Description by KeiK LLC Written by the developer, not by AppBrain. Click to read.
Wish your partner just knew when it's one of those days? This is the period calendar made for two. Great for boyfriends, husbands and any partner.

You log your period and mood as usual. Your PMS week, today's mood and a quick request reach your partner's phone. When they see your request, you'll know, so nothing goes unheard. Kindness arrives before the argument does.

CONNECT WITH ONE QR CODE, WHATEVER PHONE THEY USE
1. Choose "I'll track" and show the QR code on your screen, or send the invite link
2. Your partner installs the app and scans the code or opens the link
3. Keep logging as usual, and how you're doing shows up on their phone
No account needed. You can also connect later. Pick what to call them, too: boyfriend, husband, girlfriend, wife, partner or a nickname.

WHAT YOUR PARTNER SEES
• Where you are in your cycle (PMS week, on your period, days until your period) and a 2-week forecast
• Today's mood (happy, okay, uneasy or irritated)
• A quick request: "I'd love something sweet", "I need some space", "I need a hug", "Something warm to drink, please", "Could you get me painkillers?", "I want an early night", "Please just listen", "Thank you for everything"
• Today's symptoms, like cramps or headache
• A heads-up on the morning your PMS week starts, and when your period starts
You can turn off each item one by one, and stop sharing anytime.

NEW: FERTILE WINDOW ESTIMATES
Based on your period log, the calendar and home screen show an estimated fertile window. A relatively low-chance window is shown only when you have logged at least 3 periods and your cycle is regular. You decide whether to share it with your partner (off by default).
Note: these are estimates only and cannot be used as a method of contraception.

EVERYTHING YOU NEED FOR YOURSELF
• Period log and next period prediction
• Cycle phases: menstrual, follicular, ovulation, luteal and PMS
• One-tap mood logging, with causes and notes
• 12 symptoms: headache, cramps, back pain, bloating, breast tenderness, fatigue, acne, insomnia, anxiety, nausea, cravings and mood swings
• Reminders before your PMS week and your expected period
• Calendar and stats to see how your cycle and mood connect
• Home screen widget
• 8 theme colors and dark mode
• Available in 35 languages

PRIVACY
Your records stay on your device. Only while you're connected, the items you choose pass through our server (Google Firebase) to reach your partner. We don't use your name or email, and we never send your notes or past records. When you stop sharing, the data on the server is deleted.

PMS mood swings aren't your fault. You don't have to handle them alone.
