Your menstrual cycle is impacting your productivity.

The 9-to-5 work pattern assumes consistent energy and productivity every day, forcing many women to follow the default 24-hour cycle and tackle all types of tasks daily.

However, research now shows us that menstrual cycles significantly impact energy, mood, and focus. Ignoring these natural rhythms leads to reduced productivity, increased stress, and burnout—costing individuals, companies, and economies billions. 

Changing hormones can become your superpower.

Science is helping us to better understand how our changing hormones enhance different skills throughout the month.

This knowledge can help us shift the work that is in our control to the phases of the month when we are going to be most efficient. In doing so, a women’s cycle becomes her super power.

Your future is forward syncing.

Phase will educate you about how your hormones impact your energy and cognitive abilities, with insights and task suggestions.

And then, with our seamless integrations, the product will support you day in, day out, to incorporate cycle-specific decision making into your workflows.

 Frequently Asked Questions

  • Phase is a ground-breaking productivity tool, built for women who want to align their work with their hormonal superpowers. Science shows that your brain and body operate differently across the phases of your menstrual cycle. By syncing your tasks with these natural shifts, Phase helps you work smarter, to improve productivity, reduce stress and avoid burnout.


    It’s more than an app—it’s an ecosystem. Phase integrates with tools like Google Calendar, Slack, and Chrome to keep you in sync wherever you work. Think of it as your secret weapon for optimising every single day. 

  • If you have a menstrual cycle and want to ditch the grind of one-size-fits-all productivity, Phase is for you. Whether you’re managing deadlines, big ideas, or just life in general, Phase helps you work with your body—not against it. Phase can be used by anyone with a menstrual cycle including those on most forms of contraception.

  • We’ve teamed up with scientists to crack the code of how your hormones shape six key areas of cognition — your energy, focus, reflection, communication, motivation, and creativity. Our algorithm translates this research into daily, actionable insights tailored to your cycle. It’s like having a data-driven coach in your pocket, which understands your natural rhythms and will support you to be your best. 

     Here’s how Phase is there to support you throughout your menstrual cycle: 

    • Daily radar charts show how your energy, focus, and creativity are shifting.

    • Task prompts suggest what to tackle (or avoid) each day.

    • Cycle-aware calendar views help you plan weeks ahead, scheduling tough tasks during your natural peaks.

    • Smart integrations with Google Calendar and Chrome keep you updated on where you are in your cycle—without interrupting your flow.

  • We keep it simple.  In the onboarding, we will ask you to tell us about your period history, including the first day of your last period and your average cycle length. Alternatively, you can sync this information from an existing period tracker, like Apple Health.  We’ll then use AI to predict your cycles going forward. If your cycle’s a little unpredictable, no problem—we’ll adapt as you log daily feedback. Think of it as a collaboration, not just another tracker.

  • Yes! When you register for Phase, we will ask you a series of onboarding questions, including whether or not you are using birth control, and if so, what type. Some types of contraception (e.g. condoms), won’t impact your natural hormonal shifts, others (like the pill), will. Once we know what type of contraception you are using (if any), we can adjust the algorithm to ensure that if you are taking additional hormones, the recommendations you receive are relevant for you.

  • At launch, Phase will integrate with Google Calendar to show where you’ll be in your cycle when planning meetings or deadlines—visible only to you (unless you want to share). Our Chrome extension ensures Phase has your back across your workspace.  


    Future integrations with Slack, Asana, and Microsoft Teams are coming. Got a request for an integration that you need? Let us know by contacting us!
