Monthly Rose
Blooming on time, every month
Monthly Rose is a clean, ad-free period tracker. It predicts your next period and fertile window, reminds you at the times you choose, and turns your records into patterns you can actually read.
No ads, no third-party analytics
No account? Records stay on your phone
Reminders that explain themselves
What's inside
What to log today, when your next period is due and what your body has been doing, all on one screen.
Today
Period and fertile window predictions that learn
See period days, the predicted range, the fertile window and ovulation on a full-month calendar. Tap any day to log it; a new period fills in your usual number of days.
- Recent cycles weigh more; with only a few cycles logged, typical cycles help fill the gap, and you can see how many days off recent predictions were
- Cervical mucus, ovulation tests and basal body temperature combine into a day-by-day fertility estimate
- Log flow, symptoms, mood and sex in one tap, or just tell the AI assistant in a sentence
Health
Understand your own patterns
Monthly Rose looks at your records and watch data together: how sleep, heart rate and wrist temperature change by phase, and which symptoms keep showing up before your period.
- "Your patterns": how much less you sleep and how much higher your resting heart rate is in the luteal phase, in your own numbers
- Recurring symptoms are folded into your "period soon" reminder, days ahead
- A short report at the end of every cycle, and a one-page summary to bring to your doctor
Talk
Rosie, an AI wellbeing coach who's always there
Feelings, relationships, stress: say whatever is on your mind. Rosie takes your current phase and recent mood into account, and you can call her, too.
- Only a de-identified summary (phase, mood, sleep statistics) goes to the AI, with no dates or anything that identifies you
- AI-generated content is always labeled; Rosie is an AI and cannot replace professional help
- If you mention wanting to hurt yourself, she shows crisis helplines for your region first
Circle
Talk with people going through the same thing
Periods, trying to conceive, pregnancy and postpartum: share experiences with real people under a random nickname. None of your cycle records ever go into the Circle.
- An anonymous question of the day; results show only once enough people have voted
- Every post and comment can be reported or blocked, with community rules and human review
- No recommendation algorithm, no ads, no direct messages
Four modes for every stage
Switching modes only changes the home screen, reminders and what the AI focuses on. All your records stay, and you can switch back any time.
Period
Next-period predictions, flow, cramps and mood, with a heads-up before your period starts.
Trying to conceive
Fertile window and ovulation, BBT, cervical mucus, and ovulation tests read from a photo.
Pregnancy
Weeks and due date, a weight-gain range from published guidelines, checkup schedule, kick counter and contraction timer.
Postpartum
Weeks since birth, the 6-week checkup, lochia, pelvic floor training and a mood check-in.
More features
Everything that can be worked out on your phone is worked out on your phone, and every reminder is decided by on-device rules.
Medication reminders
Daily, on certain cycle days or as needed. Tap "Taken" right on the notification and see how often you're on time.
Ovulation test reader
Snap a photo of an ovulation test to read the C and T lines. Nothing is logged until you confirm.
Doctor summary
Your recent cycles, symptoms and notes on a one-page PDF to show your doctor.
Partner sharing
Choose exactly what to share; your partner scans a code to see how you're doing. Stop sharing any time.
On your wrist
Apple Watch and Wear OS: check your status at a glance, log quickly, or say a word to Rosie.
Apple Health sync
On iPhone, periods, symptoms, temperature and weight sync both ways with Apple Health, plus sleep, heart rate and wrist temperature from your watch.
Widgets & Live Activities
Home Screen and Lock Screen widgets and the Dynamic Island, discreet by default: they never say "period".
App lock
Lock Monthly Rose with Face ID, fingerprint or passcode; content is hidden in the app switcher, too.
Your records belong to you
Period and pregnancy data is some of the most private data there is. Monthly Rose is designed to keep it in your hands.
Only on your phone without an account
Every logging feature works without an account. Photos in your records and your watch's heart rate and sleep data stay on your phone.
No ads, no third-party analytics
There is no ad space in the app, and no third-party analytics, advertising or crash-reporting SDKs.
Encrypted backup when you sign in
Once you sign in, records are encrypted entry by entry and backed up, so you can restore them on a new phone. Without an account, nothing is uploaded.
Export, delete, leave any time
Me → Settings → Your data: export everything, delete all your data or delete your account in one tap.

Frequently asked questions
How much does Monthly Rose cost?
Monthly Rose is free to download. If you download it from the App Store or Google Play outside mainland China, you can use everything free for 7 days; after that it needs a Basic membership of $5.99 per month. Plus (AI insights, unlimited Talk and voice calls with Rosie) is an optional add-on. In mainland China, logging, predictions and reminders are free.
Where is my period data stored?
Without an account, they stay only on your phone (on iPhone they can also sync both ways with Apple Health), and every logging feature still works. Once you sign in, your records are encrypted entry by entry and backed up so you can restore them on a new phone. Photos in your records and your watch's heart rate and sleep data stay on your phone. There are no ads and no third-party analytics SDKs.
Can I use the fertile window for birth control?
No. The fertile window and ovulation day are estimates based on your records. They help you understand your cycle but are not a method of contraception. Monthly Rose shows how many days off its recent predictions were, and it gets more accurate the more you log.
Which devices does Monthly Rose support?
iPhone, iPad and Apple Watch (App Store), and Android phones and Wear OS watches (Google Play). The app is available in English, Simplified Chinese and Traditional Chinese and follows your system language.
Who is Rosie?
Rosie is the AI wellbeing coach in the Talk tab. She takes your cycle phase and recent mood into account, and you can also call her. Only a de-identified summary is sent to the AI, and AI-generated content is always labeled. Rosie is an AI and cannot replace professional help; if you mention wanting to hurt yourself, she shows crisis helplines for your region right away.
How do I export or delete my data, or delete my account?
Go to Me → Settings → Your data. You can export everything (CSV / JSON), delete all your data, or delete your account in one tap.
