Pregnancy Week Calculator tells you exactly how far along you are and walks you through your pregnancy one week at a time — calmly, privately and completely offline.
Unlike most pregnancy apps, you can calculate your dates the way that fits YOU. Choose from six methods and the app does the rest:
- Last period (LMP)
- Conception or ovulation date
- IVF transfer (day-3 or day-5)
- Ultrasound (weeks + days measured at a scan)
- A due date you were already given
From there you'll see your current week and day, your trimester, your estimated due date and a friendly countdown — plus how far along the whole journey you are.
WHAT'S INSIDE
- 40-week journey: every week explains what's happening with your baby and gentle tips for you.
- Baby size comparisons: see your little one measured against a familiar fruit or object, with approximate length and weight.
- Week detail: swipe through any week from 1 to 40 to look ahead or back.
- Kick counter: an easy tool to count baby's movements and time each session.
- A home-screen widget with your current week and countdown.
- Beautiful light and dark themes.
PRIVATE BY DESIGN
Your pregnancy is personal. Everything stays on your device — no account, no sign-up, no cloud. Your dates never leave your phone, and the app works fully offline.
