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 iPhone — not on our servers, because we don't have any. • If you use more than one device, Apple's private iCloud sync carries it between them. 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 iCloud, and Apple Health, 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. LADYONE PLUS LadyOne is free to use. LadyOne Plus unlocks deeper insight into everything you track, as a monthly or yearly subscription. Payment is charged to your Apple ID at confirmation of purchase. Your subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings. Privacy Policy: https://ladyone.app/privacy Terms of Use: https://ladyone.app/terms

Verdict
The clearest difference is update cadence: Comfi at every 5 days against LadyOne's every 10 days. Comfi also leads on iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
