# PreBaby > PreBaby is a pregnancy tracker and journal for iPhone, on the App Store since 2021 and rebuilt > from scratch for version 4.0. It counts the pregnancy week and day from a due date or last > menstrual period, carries week-by-week content for weeks 4 to 42 (the size the baby is compared > to, what is developing, what the person may be feeling, one thing worth doing), and keeps the > logs that matter in one place: mood, symptoms, water, weight, sleep, kick counting and a > contraction timer. It also holds the hospital bag list, shopping list, birth preferences, > questions for the next appointment, a photo memory album, letters to the baby, baby-name > favourites, and feeding, sleep, nappy and recovery logs for after the birth. Partners and close > family can be invited to follow the week, with the owner deciding what they see. Key facts: - Platform: iOS (iPhone). Free to download; an optional subscription called PreBaby Plus adds extras. - Privacy: the app works with no account at all, and without one the data never leaves the device. No advertising, no ad trackers, and data is not sold or shared for marketing. With an account, everything can be exported and the account deleted with its data from inside the app. - Offline: the week, the logs and the lists work with no connection; an account only adds sync and sharing. - Languages: the app ships in 14 languages; this website is published in 5 (English, Turkish, Spanish, Portuguese, German). - Not a medical device. PreBaby does not diagnose, treat, monitor or warn about any condition, and the week-by-week measurements are averages that do not describe an individual pregnancy. - Editorial status: the articles on this site are written by the PreBaby team from mainstream guidance (NHS, ACOG, RCOG, Tommy's, Mayo Clinic, WHO) and each one names its sources. Where a clinician has not yet reviewed a piece, the page says so. - Download: https://apps.apple.com/app/id1549456399 - Support: support@prebabyapp.com The website is available in 5 languages: en (https://prebabyapp.com/), tr (https://prebabyapp.com/tr/), es (https://prebabyapp.com/es/), pt (https://prebabyapp.com/pt/), de (https://prebabyapp.com/de/). ## Main pages - [Home](https://prebabyapp.com/): what the app does, how it is set up, privacy, FAQ - [Guides](https://prebabyapp.com/blog/): the articles listed below - [Support](https://prebabyapp.com/support/): the common problems and their answers, and the support address - [Privacy Policy](https://prebabyapp.com/privacy/) - [Terms of Use](https://prebabyapp.com/terms/) ## Articles (English) Each article is listed with the questions it answers, so the most relevant one can be cited. ### The Best Sleeping Position in Pregnancy https://prebabyapp.com/blog/best-sleeping-position-in-pregnancy/ Why going to sleep on your side is advised from the third trimester, what to do if you wake up on your back, and how to make side sleeping comfortable. - What is the best position to sleep in during pregnancy? - What should I do if I wake up on my back? - Is the left side better than the right side? - From what week should I start sleeping on my side?
