About Otty: Period & Cycle Tracker
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.

Otty now confirms ovulation from Apple Health.

• Once a cycle's ovulation is confirmed, your next period estimate counts from that day.
• When a period runs past its estimated date, Otty says it's expected any day instead of assuming it started.
• In Cycle history you can now remove every logged period and start fresh.
• Plus improvements to Today and the calendar, and speed and stability fixes.
1.0.40
Otty now works on iPhone Duo. Closed, open upright, or open on its side, every screen fits the display you're holding. Plus improvements to the daily check-in and the calendar, and speed and stability fixes.
