New: Deck Night. Six decks of conversation cards for the two of you, a quick round or a full session, and Otty suggests the deck that fits the phase.
Be the partner they brag about.
Otty is a period tracker and cycle tracker built for couples that works just as well solo. At its core it's a complete period tracker: map your phases, log how you feel, and understand your own cycle, no partner required. And when there is someone who loves you, Otty helps them show up right.
If you track your own cycle, you get the full toolkit on your own: phase mapping, quick daily check-ins, symptom patterns, and a personal comfort kit. If you track your partner's, you get specific phase-aware tips so you stop guessing what helps. If you pair up, everything connects: check-ins, comfort preferences, love notes, and nudges reach the right person at the right time.
No lectures, no clinical charts, no daily chores. Just warm, witty help from a ridiculous little otter who wants you both to be happy.
WHAT YOU GET
Comfort Menu (NEW)
Say what actually helps once, phase by phase, from the exact snack to the things to skip. Your partner sees the right list at the right time, in your words instead of guesses. Every item can be shared or private, you can hide the whole menu whenever you want, and a tap of the heart shows what's handled. No partner? It doubles as your personal comfort kit.
Daily Check-Ins & Your Patterns
Log mood and symptoms in seconds. Otty responds to every check-in, adapts today's playbook to what you logged, and after two cycles reveals your real patterns: how your mood moves by phase and which symptoms repeat.
Period & Cycle Tracking
See which phase it is, from period days to PMS-sensitive days to higher-energy windows. The calendar marks estimated ovulation, the expected period start, and your milestone dates, with a guide in plain language.
Daily PMS & Period Tips
Specific, phase-aware period tips delivered fresh every day, whether the cycle is yours or your partner's. Not generic relationship advice. Real things you can do right now: "Deploy snacks immediately. Chocolate is not optional, it's tactical."
Date Ideas & Nudge Activities
Fun date ideas, snack missions, and couples conversation starters for every phase. Spin the slot machine and let Otty pick something unexpected.
Smart Notifications
One phase-aware daily reminder at 7 AM, plus partner messages when you pair, including a gentle heads-up when your partner logs a rough day. Extra cycle, period, PMS, and nudge reminders can be turned on in Settings.
Love Notes
Write a thoughtful love note once and schedule it to land later, right when your partner could use a little extra support.
Relationship Milestones
Never forget the dates that matter. Add anniversaries, first dates, and special moments. Otty counts down and celebrates with you.
HOW IT WORKS
1. Enter the last period start date and cycle length, yours or your partner's
2. Otty maps the cycle phases, preps daily tips, and learns from your check-ins
3. Solo or paired, use the Comfort Menu, reminders, nudges, and love notes to show up like a legend
YOUR DATA IS SAFE
Your cycle data is stored locally by default. Sign-in is optional and used for cloud backup, partner pairing, profile photos, and cross-device sync. Partner sharing is always opt-in and item-by-item: you decide exactly what your partner sees, and you can change it anytime, with no notifications sent. Subscription verification and shared partner features require network access. We never sell your data. Your period and cycle information stays private and secure.
Download Otty. Never drift apart.
Deck Night is here: 300 conversation cards made for the two of you.
• Six decks with their own personalities, from Warm-Up's silly icebreakers to How Well Do You Know Me's guess-then-reveal rounds to Desire's slow-burn questions.
• Pick a quick 5-card round or a full session, swipe through together, and skip any card to get a fresh one in its place.
• Hit Shuffle to mix all six decks, and Otty points out the deck that fits the phase, like Comfort & Care during Storm (Period).
• The Activities tab is now a proper hub: Deck Night, the returning Let's Roll slot machines, and your Comfort Menu, each one tap away.
• Let's Roll now shows a lineup matched to the phase, so Storm (Period) days lean cozy and Glow (Ovulation) days lean romantic.
• Your patterns moved to the Calendar tab, right next to the cycle data they read.
Small fixes and polish throughout.
