What's New in Otty Period Tracker & Calendar

1.0.41

October 25, 2026

Otty now confirms ovulation from Apple Health. • Connect Apple Health, and Otty reads the ovulation tests, basal body temperature and cervical mucus you log there to confirm the day you ovulated. Read-only, as always. • 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.

User reviews

Actually helpful tips!

Beyond tracking my period, I love that it gives me practical tips on what to do and what to eat during each phase of my cycle. It feels like so much more than just a period tracker!

Response from developer

So glad the tracking plus the practical tips for each phase are working for you. Thank you so much. – Otty 🦦

Learned a lot!

I got Otty to understand my wife's cycle and honestly I've learned way more than I thought i would.

Response from developer

Glad it’s teaching you more than you expected. Thank you for sharing this. – Otty 🦦

Incredibly Helpful

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.

Response from developer

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 🦦

Best period tracker app

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

Response from developer

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 🦦

Best app

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!

Response from developer

He gets it now, and honestly, we are cheering over here. Way to get him on board. – Otty 🦦
