Short answer

Bloom Journey works out your pregnancy week and day from your due date, last period, embryo transfer or insemination. Every day has its own note with sources, and you can see your baby’s size as a fruit, as a 3D model and at real size. It also includes a care path, a contraction timer, a movement log, a “Can I eat this?” food search and a memory journal. The app is free, with no account, ads or analytics. The optional Bloom Plus is a one-time purchase.

Getting started

How to get started

Setting up takes a couple of minutes, and you do not need to create an account.

Download the appBloom Journey is available for Android phones on Google Play, and the iPhone version is coming to the App Store. The app is in English, Finnish, Spanish, German and Russian.
Tell the app how to date your pregnancyChoose your due date, the first day of your last period and your cycle length, the date of an embryo transfer (day 3, 5 or 6 embryo) or the date of an insemination. If you do not know yet, you can start with a rough estimate. You can refine the dating later, for example after a scan, and nothing is lost.
Fill in the basicsChoose your country and emergency number and tell the app whether you are expecting one baby or twins. You can also choose the words that suit you, for example “baby” or “embryo, then fetus”.
Open the Today viewThe Today view shows your pregnancy week and day, today’s note, your baby’s size, the next step on your care path and the tools that are useful right now.
Make a backupYour data is only on your phone and is not saved to the cloud automatically. Make a password-protected backup file so you can restore your data, for example on a new phone.

Day by day

A note for every day

Bloom Journey follows your pregnancy calmly, one day at a time, and shows what the information is based on.

Pregnancy week and day

Your pregnancy is shown in weeks and days, for example 18+3, along with the trimester. After the birth, the app moves on to the so-called fourth trimester.

Daily notes with sources

The app has a short note for every day of pregnancy up to 42+0, 295 notes in all. The sources for each week’s content are shown in the app. The most cited sources are the UK’s NHS and publications from ACOG, WHO, NICE, RCOG and the CDC. Food information also draws on the Finnish Food Authority.

General information, not medical advice

The information in Bloom Journey is general and does not replace your midwife, nurse or doctor. The app is not a medical device and does not diagnose anything. If you are worried about your health or your baby, contact your maternity clinic or hospital. In an emergency, call the emergency number.

Baby’s size

Your baby’s size as a fruit, in 3D and at real size

It is easier to picture your baby’s growth when you can compare it with something familiar.

Fruit comparison

From week 4 to week 42, your baby’s size is compared with a fruit or vegetable. There are 34 comparisons.

3D model

This week’s fruit and baby can be viewed as a 3D model for free. The 3D models for other weeks are part of Bloom Plus.

Real size

Calibrate your screen with a bank card or a one-euro coin, and the app draws your baby on the screen at real size.

Where the measurements come from

The measurements are based on published growth charts: lengths from Robinson and Fleming (1975) for weeks 6–8 and from the INTERGROWTH-21st study for weeks 9–13, and WHO fetal growth charts (2017) from week 14. The earliest weeks are based on UNSW embryology data.

Care path

Care path: appointments, screenings and calendar

The care path brings your pregnancy appointments, tests and vaccinations together on one timeline.

The path has 36 items, such as the booking visit, dating scan, screening tests, anatomy scan, glucose test, vaccinations and appointments at around weeks 20, 26, 30, 34, 36, 38 and 40. Postnatal checks are included too.

You can mark each item as planned, booked, done or skipped, add your own items and write down questions for your next appointment. You can add appointments to your phone’s calendar as a calendar file and create a PDF pack for the birth.

The path is based on international guidance and does not follow any single country’s schedule. So compare it with the advice from your own maternity care. According to the app, country-specific guides are on the way.

Tools

Contraction timer, movements, food search and other tools

The order of the tools adapts to your pregnancy week: from week 36, the contraction timer comes first. You can also rearrange them yourself.

Contraction timer

The timer measures the length of contractions and the time between them, and counts contractions in the last hour and the averages. It includes a breathing ring, a labour mode that keeps the screen on, and your saved hospital number. The app does not tell you when to go: follow your hospital’s instructions.

Baby’s movements

Log movements freely or start a guided session of up to an hour. The app does not set a target number of movements.

“Can I eat this?”

Search 180 foods without an internet connection. For each one, the app tells you whether it is fine, should be heated until steaming hot, is best limited or avoided, or should be checked against local advice. Sources include the NHS and the Finnish Food Authority.

Symptoms and logs

Information on 60 symptoms and logs for blood pressure, blood sugar, weight and symptoms. A breathing exercise helps you relax.

Hospital bag and birth preferences

An editable hospital bag list (49 items in four sections) and birth preferences that you can export as an A4 PDF, in a second language too if needed.

Search

Search answers to 216 questions without an internet connection. The answers are written in advance, and the app does not generate them with AI.

Memories

Memories: journal, bump photos and letters to your baby

The Memories section keeps the story of your pregnancy, and it turns into a pregnancy book.

Journal

Write as much as you like. Today’s writing prompt is free, and the full prompt library is part of Bloom Plus.

Bump photos

The camera shows last week’s photo as a faint overlay and a level, so your photos line up from the same angle. You can turn the photos into a flip-book or compare them side by side. Saving the bump film as a video is part of Bloom Plus.

Letters to your baby

Writing letters is free. With Bloom Plus you can seal a letter to be opened after the birth, on the first or 18th birthday or on a date you choose. Opening a sealed letter is always free.

Pregnancy book

Your memories become a pregnancy book. A simple PDF is free. With Bloom Plus you get a print-ready PDF in A5 or a 21 × 21 cm square and can choose a theme for it.

Partner and widgets

Partner mode and widgets

Partner mode

Show your partner a QR code, and their phone works out the pregnancy weeks on its own, offline, and shows their own partner Today view. The code only contains the due date, the dating method, the region and the words you chose. Data is not synced between phones, so your journal and photos stay on your own phone. On Android, scanning the QR code uses Google’s ML Kit, which sends technical usage data to Google.

Widgets

On iPhone, the pregnancy week widget comes in small and medium sizes and for the lock screen. Android has two widgets: pregnancy week, and pregnancy week with baby’s size. If you have not told anyone yet, the widgets can stay neutral until 13+0.

Privacy

Privacy: no account, no ads, no analytics

Pregnancy data is sensitive. That is why Bloom Journey only stores it on your phone.

Encrypted databaseYour data is stored in an encrypted database whose key is kept in the phone’s secure keystore. Photos are protected by the phone’s own encryption.

FAQ

Frequently asked questions

Is Bloom Journey free?

Yes. The app’s core features are free, and there are no ads. The optional Bloom Plus is a one-time purchase that adds, for example, a print-ready pregnancy book, sealed letters and 3D models for every week.

Does a pregnancy app replace maternity care?

No. The information in Bloom Journey is general, and the app is not a medical device. Go to your maternity care appointments, and contact your clinic or hospital if you are worried.

Where is my data stored?

Only on your phone. Your data is stored in an encrypted database, and the app has no account or cloud service. That is why it is worth making a password-protected backup.

How is the pregnancy week calculated?

Bloom Journey works out your pregnancy week and day from your due date, the first day of your last period and your cycle length, the date of an embryo transfer or the date of an insemination. You can refine the dating later, for example after a scan.

Does the app work for IVF or twin pregnancies?

Yes. You can date your pregnancy from an embryo transfer (day 3, 5 or 6 embryo), and during setup you can choose twins or more. The care path then gets an extra-care item, and the journal gets prompts of its own.

Can my partner follow the same pregnancy?

Yes. Your partner scans a QR code, and their phone works out the pregnancy weeks on its own. The phones do not sync data with each other, so your journal and photos stay only on your phone.

How do I move my data to a new phone?

Make a password-protected backup file on your old phone and move it to your new phone. Then choose to restore from a backup during setup on the new phone.

Which languages is Bloom Journey available in?

The app is in English, Finnish, Spanish, German and Russian. It works on Android phones, and the iPhone version is coming soon.
