Your baby size tracker is the simplest, most beautiful way to follow your little one's growth from the very first week of pregnancy all the way to delivery day. Whether you are newly expecting or deep into your third trimester, baby size tracker keeps you connected to your baby's journey with clarity, warmth, and the information that actually matters. Every week is a new milestone, and baby size tracker gives you everything you need to know exactly what size is my baby right now. From a tiny poppy seed at week 4 to a full watermelon at week 40, you will always know the weekly baby size with fun, relatable fruit comparisons that make the numbers feel real. Each comparison comes with your baby's actual length and weight so you always have a complete picture. Know Your Baby's Size Every Week Baby size tracker covers every week from 4 to 42 with precise length and weight data, your baby's measurements in centimeters or inches, and a warm description of what is developing this week. The moment you open the app, you see the size of baby right now — no searching, no guessing, just a clear snapshot that updates automatically as your due date approaches. A celebration popup greets you each time a new week begins. Log Your Fundal Height Measuring fundal height at prenatal appointments is one of the clearest ways to confirm the size of baby is on track. Baby size tracker lets you log each measurement in centimeters or inches and instantly compares it to the clinical reference for your current week. A color-coded badge tells you whether your reading is on track, above, or below the expected range — giving you useful context before your next appointment. Record Your Ultrasound Scan Data After every ultrasound, your baby size tracker becomes your personal record keeper. Log the estimated fetal weight alongside head circumference, abdominal circumference, and femur length. Every entry is saved and grouped by week so your full measurement history is always a tap away. Having all your scan data in one organized place makes it easy to track progress across multiple appointments. Visualize Growth Over Time Once you have logged two or more fundal height entries, baby size tracker draws a personalized growth chart showing your measurements plotted alongside the clinical reference curve. Watching that line climb is one of the most reassuring parts of tracking weekly baby size, and the chart updates automatically every time you add a new entry. Full Pregnancy Timeline Browse the complete week-by-week timeline to see how the size of baby evolves across all three trimesters. Each week shows the fruit comparison, length, weight, and a development highlight. Tap any week for a deeper look at what is happening and a gentle wellness tip just for you. Past weeks are marked so you can see how far you have come. Track Your Personal Milestones Baby size tracker includes a personal milestone board where you can record every meaningful moment — your first kick, your anatomy scan, the first time you heard the heartbeat, or any memory you want to hold onto. Every milestone shows the week it happened, and confetti plays each time you save a new one.
