About

Sex is part of life. It affects mood, relationships, confidence, stress, sleep, and how connected you feel — but most of us do not track it with the same care we give workouts, food, or sleep. Kairos makes intimacy tracking feel normal, private, and a little more human. Use Kairos to log desire, mood, solo time, partnered intimacy, symptoms, energy, notes, and context. Over time, those small check-ins become patterns you can actually use: what boosts desire, what gets in the way, when connection feels easier, and what your body may be trying to tell you. WHAT YOU CAN TRACK • Libido and desire over time • Solo and partnered experiences • Mood before and after intimacy • Energy, sleep, workouts, symptoms, protection, duration, and notes • Relationship connection and timing • Custom fields that fit your real life WHY IT HELPS • Notice patterns without guessing • Talk with a partner with less pressure • Understand your rhythm instead of judging it • Keep a private record of your sexual wellness • Bring better context to care conversations if you choose PRIVATE BY DESIGN • Your data is stored locally on your device • iCloud sync uses your private iCloud database • No third-party analytics • No ad tracking • No social feed • No selling intimate data • Permissions are requested only when needed Kairos is built for adults who want to be honest about intimacy without making it weird. Track what matters, skip what does not, and keep your private life private.
