How Nadi Connects Your Menstrual Cycle to How You Feel, Live and Work

Nadi treats your menstrual cycle as a foundation for how you feel, live and plan — then puts it where you already look every day: your Google or Apple calendar. Instead of asking you to open another app, it shows your four phases (follicular, ovulatory, luteal, and the menstrual phase implied by the cycle) directly in the calendar you already use, so cycle awareness becomes part of your existing routine rather than a separate task. It is currently in beta, with an early-user sign-up and a waitlist.

What Nadi actually does

Two things sit at the centre of the product:

• For you: your four cycle phases appear in your Google or Apple calendar, so you can see how your cycle shapes how you feel, live and work and plan around it day to day.
• For workplaces: a free self-assessment based on BS ISO 45010 (ISO 45010:2026) — 12 questions across six areas, taking about 3 minutes — plus a time-boxed "Nadi Workplace Cohort" pilot aimed at helping experienced women keep doing their best work.

The core idea is "Understand. Integrate. Take action." You first understand your cycle, then integrate it into the calendar you already plan in, then act on it.

How the cycle maps onto your calendar

Nadi places your phases as an overlay on a normal week view. In the example shown on the site, a month grid carries ordinary commitments — standup, design review, school run, deep work, board meeting, long run, family lunch — while the phases (follicular, ovulatory, luteal) run underneath them.

That matters because the calendar is where planning decisions actually happen. If you can see you are in a luteal stretch during a heavy delivery week, you can move deep work, protect recovery time, or flag a lighter meeting load before the week starts — rather than noticing after the fact.

Why calendar-native beats another app

One early user, Emily, a writer and director, put it plainly: "I love that it doesn't require yet another app — syncing with your current calendar is such a brilliantly simple idea!" The practical benefit is that you do not have to remember to check a second tool; the context arrives inside the schedule you are already editing.

What early users say they want from it

The testimonials on the site cluster around one theme: structuring work around energy rather than pretending energy is constant.

• Laurence, a career coach, described manually blocking a "slow down week" in Outlook before her period while working in banking, and noted it would be "so much better if this can be automated."
• Steph, in marketing, framed it as empowering people to "structure their days, weeks and months in a way that actually gets the best outcomes for everyone involved — the business included."
• Jess, a wellbeing practitioner, and others signed up specifically to see it launch.

These are early-user reactions rather than verified outcomes, so treat them as signals of intent, not evidence of results.

The workplace side

Nadi's workplace offering starts with a free scorecard: "How menstrual cycle-aware is your workplace?" It is built around BS ISO 45010 (ISO 45010:2026), runs to 12 questions across six areas, and returns a score plus practical next steps in about 3 minutes. From there, organisations can run a Nadi Workplace Cohort — described as a time-boxed pilot.

If you are evaluating this for an employer, the sequence is: take the free self-assessment first, then decide whether a cohort pilot is worth scoping.

What to check before you commit

• Platform coverage: the site states Google Calendar and Apple Calendar. If you plan in something else, confirm support before relying on it.
• Stage: the product is labelled Beta, so expect change.
• Access: joining is framed as becoming an early user or joining a waitlist — availability may be staged.
• Pricing: the site references subscribing, but no prices or payment details are published, so cost is not something you can assume either way.

The short version

Nadi's proposition is narrow and clear: understand your four cycle phases, see them inside the calendar you already plan in, and use that to shape how you feel, live and work. The workplace scorecard is free and takes about 3 minutes; the personal product is in beta with early-user sign-up. If "another app to check" has been the reason cycle tracking never stuck for you, the calendar-native approach is the part worth testing.
