Use your wearable data to turn wasted days into productive ones.
You’ve built a great productivity system, but some days you achieve very little. Phase is the only planner that organises your tasks based on your sleep, HRV & cycle, so that you can surface the right work and stop losing afternoons, from day one.

No migration - see all your tools in one place
Keep the Google Calendar, Todoist, Notion, Linear or Asana set-up you’ve perfected, with zero migration and nothing new to maintain. Get a new perspective on your work day.
Most productivity tools assume you are the same person everyday.
We don't.
Do you have days when your set-up is perfect, but still nothing gets done?
Have you rebuilt or switched the task manager more than once, hoping for a more intuitive view?
Are you ending the day still feeling unaccomplished and not knowing why?

How it works
Immediately gain a new perspective on your productivity.
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.
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.

"Knowing exactly where to start has been a game changer"
Feedback from Beta users
★★★★★
"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."

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."
