sleep score is 58. So what? Phase is the first thing that actually does something with that number, and I can now organise my work around my actual energy."
Daniel K.
Senior Consultant
★★★★★
"I've been using Notion, Google Calendar and Whoop but none of them talked. Phase is the layer that connects them and tells me what to do with the day in front of me. Knowing exactly where to start has been a game changer."
Alex M.
Founder, early-stage startup
★★★★★
"I spent a decade forcing myself into the same eight productive hours every day. My luteal days now run on quality control and deep focus, which turns out to be when I do my best work anyway. First tool that's made me feel like a high performer instead of a guilty one."
