Live Mendelian math — probabilities, not promises

How It Works

  1. Input Genetic Data

    Enter eye color, hair color, skin tone, and other traits for both parents. For maximum accuracy, add grandparent traits to account for recessive genes.

  2. Genetic Calculation

    Our Mendelian genetics engine calculates probabilities using Punnett squares, polygenic inheritance models, and multi-gene interactions.

  3. AI Visualization

    The AI generates realistic baby images guided by genetic probabilities - not random blending, but science-informed visualization.

What Parents Are Saying

Illustrative examples of parent feedback from around the globe

The genetics predictions were spot-on! Our baby has my blue eyes and my husband's dark hair, exactly as predicted with 92% confidence.
Sarah M.First-Time Mom · USA
Finally, an app with vaccination schedules for my country! I'm in South Korea and no other app had our specific schedule. ProbaBaby has it all.

The hospital bag checklist knew exactly what I needed for our 2-day stay in California. No overpacking, no forgetting essentials. Perfect!
Jessica R.California, USA
Best baby tracking app. Simple mode is a lifesaver at 3 AM when you're exhausted. Just tap a button and it logs everything.
David P.New Dad · Canada
As a geneticist, I'm impressed by the accuracy of the Punnett square calculations. This app actually understands Mendelian inheritance!

241 countries! I live in a small Caribbean island and every other app forgot about us. ProbaBaby has our emergency numbers, hospital data, everything.

The contraction timer with Live Activities is genius. I could track contractions from my Lock Screen without unlocking my phone during labor.
