You’ve been timing contractions for three hours. They’re getting closer together. She’s uncomfortable. You’re both exhausted.
And you have no idea when to leave for the hospital.
Every contraction timer app tells you how long and how frequent. But none of them answer the questions that actually matter: When will the baby arrive? When should we leave? What should I be doing right now?
If you’ve felt that panic—the uncertainty of not knowing whether you’re leaving too early or dangerously late—you’re not alone. And that’s exactly why I built Baby ETA.
The Problem: Birth Partners Need Different Tools
Most contraction timers are designed for the person in labour. But here’s the thing: you’re not in labour. You’re the support person trying to make critical decisions while keeping your partner comfortable and calm.
You need to know: - When to call the hospital - When to grab the bags and go - What to say (and what not to say) during each phase - Whether this is “real labour” or false alarm
Generic contraction timers can’t help with any of that. They just track time and hope you know what to do with the data.
What Makes Baby ETA Different
Baby ETA is the only birth partner app that combines evidence-based arrival predictions with real-time coaching.
Instead of just showing you contraction timing, Baby ETA tells you: - When your baby will likely arrive (using ACOG 2024 guidelines and data from 75,000+ births) - When to leave for the hospital (accounting for your location, traffic, and even weather) - What to do at each moment (with contextual “Supporting Tips” like “Hold her hand, stay present, say little”)
It’s not just a timer. It’s your coach, your guide, and your reassurance during one of the most intense experiences of your life.
What’s New in Version 1.5
Today we’re launching Baby ETA v1.5 with 21 new features and improvements. Here are the highlights:
AI Coaching Mode
Baby ETA now proactively reminds you of things you might forget in the chaos: - “Remind her to drink water” - “Suggest a position change” - “You’ve been up for 6 hours—take a quick break”
The app watches labour patterns and gives you timely nudges based on what phase she’s in and how intense contractions are.
Completely Hands-Free
Your hands are busy during labour. We get it. That’s why v1.5 adds: - Siri Shortcuts: “Hey Siri, start contraction” - Lock Screen Live Activity: See status without unlocking your phone - Apple Watch complications: ETA on your watch face
You can track everything without fumbling with your phone when she needs your attention.
Smarter Predictions
We’ve enhanced the prediction engine with: - Contraction intensity tracking (1-10 scale after each contraction) - Confidence scoring showing whether predictions are Low, Medium, or High accuracy - Weather-aware timing that adds buffer time if there’s rain or snow - Historical comparison for second-time parents (compare to your first labour)
Enhanced Supporting Tips
We’ve expanded our database to 30+ contextual tips that rotate based on what’s happening: - Early labour: “Keep her distracted. Watch a movie, go for a walk.” - Active labour: “Hold her hand during contractions. Maintain eye contact. Breathe with her.” - Transition: “She might say ‘I can’t do this.’ Remind her: You’re almost there. You’re so strong.”
Built by a Birth Partner, For Birth Partners
I built the first version of Baby ETA during my partner’s labour.
We’d arrived at the hospital too early (four hours too early, to be specific), got sent home, and I spent the next eight hours in a state of anxious uncertainty. When should we go back? What if we miss the window? What am I supposed to be doing right now?
Every contraction timer I tried just showed me numbers. None of them told me what I actually needed to know.
So I started building Baby ETA between contractions. The first version was rough—just a timer with a basic ETA prediction. But it helped. It gave me confidence when I felt lost.
Version 1.5 is what I wish I’d had that day. It’s everything I needed but couldn’t find: predictions I could trust, coaching I could follow, and tools that actually fit how birth partners experience labour.
