About 40Weeks - AI Ultrasound Viewer
━━━━━━━━━━━━━━━━━━━━━━━━━━
📖 40 weeks, your first record with your baby
━━━━━━━━━━━━━━━━━━━━━━━━━━
With a single ultrasound photo,
meet your baby a little more vividly.
40Weeks is a pregnancy journal app that uses AI
to visualize your baby week by week, based on your ultrasound image.
It is more than an image —
it helps you picture the baby you have been imagining
in a little more detail.
※ Images provided by this service do not show your actual baby.
They are predictive simulation images generated by AI based on medical data.
━━━━━━━━━━━━━━━━━━━━━━━━━━
🌱 Why 40Weeks?
━━━━━━━━━━━━━━━━━━━━━━━━━━
Pregnancy lasts only 40 weeks.
But an ultrasound photo alone
doesn't make it easy to imagine what your baby looks like.
40Weeks reconstructs your baby's appearance with AI,
starting from your ultrasound image and reflecting
gestational week and developmental data.
"What does our baby look like right now?"
40Weeks offers one way to experience that question.
━━━━━━━━━━━━━━━━━━━━━━━━━━
🔬 AI visualization
━━━━━━━━━━━━━━━━━━━━━━━━━━
· AI feature analysis of the ultrasound image (automatically reads gestational week, fetal size indicators, and more)
· Reflects developmental data for each week of pregnancy
· Generates images based on the baby's outline, proportions, and position
· Retake guidance when the photo doesn't meet the conditions
※ Result images are AI-generated predictions, not real images.
※ This app does not estimate or show the baby's sex.
