From the first flutter to the first cry — apps that track every milestone of your pregnancy.
Pregnancy has 40 incredible, terrifying, and wonder-filled weeks. The right app keeps you informed at every stage — what's developing this week, what symptoms are normal, when to call your midwife, and how to prepare for what's next. Here are the best pregnancy week-by-week apps in 2026.

The first trimester is when all the major organs and structures form. A good pregnancy app explains what's happening each week — from the fertilised egg implanting in week 3, to the heart beating in week 6, to the baby having all major organs by week 12. It should also tell you what symptoms are normal (nausea, fatigue, breast tenderness) and which ones warrant a call to your provider.
The second trimester is often the "golden period" — nausea typically eases, energy returns, and the bump becomes visible. Weekly updates should cover what the baby is developing, when you'll feel the first kicks (typically 16-24 weeks), and what to expect at each prenatal appointment.
The third trimester is when kick counting matters. From week 28, your doctor may recommend daily fetal movement monitoring. A good pregnancy app has a built-in kick counter that tracks sessions and alerts you if movement seems reduced. As you approach your due date, a contraction timer becomes essential for knowing when it's time to head to hospital.
WomensPal provides detailed weekly updates from conception through all 40 weeks of pregnancy. Each week covers what's developing (with baby size comparisons — this week your baby is the size of a mango), what symptoms are common and what's causing them, what to ask at your next appointment, and what to prepare for in the weeks ahead.
The kick counter starts from week 28 with a simple timer and session log — helping you track the count-to-10 method your doctor recommends. The contraction timer records the duration and interval of each contraction so you know exactly when to call your midwife or head to the hospital.
After birth, WomensPal transitions to postpartum mode — no need to switch apps or lose your pregnancy history. Your entire journey, from first period to fourth trimester, stays in one place.
Pregnancy+ has remarkable 3D and 4D models showing your baby's development at each stage. If seeing what your baby actually looks like each week matters to you, Pregnancy+ is the best visual experience available. The free tier includes weekly updates and a contraction timer; full features require a subscription ($9.99/month). It doesn't have a postpartum mode.
The third trimester is also when preparation becomes critical. The best pregnancy apps include:
