What's New in MoonFlow

1.4.5

October 1, 2026

A gentler look back, and estimates that are honest about uncertainty. • Your week, gently reflected — a new weekly card on the You tab shows what you logged, with no scores and no pressure. You can hide it anytime in Settings. • Your next period now appears as a likely window instead of a single day, so arriving a little early or late feels expected, not alarming. • Your fertile window is explained around your own goal — whether you are simply tracking, hoping to conceive, or just want fewer surprises. • Tap any calendar day to see what you logged kept clearly separate from what is estimated. • Daily Log now keeps the symptoms you use most within easy reach. • Ask MoonFlow understands much more about cycles, symptoms, pregnancy and intimate health, and now replies in your own language. (Premium; uses Apple Intelligence on supported iPhones.) Fixes and refinements • Fixed a crash when opening the Calendar • Fixed Daily Log sometimes showing another day's entry • Fixed a duplicate point in the cycle chart and a repeated countdown on the home screen • The Continue button now stays visible on every onboarding step MoonFlow now requires iOS 15 or later. As always, your data stays on your device. Thank you for being here.
