Know what she needs, before she has to ask.
The period tracker for men who want to actually understand her cycle — not guess.
Daily, phase-aware guidance for supporting your partner through her cycle — what to do, what to avoid, and why.
100% offline. Nothing ever leaves your phone.
Built for men who want to show up better.
For the husband who wants to help but doesn’t know how
You care, but reading the room is hard. PartnerCue translates where your wife is in her cycle into plain, specific things you can actually do today.
For the long-distance boyfriend
Can’t be there in person? A quiet daily nudge still helps — the right text, the right check-in, sent at the right moment.
For planning around her cycle, minus the awkward conversation
Skip the guesswork before a trip with your girlfriend, a big date, or a tough week at work. Know what’s coming without having to ask.
Her cycle data is sensitive. We built PartnerCue so it never has to leave your phone.
No accounts
Nothing to sign up for and nothing tied to your identity or hers.
On-device encryption
Every entry is protected with AES-256-GCM via your device's secure Keystore or Keychain.
Zero analytics, zero servers
PartnerCue can't phone home about her cycle — there's nowhere for it to phone.
Everything you need, nothing you have to figure out.
Her current phase, at a glance
A single wheel shows the Menstrual, Follicular, Ovulatory, and Luteal phases, where she is today, and what tends to shift — from energy and libido to how she's likely feeling.
- Drag or tap any point on the wheel to preview that phase
- Log period start/end in two taps
- Plain-language context, not clinical jargon
Actionable do's and don'ts, not vague advice
Every phase comes with a specific, filterable list of things to do today — and things to skip — organized by category like communication, dates, and quality time.
- Browse by category: communication, dates, intimacy, and more
- Short, specific actions you can actually take
- Add your own custom tips over time
Her cycle history, always at hand
A full monthly calendar marks period days and fertile windows, with a running timeline underneath so you never have to reconstruct the last few months from memory.
- Color-coded period and ovulation/fertile windows
- Average period length and cycle length, calculated automatically
- Tap any day for that date's phase and notes
Specific gestures, with the reasoning behind them
Do's and don'ts aren't generic. Each one names the exact moment and explains why it lands — so the guidance turns into instinct instead of a script you're reading off your phone.
- "Celebrate a win out loud" — make a bigger deal of good news than she expects
- "Skip repeating last week's plan" — pick somewhere new instead of the usual go-to
- Expand into the full list of do's and don'ts for any phase, any time

Short answers about how PartnerCue works, what it costs, and how your partner's data stays private.
Is this app spying on my partner?
No. PartnerCue does not spy on anyone or connect to third-party accounts. It operates as a personal digital journal and local estimator where you enter key dates to stay mindful and supportive.
Does my partner need to install anything?
No. PartnerCue runs on your device alone. Your partner does not need to download an app, register an account, or share personal data.
Is my data private? Where is it stored?
Your data is completely private. PartnerCue is built offline-first—all entries are encrypted and stored strictly on your local device. No personal health information is uploaded to cloud servers.
What platforms are supported?
PartnerCue is available on both iOS and Android, with light, dark, and system theming.
Is PartnerCue free to use?
PartnerCue provides core cycle tracking, phase Ring views, and daily support tips for free, with optional premium upgrades for advanced notifications and custom guidance.
What is a period tracker for men?
A period tracker for men translates a partner's cycle into daily guidance — what phase she's likely in and what to do or avoid — instead of tracking symptoms the way apps built for the person having the cycle do. PartnerCue is built specifically around that use case.
How do I use PartnerCue?
Enter her last period start date and average cycle length — takes under a minute. From there, open the app any day to see her current phase and a short list of specific do's and don'ts for that day. No ongoing data entry required unless you want to log a new period start/end.
Is there a free period tracker for men?
Yes — PartnerCue's core phase tracking, predictions, and daily guidance are free. Multi-partner tracking and the expanded tip/article library are Pro features.
Can I track more than one partner?
Yes, PartnerCue Pro supports tracking multiple partners with separate cycle data for each.
Does PartnerCue send notifications?
Yes — you can enable phase-change alerts so you don't have to open the app to check. Notification timing is customizable on Pro.
Can I use a period tracker for multiple people?
Yes — PartnerCue Pro lets you use one period tracker for multiple people, each with their own separate cycle data and predictions.
