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.
