Introducing the Phase Calendar Extension
Planning your life inline with your cycle
What if your calendar didn’t just organize your time, but actually helped you optimize it based on how you’re really feeling? Welcome to the new Phase calendar extension: a groundbreaking way to organise your work, based on your biology.
If you’ve ever thought, “Why did I schedule that presentation today?” or felt completely out of sync with your to-do list, this is the feature for you.
Your energy, confidence, and cognition naturally change across your cycle. Phase now brings that insight straight to your calendar, so that you can plan your work, life and schedule in line with your changing strengths. And as many of our Beta users have shared, the calendar integration is their favourite feature!
“OBSESSED with the new calendar integration. It’s exactly what I wanted and it’s helping so much. Just that snapshot view, it’s been such a huge help in figuring out my month, meetings, and work schedule.”
The verdict? This extension is more than an add-on, it is the tool that sets Phase apart. For the majority of our Beta users, it is the most useful feature, and why they love Phase.
So what is the Phase calendar integration? How does it work, and how can you use it alongside many of the other smart calendar tools out there?
How the Phase Calendar Integration works
Something we know to be true is that behaviour change isn’t just about education, it’s about helping you build new habits. That’s why Phase integrates directly into the work tools you're already using, starting with your Google Calendar.
When you install the Phase calendar extension, you’ll:
See a simple overlay of your current cycle and which phase you are in, directly on your calendar.
Use the integration to toggle on or off your cognitive element(s), to see when your energy, cognition, focus, reflection, creativity or communication are peaking. View this in daily, weekly or monthly view. Use this information to plan your work to meet your strengths.
Get contextual prompts within a meeting invite when scheduling meetings or big tasks: Think "Your estrogen is rising - this is a great day for brainstorming or leading that workshop."
Sense-check your schedule: Not sure whether to push that 1:1 back a few days? Phase will let you know when you're likely to be more focused or emotionally attuned.
100% private, for your eyes only.
Initially available in Google Calendar, Microsoft Outlook is coming soon. This smart overlay turns your natural hormonal rhythm into an actual productivity strategy.
“The calendar integration is my favorite feature of Phase - I love being able to quickly see what my energy is doing this week and next.”
Why This Is So Powerful
We designed this feature because we saw a gap: the best productivity tools help manage your time, but they rarely help you manage your energy.
That’s what sets Phase apart.
And if you’re someone who already uses powerful calendar tools, you’ll love how Phase plays nicely with them. Here are a few of our favorites that complement the Phase integration beautifully:
1.Reclaim.ai – Smart Scheduling with Priorities & Habits
Automatically blocks time for deep work, workouts, or admin tasks
Moves events dynamically based on shifting priorities
Great for: Habit stacking and real-time flexibility
2. Clockwise – AI-Powered Focus Time
Minimizes context-switching by creating focus blocks
Reschedules meetings to reduce fragmentation
Great for: Team alignment and solo deep work
3. Motion – AI Daily Planner
Combines tasks, meetings, and breaks in one schedule
Uses AI to rearrange your day when priorities shift
Great for: Anyone wanting a "set it and forget it" workflow
4. Sunsama – Mindful Daily Planning
Pulls tasks from multiple tools like Asana and Trello
Encourages intention in daily planning
Great for: Burnout prevention and balance
The Phase Difference
While many of these tools tap into productivity through automation, focus, or flow, none of them consider the biological cycle that shapes your energy, mood, and motivation. Phase doesn’t replace your favorite tools, we supercharge them.
By layering Phase on top of Motion, Sunsama, or Reclaim, you add a deeply personal lens: your hormonal data becomes part of your planning toolkit. That means fewer burnouts, better meetings, and more wins.
And while tools like Timeshifter acknowledge biological rhythms like sleep or travel, they stop short of calendar-native insights, working as an app that is separate to how you manage your life day to day. Phase goes the distance, providing you with the information that you need, right inside your work week.
