Fertility Window Planner vs SleepBlend AI

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.

SleepBlend is a sound console for bedtime. Instead of scrolling a wall of tracks at midnight, you compose tonight's blend from a handful of voices — rain, ocean, wind, coloured noise, a warm drone — each generated on your device in real time, with its own volume and its own place in the stereo field. Nothing to download, and no loop that comes round again at 3am. COMPOSE YOUR OWN SOUNDSCAPE Stack voices in the multi-layer mixer and hear the blend change as you move each slider. The Resonance Ring shows the mix as bands of light around a still centre — when the voices sit in balance it settles into an even halo. A SLEEP TIMER THAT FADES, NEVER STOPS DEAD Set a timer with quick presets and a gentle fade-out over the last few minutes, so the night ends softly instead of cutting to silence. A blend keeps playing with the screen locked. ONE HONEST NUMBER Give a one-minute check-in in the morning — how quickly you drifted off, how rested you feel — and the Sleep Mix Score reflects how each blend works for you. It is built only from your own check-ins, shown with a transparent five-part breakdown, and it stays quiet until there is enough of your own data to be honest. Nothing is measured: no sensors, no wearables, no microphone. IT LEARNS WHICH VOICES SUIT YOU Over time the app surfaces which sounds turn up on the nights you settled faster, labelled as a pattern in your own logs — an association, not a cause. Tonight's recommendation is ranked from the same data. Every one of these calculations runs on your device, from your own entries. FREE, AND GENUINELY USEFUL The whole play loop is free: the full mixer with per-voice volume and stereo balance, the core voices, the sleep timer and gentle fade, the morning check-in, your Nights Composed streak, a nightly wind-down reminder and a 7-night rest trend. Free keeps up to three saved blends — and a blend you have saved is always free to replay, edit, favourite and delete.
