Fertility Window Planner is the calm, private way to find your fertile window while trying to conceive. No ads, no data selling, no AI chatbot — just your own signs, read by a transparent engine that shows its work. LOG YOUR SIGNS IN SECONDS Record basal body temperature (°F or °C), cervical mucus, ovulation-test results, flow, intercourse and symptoms — one tap per day, editable any time. SEE YOUR FERTILE WINDOW The Dawn Arc and a phase-tinted calendar show the six days you're most likely to conceive, your predicted ovulation day, and your next period — each with an honest confidence tier. UNDERSTAND THE 'WHY' A BBT chart draws your temperature curve with the computed coverline, the shaded fertile window and your mucus/OPK markers — so you can see exactly how each prediction was made. Nothing leaves your device to compute it. BUILT FOR PRIVACY Your data is yours: protected by per-account security, never sold, no third-party trackers. Export or delete everything any time. PRO (optional subscription) Unlock full cycle history, cross-cycle chart overlay, personal pattern insights and saved summaries.
