I refer to Ovia daily and I love having it during my first pregnancy. I really love the updated videos you receive when you start a new week in pregnancy. I also love that you get recipes, tips, daily baby updates, and even baby milestones (such as lung surfactant developing to that the baby can survive childbirth if born early). I highly recommend this app. Its the best by far.
