About Otty
Otty is a period and menstrual cycle tracker that works whether the cycle is yours or your partner's. 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, 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.
Each day Otty gives you one plain fact about the body and one thing to do about it, and a small otter holds your hand through the month.
How Otty started
Otty started with a phone call. The founder was catching up with his girlfriend when he noticed her energy was a little different that day. She mentioned her period was starting, and they ended up talking honestly about what those weeks actually feel like, and how much of that he had never seen from the outside. One thought stuck with him afterward:
That question became the whole product. Most partners want to show up. They want to comfort, to understand, to get it right. What they are missing is rarely care; it is context. So Otty puts the context on their phone: the phase their person is in today and one specific thing that would actually help.
Why a sea otter
Sea otters hold hands while they sleep so the current doesn't pull them apart. Relationships drift for ordinary reasons: hormone shifts, stress, busy weeks, small misunderstandings that stack up. Otty is the hand-hold, a small daily reason to reach toward each other. It is also why our tagline is three words long: Never drift apart.
What we believe
Every feature and every word starts with how someone feels. If it doesn't feel warm, it doesn't go in.
Cycle education matters, and it still doesn't have to feel like homework. If we can teach it with a pizza emoji, we will.
No one should feel shame for not knowing something they were never taught. Otty meets you where you are and celebrates that you showed up.
A text that says "thinking of you" counts. We don't wait for grand gestures to start cheering.
How we build it
A few product decisions follow from those beliefs, and we hold them even when they cost us the flashier feature.
Consent comes first. Sharing your cycle in Otty is invite-only: you decide whether to pair, you decide what your partner sees, and you can turn sharing off anytime in Settings. Our cycle sharing page walks through exactly what a partner sees and what they never see.
Nothing is graded. Otty offers ideas and never assigns homework. Missing a day changes nothing, and we are glad when you are back.
Your data stays yours. Cycle data is stored locally on your device by default, signing in is optional and exists for backup and pairing, and we never sell your data. We put it on every page of this site because we mean it: Otty is a relationship company, not a data company.
Who makes Otty
Otty is built by a tiny team, with a bit of help from AI tools. The final call on everything, from Otty itself to the blog, is ours, and we read every review and every support email. Our health content follows a written editorial policy, and when we get something wrong we want to hear about it. You can reach a human at ottyteam@gmail.com or through the support page.
