Otty is a period and menstrual cycle tracker that works whether the cycle is yours or your partner's. Pair up, and you can both see what's coming and how to prepare. Tell Otty when the last period was, and Otty fills in the rest: when the next period is due, the likely ovulation day, and which week of the cycle each day falls in. Every day brings one tip for that point in the cycle and the reason it works. Some days that is what to eat. Some days that is how to sleep better. If you track your own cycle, you get the full toolkit: the phase calendar, quick daily check-ins, symptom patterns, and your own Comfort Menu. If you track your partner's cycle, you get one tip a day on how to help. Pair up, and everything connects: check-ins, comfort preferences, love notes, and nudges reach the right person on the right day. WHAT YOU GET Period & Cycle Tracking Every day on your calendar is painted with its phase, from period days to PMS days to the higher-energy window. You also see the expected next period, the likely ovulation day, and your milestones, and you can tap any day for a plain-language guide to it. Daily Tips One tip a day for the phase you are in, with the reason behind it, whether the cycle is yours or your partner's. Real things to do today: "Restocking her period supplies now beats a 10pm pharmacy run in three weeks." Daily Check-Ins & Your Patterns Note how the day went and any symptoms in seconds. Otty answers with what is behind it and what helps, and after about two cycles shows which symptoms keep turning up in which phase. Comfort Menu Write what actually helps you in each phase, in your own words, from the exact snack to the things to skip. Your partner sees the list when that phase begins. Every item can be shared or private, you can hide the whole menu whenever you want, and a tap of the heart shows what is handled. On your own, it is your personal comfort kit. Comfort Coupons Promise your partner a small thing ahead of time, from a blanket-burrito evening to a fully planned date. Ninety coupons to choose from. They keep them in a wallet and cash one in when they need it, and you get the heads-up to deliver. Deck Night 300 conversation cards across six decks, played together on one phone. Whoever holds the phone reads the card out loud and answers first. Otty points out the deck that fits the phase. Let's Roll Turn the gumball machine for tonight's plan, with a lineup that matches the phase: cozy on period days, romantic in the higher-energy window. Love Notes Write your partner a short note and send it now, or schedule it for a day they could use it. Milestones Add first dates, anniversaries, and the moments that matter. Otty counts the days and, if you want, reminds you a week before and on the day. Notifications One tip a day, a heads-up before the period and before each phase change, and partner notes when you pair. Every type can be switched off in Settings. HOW IT WORKS 1. Tell Otty when the last period was, yours or your partner's. 2. Otty maps the phases and gives you one tip a day. 3. Pair up when you want to, and the shared parts switch on. YOUR DATA IS SAFE Your cycle data is stored on your phone by default. Sign-in is optional and used for backup, partner pairing, profile photos, and sync across devices. Partner sharing is opt-in and item by item: you decide exactly what your partner sees, you can change it anytime, and no one is notified. Subscription verification and shared partner features need a network connection. We never sell your data. Otty speaks English, Español, Français, Deutsch and Português. Never drift apart. ## Key features - Couples period and cycle tracking - Daily PMS and period tips - Date ideas and activities - Smart notifications and reminders - Scheduled love notes - Relationship milestone tracking ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | Otty Premium | $7.99 | per month | | Otty Premium | $5.99 | per month | | Otty Premium | $47.99 | per year | | Otty Premium (Annual) | $39.99 | per year | | Premium Monthly | $1.99 | per month | | Premium Annual | $15.49 | per year | ## Is Otty Period Tracker & Calendar safe?

It feels like so much more than just a period tracker! **Developer response:** So glad the tracking plus the practical tips for each phase are working for you. Thank you so much. – Otty 🦦 ### 5/5 — Learned a lot! *2026-10-09* I got Otty to understand my wife's cycle and honestly I've learned way more than I thought i would. **Developer response:** Glad it’s teaching you more than you expected. Thank you for sharing this. – Otty 🦦 ### 5/5 — Incredibly Helpful *2026-08-31* She’s not even on the app, I just track it myself. I know where she’s at each week and what that means for her without having to ask. **Developer response:** It means a lot to hear this. Knowing what each week means for her, on your own and without needing to ask, is exactly the kind of quiet support that makes a difference. Thank you. – Otty 🦦 ### 5/5 — Best period tracker app *2026-08-23* So happy I found Otty, the other apps I’ve had are not as informative and getting the notifications everyday helps me understand where I’m at with my cycle. Worth the subscription!’n **Developer response:** Happy you found us too! Glad the daily notifications are keeping you clear on where you are in your cycle, and hearing it feels worth the subscription means a lot. – Otty 🦦 ### 5/5 — Best app *2026-08-23* He finally gets it!!! I got my husband on Otty so he could understand what I go through each month. He understands my symptoms now and knows how to be there for me when I need it! **Developer response:** He gets it now, and honestly, we are cheering over here. Way to get him on board. – Otty 🦦 ### 5/5 — Works with an irregular cycle *2026-08-21* Mine has never been regular so I wasn’t expecting much. Otty adjusts based on what I actually log instead of assuming I’m textbook, and the dates have lined up with my real life. **Developer response:** Thank you for giving Otty a shot even when you weren't expecting much. Really glad the dates are lining up with your real life. – Otty 🦦 ### 5/5 — Built for me too *2026-08-20* A lot of these apps treat the partner like an add on. I get a full view of my wife's cycle and what's coming up, laid out in a way that's easy to understand. **Developer response:** So glad Otty gives you the full picture, laid out clearly. Thank you. – Otty 🦦 ### 5/5 — Same page as her *2026-08-14* Cool because we’re both on the app looking at the same thing. She doesn't have to fill me in on where she's at. **Developer response:** Love that you're both in it together, and that she doesn't have to catch you up. – Otty 🦦 ### 5/5 — Tracking the things that Matter!!!!! *2026-08-11* I don’t have a partner to share this with just yet, but after using Otty, I already love it! It’s a great way to check in with my cycle and someday, a great way to see just how thoughtful and willing my future partner is to understand it too. Love this app! **Developer response:** So glad Otty is a good way to check in with your own cycle. Whenever the day comes to share it, everything will be ready. Thank you for this lovely review. – Otty 🦦 ### 5/5 — Doesn’t feel clinical *2026-08-06, version 1.0.19* It’s warm and simple. I don't feel like I'm filling out a medical form every time I log something. ## Frequently asked questions about Otty Period Tracker & Calendar ### How does Otty help partners understand cycles?
