Know your partner's cycle and exactly how to show up each phase. Daily tips, gentle heads-ups before the shift, and an otter who never judges. Never drift apart.
Be the partner they brag about.
Otty is a couples period tracker and cycle tracker built for partners. Understand menstrual cycle timing, PMS symptoms, mood shifts, cramps, energy, and support cues without turning love into homework.
Cycles affect mood, energy, and relationship needs, but most partners are flying blind. You want to be supportive, you just don't always know what helps today. That's where Otty comes in.
Otty turns your partner's period calendar into simple daily advice, reminders, date-night ideas, and love-note nudges, so you always know how to show up. No lectures, no clinical charts, just warm, witty tips from a ridiculous little otter who wants you both to be happy.
WHAT YOU GET
Period & Cycle Tracking
Track your partner's cycle and see which phase they are in, from period days to PMS-sensitive days to higher-energy windows. Each phase includes simple guidance for mood, energy, cramps, and relationship support.
Daily PMS & Period Tips
Specific, phase-aware period tips delivered fresh every day. Not generic relationship advice. Real things you can do right now: "Deploy snacks immediately. Chocolate is not optional, it's tactical."
Date Ideas & Nudge Activities
Fun date ideas, snack missions, and couples conversation starters for every phase. Spin the slot machine and let Otty pick something unexpected.
Smart Notifications
One phase-aware daily reminder at 7 AM, plus partner messages when you pair. Extra cycle, period, PMS, and nudge reminders can be turned on in Settings.
Love Notes
Write a thoughtful love note once and schedule it to land later, right when your partner could use a little extra support.
Relationship Milestones
Never forget the dates that matter. Add anniversaries, first dates, and special moments. Otty counts down and celebrates with you.
HOW IT WORKS
1. Enter your partner's last period start date and cycle length
2. Otty maps the cycle phases and preps daily period tips
3. Use reminders, nudges, and love notes to show up like a legend
YOUR DATA IS SAFE
Your cycle data is stored locally by default. Sign-in is optional and used for cloud backup, partner pairing, profile photos, and cross-device sync. Subscription verification and shared partner features require network access. We never sell your data. Your period and cycle information stays private and secure.
Download Otty. Never drift apart.
The fact that this is built for both people and not just the girl is everything. My partner checks it on his own now, and he actually knows what my body is going through and what to do!!! Finally where has this been all my life
Developer Response
Thank you, this is the kind of review that stays with us. Otty was always meant for both people in a relationship, so knowing your partner now understands what you're going through and how to help means more than we can say.– Otty 🦦
Love this app
Davidb332
honestly downloaded this just to make my girlfriend happy lol but now i actually check it every morning. knowing what phase she's in changes everything. i used to think she was just randomly upset with me sometimes but now it all makes sense.
Developer Response
This kind of note means a lot to us. Coming in to make your girlfriend happy and ending up checking every morning yourself is honestly the whole goal. Thank you for writing it.– Otty 🦦
