Momi pregnancy tracker features

Last updated 20 October 2026 · Screenshots from the shipped app

Week-by-week pregnancy updates with baby size and development milestones

Momi's home screen shows your current week and day, how many weeks are left, and how big your baby is this week, with a fruit or vegetable comparison and an approximate length and weight. A short weekly guide explains what's developing and what you might notice. Read the same information on the web in pregnancy week by week.

Due date calculator (estimate from last period or conception date)

Enter the first day of your last period, or a known conception date, and Momi estimates your due date using the standard 280-day count. If your midwife or doctor gives you a different date after your dating scan, use theirs. Want to check first? Try the free due date calculator.

Trimester guidance and reminders

Momi shows which trimester you're in and gives daily and weekly tips that fit your stage, from early nausea to packing your hospital bag. For an overview of each stage, see pregnancy trimesters.

Weight & health tracker

Log your weight as often as you like and see how it changes over the weeks. Your provider will tell you what gain is right for you; our guide to pregnancy weight gain week by week explains the usual ranges.

Notes / pregnancy journal and dad diary

Write how you're feeling in the Mom's diary, while your partner adds their own entries in the Dad's diary on the same phone. Add a bump photo each week and keep ultrasound pictures with your notes. See pregnancy journal examples.

Visits and medicine reminders

Keep your upcoming prenatal and midwife appointments in one list, and set reminders for vitamins or medicines. Not sure what to expect? See the pregnancy appointment schedule.

Kick counter and contraction timer

Kick counter: tap once for each movement. Momi times the session and saves it, so you can see how long it took to feel 10 movements. If your baby's movements slow down or change, contact your maternity unit straight away; don't wait for a count.

Contraction timer: tap at the start and end of each contraction. Momi logs how long each one lasts and how far apart they are. Your midwife or hospital will tell you when to call.

Both are also free on the web: kick counter and contraction timer.

Pregnancy timeline and PDF ebook export (Premium)

Premium turns your diary entries, bump photos and milestones into a timeline of your journey, which you can export as a PDF ebook to keep or print. Premium also removes ads.

Baby-health articles and daily / weekly tips

Short articles and tips explain common symptoms, tests and baby care in plain language. They're general information; your midwife or doctor knows your situation best.

What Momi does not do

We'd rather you know up front:

• No period or ovulation tracking. Momi is for pregnancy only.
• No community forum.
• No 3D baby models.
• No partner sync across phones yet. The Dad's diary lives on the same phone.
• Not a medical device. Momi doesn't diagnose anything or replace your maternity care.
• Ads in the free version. The App Store privacy label lists data used to track you for third-party advertising. See our privacy policy.
• English only in the store listing for now.
