Frequently asked questions
Do these apps replace medical care?
Not at all, and none of them claims to. They help you understand what happens each week and keep an orderly record of weight, symptoms and appointments that is useful at your check-ups. Your pregnancy is monitored by your midwife and your obstetrician, and any symptom that worries you should be discussed with them, not with an app or a forum.
What is the contraction timer for?
To record how long each contraction lasts and the interval between them, which is exactly what you will be asked when you call the hospital. Pregnancy+ and the others include it, and you just tap when a contraction starts and when it ends. Your midwife will tell you when to go in, based on your specific case.
Which is the best free pregnancy app?
Embarazo Semana a Semana offers the most without paying and is the highest rated, although it shows ads. BabyCenter is also free for the essentials and adds the community. Pregnancy+ and Wachanga keep part of their content behind a subscription.
Is the advice in the community forums reliable?
As emotional support and for sharing experiences they are genuinely valuable, especially because you are talking to people at exactly the same week. As a source of medical judgement, no: what worked for someone else does not apply to anyone else's case, and forums carry a fair amount of misinformation. BabyCenter has its editorial content reviewed by professionals, but that does not cover the messages posted by users.
