Built during my partner's labour because I was terrified and had no idea when to leave for the hospital or what to do. Baby ETA combines evidence-based arrival predictions (ACOG guidelines + 75,000 births) with real-time AI coaching that tells you exactly what to do at each moment. Hands-free with Siri, Apple Watch, and Live Activity. 100% private—no cloud, no accounts. It's everything I wished I had that day. $1.99 one-time purchase, no subscription.
