vs individual methods alone
Nub Theory Alone
Requires perfect scan angle. Often inconclusive.
Skull Theory Alone
Subjective and hard to read without training.
Heart Rate Alone
Old wives' tale. No better than a coin flip.
Best results with a clear 12–16 week profile scan. Our AI works best when your baby is in a good position. This is for fun and early insight — always confirm with your doctor! 💕

Frequently Asked Questions
How does it work?+
Upload a clear ultrasound photo from your 12–16 week scan. Our AI analyses the image using nub theory (genital tubercle angle), skull theory (forehead shape), and heart rate if visible. You get a boy or girl prediction with a confidence percentage in seconds.
What week should I be for best results?+
Between 12 and 16 weeks is the sweet spot. The nub is most visible during this window. Earlier than 12 weeks and the nub hasn't developed enough; later than 16 weeks and other methods become more reliable.
How accurate is it really?+
Our AI achieves around 91% accuracy by combining nub theory, skull theory, and heart rate analysis together — much better than any single method alone. Best results come from clear 12–16 week profile scans. It's a great early insight, though we always recommend confirming with your doctor at your 20-week scan!
Is my ultrasound photo stored?+
No. Your image is analysed in real-time and immediately discarded. We never store, share, or use your ultrasound photos for any other purpose. Your privacy matters.
Can I get a refund?+
Due to the instant digital nature of our service, we don't offer refunds. If you experience a technical issue, please contact [email protected] with your order reference and we'll help resolve it.
What if the prediction is wrong?+
No prediction method is 100% — not even traditional ultrasound at 12 weeks. Our AI combines multiple methods for the best possible early prediction, but this is designed for fun and early insight. We always recommend confirming with your doctor at your 20-week anatomy scan. Think of it as an exciting early peek, not a guarantee!
