LadyOne is a gentle, private companion for your cycle, your pregnancy, and everything in between — built to stay entirely on your own device.
Your body, your data, your peace of mind.
CYCLE & FERTILITY
Track your period, understand your phases, and see what's ahead. Predictions learn your own rhythm — never a stranger's.
PREGNANCY, WEEK BY WEEK
Follow your baby's growth, log how you feel, and know what's normal — and, just as clearly, what's worth a call.
FAITH, IF YOU WANT IT
An optional worship companion that understands your cycle and its rulings — entirely yours to turn on, or leave off.
PRIVATE BY DESIGN
• Everything you log lives on your phone — not on our servers, because we don't have any.
• If you use more than one device, sync to your own private Google Drive carries it between them, end-to-end encrypted. We never see it.
• No ads, no trackers, nothing sold. There is no third party in the room.
• Erase everything, anytime — from the app, your Google Drive, and Health Connect, in a single choice.
SPEAKS YOUR LANGUAGE
Available in English, Arabic, Persian, Chinese, Hindi, Russian, Spanish, Portuguese, Indonesian and French — with full right-to-left support, so every language feels native.
No account required. Private by design.
