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. 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 and Français. Never drift apart.

  • This app has not received enough ratings or reviews to display an overview.

Otty's phase guides now say what is happening and one thing to do. • Every partner-view phase description is rewritten: what her body is doing this week, then one concrete thing you can do tonight, like the iron-rich dinner or the heating pad already warm. • Onboarding, the daily tip, and a few Settings lines read plainer, in English, Español and Français. • The date field in Milestones stays inside its card.
