What is Nadi?
Nadi is a menstrual cycle–tracking tool that works inside the calendar you already use. Rather than asking you to open a separate app, it maps your four cycle phases — follicular, ovulatory, luteal and menstrual — onto your existing Google or Apple calendar, so your energy patterns sit alongside your meetings, workouts and social plans. The idea is to treat your cycle as a foundation for how you feel, live and plan, not as a separate health chore.
It has two sides:
- For individuals: your phases appear in your day-to-day calendar, so you can see at a glance when to schedule demanding work, rest or social commitments. It is currently in beta, with early users invited to join.
- For workplaces: a free self-assessment scorecard based on BS ISO 45010, framed around the question "How menstrual cycle-aware is your workplace?" It covers 12 questions across six areas and offers practical next steps. There is also a Nadi Workplace Cohort, described as a time-boxed pilot aimed at helping experienced women keep doing their best work.
A practical way to judge whether it fits you: if you already live in Google Calendar or Apple Calendar and have tried cycle apps but abandoned them because they were one more place to check, the calendar-native approach is the main draw. If you want detailed symptom logging, medical tracking or fertility-focused charting, that is a different job — Nadi's pitch is planning and awareness, not clinical tracking. Its own page stresses "Your cycle. Your data." and "Understand. Integrate. Take action." as the sequence.
For a workplace angle, the free scorecard is the low-commitment first step: three minutes, no pilot required, and it gives you a concrete score to decide whether a cohort pilot is worth proposing to a manager or HR lead. You can start there at Nadi.
How does Nadi sync my menstrual cycle phases with Google or Apple Calendar?
Nadi puts your four menstrual cycle phases into the Google or Apple calendar you already use, so cycle awareness shows up alongside your existing events rather than in a separate app. The page describes the phases appearing in your calendar (a beta feature), with the stated goal of helping you see how your cycle shapes how you feel, live and work — and to plan day to day around it.
What that looks like in practice
- Your calendar gains phase information across the month — the page shows Follicular, Ovulatory and Luteal phases laid over a normal week of standups, 1:1s, deep work and social plans.
- Because it lives in Google or Apple Calendar, you keep one place for planning: no second app to check, and no need to re-enter events.
- The intended benefit is planning, not just tracking: you can compare demanding days (board meetings, demos, travel) against where you are in your cycle and adjust.
What the page does not spell out The exact mechanics — which calendar account you connect, whether phases appear as all-day events or a separate calendar layer, how to edit or remove them, and how syncing is set up — are not detailed in the supplied page evidence. Treat those as things to confirm before relying on it.
A practical way to decide If your main problem is that cycle tracking lives in an app you forget to open, calendar-based phases solve that directly. If your main problem is detailed symptom logging or clinical insight, a dedicated tracker may still be the better fit — Nadi's pitch is integration into planning, not depth of tracking.
Next step Use the beta as a low-effort test: add your cycle to your calendar, then look back after one full month and ask whether seeing the phases actually changed a scheduling decision. That is a more useful signal than whether the idea sounds appealing. For context on the wider category, see Clue and Flo.
How can I assess whether my workplace is menstrual cycle-aware?
Start with the free self-assessment Nadi already publishes: it describes a workplace scorecard based on BS ISO 45010, made up of 12 questions across six areas, taking about three minutes. That gives you a score and suggested next steps, which is a reasonable first benchmark before you decide whether a deeper pilot is worth running. You can find it at Nadi.
H3 What the scorecard is actually for
It is a conversation starter and a gap-finder, not an audit. Its value is that it turns a vague question — "are we cycle-aware?" — into a small set of answerable items you can put in front of HR, a line manager or a wellbeing lead. Use the score as a baseline, then repeat it after any changes so you can see movement rather than argue about impressions.
H3 A practical way to run the assessment
- Answer honestly as an individual first, then ask two or three colleagues in different roles and life stages to do the same independently.
- Compare answers. Divergence between a manager and an employee, or between someone with a straightforward cycle and someone with endometriosis or perimenopause, is the most useful signal you will get.
- Pick the two lowest-scoring areas and turn each into one concrete change — for example, flexible start times during a difficult phase, or a norm that "slow down week" placeholders are respected rather than questioned.
- Set a review date and re-score.
H3 What a cycle-aware workplace looks like in practice
- Policy: menstrual and menopause symptoms are named in sickness, flexible-working and wellbeing policies, rather than folded into generic "health".
- Planning: people can block or mark lower-capacity periods without disclosing medical detail, and managers treat those blocks as real commitments.
- Meetings and travel: no assumption that everyone is equally capable of an early flight, a late dinner or a back-to-back day.
- Managers: trained to have the conversation without prying, and to route people to occupational health or a GP when clinical help is needed.
- Data: any cycle tracking stays private to the individual. Nadi's own framing is "your cycle, your data", which is the standard to hold any tool to.
H3 Where Nadi's workplace offer fits
For organisations, Nadi describes two routes: the free scorecard, and a Nadi Workplace Cohort — a time-boxed pilot aimed at helping experienced women keep doing their best work. The individual side puts your four cycle phases into the Google or Apple calendar you already use, currently in beta. The trade-off is deliberate: no separate app to check, but it depends on your calendar being the place you actually plan, and on you being comfortable with cycle information sitting alongside work events. If your workplace uses locked-down or shared calendars, that is a real constraint worth testing before committing a cohort.
H3 If you want a second opinion
The scorecard is self-reported, so pair it with something external. ISO 45010 is the standard Nadi cites; the official ISO pages at ISO will tell you what the standard covers and whether certification is realistic for your size of organisation. For the health side of the conversation, ACAS publishes free, practical guidance on managing health at work and having sensitive conversations, which is useful for briefing managers who are nervous about the topic.
H3 Decision criterion
If you mainly want to know where you stand and start a conversation, the free scorecard is enough. If you want to change how a team actually plans its weeks, the cohort-style pilot is the more meaningful test — but only if you can guarantee privacy and get at least one senior sponsor who will model using it.
What is a Nadi Workplace Cohort and how does it work?
A Nadi Workplace Cohort is a time-boxed pilot programme offered by Nadi for employers. According to the site, it is aimed at helping experienced women keep doing their best work, and it sits alongside a free self-assessment: the BS ISO 45010 workplace scorecard (12 questions across six areas).
How it works, based on the page evidence
- A workplace signs up for a fixed-length pilot rather than an open-ended benefit.
- The focus is on integrating menstrual cycle awareness into working life — not just offering information.
- Nadi frames the approach in three steps: Understand, Integrate, Take action.
- The individual side of the product syncs a user's four cycle phases into the Google or Apple calendar they already use, so a cohort would likely build on that day-to-day habit. The page describes this individual feature as in beta; it does not spell out exactly how cohort sessions are scheduled or priced.
Who it suits
- People- or HR-led teams that want a small, bounded trial before committing to a broader wellbeing programme.
- Organisations with many experienced women in mid-career or senior roles, where cycle-related energy shifts can collide with demanding schedules.
- Employers that prefer a lightweight tool layered onto existing calendars over another standalone app — a point several early users made, such as Emily, a writer and director, who welcomed not needing "yet another app."
Trade-offs to weigh A time-boxed cohort gives you a clear start and end, which makes it easier to evaluate than an annual platform contract. But the page does not detail session length, facilitator involvement, group size or success measures, so those are questions to ask before committing. The free scorecard is the lower-risk first step: it gives you a baseline and practical next steps in about three minutes.
Next step Start with the free workplace scorecard to see how cycle-aware your organisation currently is, then decide whether a cohort pilot is worth running. If you are an individual rather than an employer, the relevant route is becoming an early user and adding your cycle to your existing calendar. You can explore both at Nadi.
How does Nadi protect my menstrual cycle data?
Nadi's page doesn't publish a detailed data-protection policy, so the honest answer is: the site says "Your cycle. Your data." and emphasises that your four phases appear in the Google or Apple calendar you already use, but it doesn't spell out encryption, retention or sharing practices. Treat that as a question to ask before you sign up, not as a guarantee.
What the page does tell you, and why it matters:
- Your cycle information is delivered into a calendar you already control, rather than only inside a separate Nadi app. That means the entries live in your Google or Apple account and are covered by those providers' security and sharing settings — which you can inspect today.
- Because calendar entries can sync to shared calendars, work accounts or family devices, the practical privacy risk often sits in your calendar setup, not in Nadi itself. Check which calendars are shared before adding anything sensitive.
- The workplace side is a free self-assessment based on BS ISO 45010 and a "Nadi Workplace Cohort" pilot. If you take part through an employer, ask whether individual cycle data is ever visible to managers or HR, and get the answer in writing.
A useful next step: before joining, email Nadi and ask three specific things — where data is stored, whether it is ever shared with employers or third parties, and how you delete it. Compare that with the privacy policies of the calendar you'd use, such as Google or Apple. If cycle tracking at work is your focus, the free scorecard is the low-risk entry point because it asks about workplace practice rather than your personal cycle.
Can Nadi help me plan work tasks around my cycle phases?
Yes. Nadi is built around exactly that idea: it maps your four cycle phases into the Google or Apple calendar you already use, so planning happens where your work and personal commitments already live rather than in a separate app. Its stated aim is to help you understand how your cycle shapes how you feel, live and work — then act on it day to day.
The practical value depends on what you want from it:
- Awareness while scheduling. Seeing phase markers next to meetings and deadlines helps you notice patterns, such as consistently heavy weeks landing in your luteal phase.
- Deliberate task shaping. You can shift demanding work (presentations, negotiations, deep-focus blocks) toward phases where you tend to have more energy, and protect lighter days for admin and recovery.
- Less friction. Because it sits in your existing calendar, there is no second tool to check or maintain.
H3: What it does not do for you The product supplies the phase context; it does not decide which tasks to move. That judgement is yours, and it works best once you have tracked a cycle or two and can see your own patterns rather than assuming a generic template. Treat phase-based planning as a hypothesis to test, not a rule — sleep, workload and health often matter more than phase on any given day.
H3: A concrete way to start Pick one recurring commitment that drains you, note which phase it falls in this month, and try moving or resourcing it differently next cycle. Keep a short note of what changed. If you want to plan around your cycle at work rather than alone, Nadi also offers a free workplace self-assessment scorecard and a time-boxed Workplace Cohort pilot aimed at helping experienced women sustain their best work — see Nadi.
If your main goal is personal task planning, the calendar sync is the feature to trial first. If your goal is team-level change, the workplace scorecard is the more relevant entry point.
