I have played around with so many different apps for documenting or following up on the haps of my baby and my body. I wasted so much time! Apart from the sticker journal, that is obviously the best way to document your pregnancy, but as far as an app goes, I would definitely recommend the Pregnancy + app.
The app shows you 3D models of your baby week by week. You can see how big your baby is and exactly how it looks.
The app also has daily support articles on all of the things you experience during pregnancy. A lot of my questions have been answered this way. It’s fantastic.
Another cool feature is that you can record your details from the doctor whenever you visit (weight, height, blood results etc.), you can keep your health data in one place.
You can also record baby kicks and contractions with this app! It’s really one that has everything and when your baby has been born, there is a sister app bonus called Baby+ that helps just as much with your daily life with a baby!
