Menstrual Cycle Tracker vs PlainLife

Discover your body’s rhythm with a scientifically based fertility tracker designed to help you plan or avoid pregnancy naturally. Simply enter the first day of your last period, and the app predicts your next period, ovulation day, and the most fertile and least fertile days of your cycle. With Apple Health sync, your data stays automatically updated across all your Apple devices — so your fertility insights are always with you. * Scientifically Backed Methods * Our app includes two baby gender prediction methods: • Popular Method – a theoretical approach based on the well-known theory by Landrum Shettles, which suggests that the timing within the fertile window may influence the baby’s gender. • Scientific Method – a statistical, research-based approach developed by Rodrigo Guerrero, grounded in large-scale data from thousands of women. You can switch between them anytime in Settings. Please note: both methods provide probabilistic insights, not guaranteed results. * Full Version Features * Unlock deeper insights with the full version: • Daily pregnancy probability for any selected date. • Gender prediction probabilities for each fertile day. • Overall fertility chances during your current cycle. • Automatic Apple Health sync between devices. * How It Works * To create your personal fertility calendar, simply provide: • The first day of your last period. • Your average cycle length. • Your luteal phase length (default works for most users). Ideal for women with regular cycles — but also reliable for estimating ovulation using your average cycle length. * Empower Your Reproductive Journey * Whether you’re trying to conceive or prefer natural birth control, this app provides clarity, accuracy, and peace of mind — backed by science and made even smarter with Apple Health integration.

PlainLife is the whole human health loop — womb to next womb — in one private, offline app. Most health apps cover a single slice: a pregnancy app here, a parenting app there, a period tracker somewhere else. PlainLife brings the entire arc together as one continuous, intergenerational loop, because each stage shapes the next. SIX CHAPTERS, ONE LOOP • Origins — preconception health for both partners • Birth — pregnancy week by week, warning signs, labor prep, postpartum • Childhood — milestones, illness triage, feeding, sleep, growth • Adolescence — puberty, cycle, and reproductive & sexual health • Fertility — conception and planning the next generation • Generations — how each stage echoes forward WHAT YOU GET • Ask PlainLife — ask anything and get answers from a bundled, cited knowledge base, fully offline. • Plain-language guidance with tappable sources and clear "when to seek care" triage. • Tools — kick counter, contraction timer, tracking, reminders, glossary, and full-text search. • Doctor summary — turn what you've tracked into a clean handoff for your clinician. • Voice input and read-aloud. PRIVATE BY DESIGN PlainLife is 100% on-device. Your information is stored encrypted on your phone — no account, no servers, no tracking — and it works fully offline. Export or delete everything at any time. PLAINLIFE PLUS (optional, one-time) The core is free for everyone, including every safety & emergency guide.
