Koko is a period tracker that feels kind rather than clinical. Log your cycle, see what is coming, and get something that actually helps on the days it hurts. WHERE YOU ARE, EVERY DAY Open the app and see your cycle day, the phase you are in, and what that usually means for energy and symptoms. No hunting through menus. A CALENDAR THAT MAKES SENSE Period days, your estimated fertile window and predicted ovulation, all on one month view. Tap any day to see or change what you logged. RELIEF FOR EXACTLY WHAT YOU FEEL Cramps, lower back, nausea, low energy. Each one has its own short session of guided movement, breathing and warmth. Movement sessions can use your camera to show you when you are actually in the shape, so you are not guessing from a diagram. FOOD IDEAS WITH THE EVIDENCE ATTACHED Suggestions carry a label showing how strong the research behind them really is. Nothing is dressed up as more certain than it is. LOG MORE THAN THE BASICS Flow, pain, mood, energy, symptoms, discharge, temperature, ovulation tests, products, supplements and food. Add your own symptoms if ours do not fit. It all feeds into your trends over time. SOMETHING TO TAKE TO YOUR DOCTOR Months of logs become a clear summary: cycle lengths, where the pain is, how it feels, and how often it got in the way of normal life. Useful when you struggle to explain it all on the spot. SHARE ONLY WHAT YOU CHOOSE Invite a partner, friend or family member and pick, for each person, exactly what they can see. Your phase, your predicted dates, your symptoms, or nothing at all. Change it or remove them whenever you like. Nothing is shared unless you switch it on. GENTLE REMINDERS A nudge when your period is expected, when your fertile window opens, or just to log the day. YOUR PRIVACY Camera sessions run entirely on your device. Nothing from them is recorded, saved or sent anywhere. Koko gives you estimates based on what you log. It is not medical advice, not a diagnosis, and not a reliable form of birth control.
