Stop guessing how she feels. Luteal phase? Estrogen surge? Follicular window? You don't need to know any of that. Built for partners who want to better understand, support and connect — without awkward conversations, confusing medical terms or guesswork. 10-second setup. That's it. Start understanding what is happening now, what is coming next, and when she may need more patience, space or support. You don't even need to open the app. Everything is available directly from the Home Screen widget. Try free for 14 days. WHAT YOU GET • Daily mood, energy and fertility indicators • Widget for instant updates • Get notified when phases change • Smarter predictions over time • View upcoming phases in advance • Set personal notes and reminders • Fully private, offline and biometric-protected BUILT FOR PRIVACY Everything stays on your device. No account. No uploads. No cloud. No servers. Delete or reset the app and every record disappears with it. Not a surveillance tool. A thoughtfulness tool. HOW IT WORKS Know Her uses logged cycle data to estimate upcoming phases and important transitions. Predictions become more accurate over time as more cycles are added.
