Otty is a period and cycle tracker built for couples that works just as well solo. It maps the month into simple phases with plain names like Storm (Period) on one shared calendar, and each day it offers one specific suggestion for what helps with mood, energy, and support right now. Couples who pair get Comfort Coupons, Deck Night conversation cards, a shared Comfort Menu, love notes, and nudges that reach the right person at the right time. Cycle data is stored locally by default and sign-in is optional. Available in English, Spanish, and French on iOS, free to try with a subscription for the full feature set.
Features
Shared phase calendar with plain-language phase names. One specific phase-aware tip every day, whether the cycle is yours or your partner's. Daily mood and symptom check-ins that reveal your patterns by phase. Comfort Coupons, Deck Night conversation cards, and a shared Comfort Menu for couples. Love notes, date ideas, and relationship milestones. Local-first data with optional sign-in.
Use Cases
Tracking your own cycle with quick daily check-ins, knowing how to support a partner during each phase, and keeping a couple connected through PMS week without guesswork.

Hi Fazier! I built Otty because every period app I could find was built for one person, while the other person in the relationship was left guessing. Otty puts the cycle on one shared calendar with plain phase names like Storm (Period), and each day it hands the partner one specific thing to do, more "heavy blanket and zero plans tonight" than "be supportive." It works solo too, with check-ins and symptom patterns by phase. It is live on iOS in English, Spanish, and French, and I would love feedback, especially from anyone else building consumer apps for couples.
