Your baby, week by week
What size your baby is, what's changing in your body, and what to do this week, all summarised from the NHS week-by-week guide, plus a short daily story.
A pregnancy diary for two
Bump Diary is a shared diary for you and your partner. Capture your bump every day, follow your baby's growth with NHS guidance, and get ready for the big day together.
From your first bump photo to your bump movie, and everything you'll share along the way.
Most pregnancy apps are made for one person. Bump Diary is one diary you share, each on your own phone.

From the first scan to the first weeks with your baby.
What size your baby is, what's changing in your body, and what to do this week, all summarised from the NHS week-by-week guide, plus a short daily story.
Ask about pregnancy from any screen and get an answer written from NHS pages, with links to read more. Warning signs always get your hospital's number first.
Choose where you're booked, and call its maternity triage line in one tap from the contraction timer, the movements card and anywhere else it matters.
Appointments with the NHS schedule, scan photos, a shared hospital bag checklist, a birth plan to share with your midwife, and a contraction timer on your Lock Screen.
Private daily check-ins with gentle insights, a movements log, blood pressure and weight with Apple Health, and reminders for folic acid and vitamin D.
Swipe through thousands of names, each with its meaning or popularity. Your votes stay private until you both like the same one.
Share the news, then keep the diary going: a shared log of feeds, nappies and sleep, and NHS guidance for the early weeks.
Log a kick or time a contraction from your Apple Watch, the Action button or Siri, and see your week on your Home Screen widgets.
If a pregnancy ends, you can pause the diary for both of you. Everything about the pregnancy stops, and you'll find NHS and charity support.
Swipe through a few of the screens.











Health information is summarised from NHS pages and links back to them. Hospital triage numbers are checked on each trust's own website.
No adverts, no tracking, and your data is never sold. Only the people in your diary see it. Health readings stay on your phone.
Export your whole diary at any time, or delete your account from inside the app. Read the privacy policy.
Bump Diary isn't a medical device and doesn't give medical advice. If you're worried about yourself or your baby, contact your midwife or maternity unit. If your baby is moving less than usual, call them straight away. In an emergency, call 999.
