Otty now counts down to the next period, the next ovulation day and the next phase on Today, each with a date, whether the cycle is yours or your partner's.
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.
Obsessed with this app even as a single girl just tracking my period. It makes everything I ever guessed about my cycles way more clear and predictable. It’s been spot on. Not to mention it’s just so cute and makes me happy every time I open it. I used to use Flo to track but Otty is way better.
Developer Response
So glad Otty is making your cycles feel clearer and more predictable, and that the predictions have been spot on. Finding something you're actually happy to open means a lot. Thank you.– Otty 🦦
Tracking the things that Matter!!!!!

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 🦦
Best app
Oriany
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 🦦
The next period, the next ovulation day and the next phase now sit under the phase bar on Today, each with a count and a date. It works whether the cycle is yours or your partner's.
• Today's Cycle Phase card shows three lines: Next period, Next ovulation, and the day the next phase begins, like "Chill begins · 5 days · Oct 3". While a period is on, the first line counts down to its last day.
• The next-phase count in onboarding, on the paywall and on Today now lands on the day that phase starts, the same day the calendar shows.
• Zen carries a moon everywhere now, and the phase and ovulation icons match across Today, the calendar and the Phase Guide.
