Fertility & Pregnancy Companion
The journey of becoming a parent
deserves something more personal.
From your first cycle log to ovulation predictions to the day you hold your baby — deeply private, entirely on your device. No accounts. No data leaves your hands.
Be the first to know when Jaan launches.
Seven thoughtful spaces that grow with you — from understanding your cycle to the day you hold them.
Log your period, track cycle length, and understand your body's rhythm. Intelligent predictions learn from your unique patterns over time.
Pinpoint your fertile window with precision. Track basal temp, cervical mucus, and LH surges in one beautiful timeline.
Your daily snapshot. Track vitals, read your affirmation, and feel grounded — all in one glance.
Week-by-week growth, size comparisons, milestones — a window into the world forming inside you.
Mood, memories, the first kick, the quiet fears — held safely, just for you.
Track water, sleep, symptoms, and mood. Gentle nudges to care for yourself.
Birth plan builder, hospital bag checklist, appointment tracker, and contraction timer. Prepare with clarity, not overwhelm.
Jaan doesn't start at pregnancy. It starts wherever you are — tracking your cycle, understanding your fertility, and seamlessly transitioning when the time comes.

Jaan has no servers, no cloud, and no third parties. Everything lives on your device and nowhere else — because it was never ours to begin with.
Jaan /jɑːn/
From Persian (Farsi) — جان
In Persian, jaan means life itself — and it's what you call the people you love most. Your child, your partner, the center of your world. It's whispered to a newborn, breathed in lullabies, said a thousand times and never enough.
We named this app Jaan because that's what this journey is really about — life, in every sense of the word.
We're putting the finishing touches on something we're proud of. Leave your email and we'll let you know the moment it's ready.
No spam. Just one email when we launch.
