A baby tracker
that doesn't suck.
No subscriptions. No ads. No dark patterns. Two parents, one newborn, and an app that gets out of the way.
Testers get everything free — including SmartNap. All I ask is that you tell me what's broken.
Why this exists.
My wife and I are about to be first-time parents. August 2026. We're naming her Clementine.
We're both product people. So obviously the first thing we did after the joy and terror subsided was start downloading baby trackers. We need to track feeds, sleep, diapers. We need to both see the same data at 3 AM when neither of us can form a sentence. Pretty standard stuff.
Every app we tried was awful.
$10/month to track when your kid pooped. Seriously.
And look, I get it. I've been in product for 16 years. I understand the playbook. Captive audience, short monetization window, parents who are desperate and sleep-deprived and will pay for anything. It's a textbook extraction setup.
But knowing why the market looks like this doesn't make it less gross. New parents don't need one more thing trying to extract money from them. They need a fucking break.
So I built it.
Clementine tracks feeds, sleep, diapers, pumping, growth, meds, and more. No ads. No subscriptions. No analytics. No third-party SDKs. Your baby's data lives on your phone and your private iCloud. We never see it.
Core tracking is free. SmartNap, the sleep prediction system I accidentally built after losing several weekends to infant sleep research, will be a one-time $4.99 purchase with Family Sharing at launch. You buy it once, both parents get it. That's the whole business model. No recurring charges, no unlocking basic features behind a paywall. If I'm going to charge for something, it should be something that actually took real work.
Right now, though? Testers get everything — SmartNap included — completely free. The only thing I'm asking for is feedback.
The basics.
Everything you actually need. Nothing you don't.
Feeding
Breast (per-side timer, pause, switch), bottle (amount + type). One tap. Both parents see it.
Sleep
Start/stop timer, daily totals. Live Activity on your lock screen so you don't even have to unlock the phone.
Diapers
One tap. Wet, dirty, both. Done. Logging a diaper shouldn't be harder than changing one.
Growth
Weight, length, head. WHO percentile charts. Export a PDF for your pediatrician.
Medicine
Vitamin D, meds, whatever. Dose tracking with reminders because 3 AM you will not remember.
Everywhere
Home screen widgets, lock screen, Dynamic Island, Apple Watch. Log from your wrist while holding a sleeping baby.
What we won't do.
Every baby tracker we downloaded did at least three of these.
$9.99/month subscription
$4.99 once, Family Sharing included
Ads between diaper logs
Zero ads, zero tracking
Social features nobody asked for
Two parents, one baby, that's it
Sync that doesn't actually sync
iCloud sync that just works
Built for two.
This was the thing that kept breaking us with other apps. Either sync flat-out didn't work, or it was a premium feature, or both parents needed separate accounts with separate subscriptions. Wild.
Clementine uses CloudKit under the hood. One parent creates the baby profile, sends an iCloud invite, done. Both of you see the same data in real time. No accounts. No logins. No servers I maintain. It's Apple's infrastructure doing the work.
When you log a feed at 2 AM, your partner sees it immediately. Widget updates. Watch updates. Nobody has to whisper "did you already feed her?" in the dark.
SmartNap: the rabbit hole. 🕳️
This is where I lost a few weekends. I started reading about infant sleep science and just... kept going. Wake windows. Circadian development in newborns. How breast milk and formula affect sleep onset differently. How sleep pressure accumulates in the first year.
Turns out there's a lot of real clinical research on this. The American Academy of Sleep Medicine publishes baselines for every age group. Wake windows go from 45 minutes at two weeks old to 5+ hours by age two. And the things that modify those windows are well-documented.
So I built a prediction engine. Entirely on-device. No cloud ML, no data leaving your phone. It degrades gracefully depending on how much data it has:
🧪 Clinical (day 1)
Published age-based baselines. No logging needed.
📊 Rolling (3+ days)
Starts learning from your baby's actual patterns. 5 modifiers.
🧠 Full (7+ days)
11 modifiers, exponential moving average, personalized predictions. Adapts daily.
It tracks circadian phase, feeding type, activity, nap length, 3-day sleep debt, regressions, eating regularity. Each modifier has a bounded range grounded in published research. Circadian alone shifts the window by -8 to +12 minutes depending on time of day.
Honestly? TBD if it works on a real baby. But the science is sound, the math checks out, and the confidence scoring tells you when it doesn't have enough data. I'd rather be honest than pretend to be certain.

Free for testers. All of it. Just tell me what sucks.
How it got built.
I'm a product person, not an iOS engineer. Never shipped a native app before this. The whole thing was built with a lot of AI help, a lot of Apple documentation read at unreasonable hours, and the kind of stubborn energy that comes from being told "just use Huckleberry, it's fine."
Zero external dependencies. SwiftUI, Core Data, CloudKit, WidgetKit, WatchKit, Live Activities, App Intents, Swift Charts, StoreKit 2. The whole Apple stack, nothing else.
The mascot is drawn entirely in code. No image files. Six different expressions, all SwiftUI geometry. I genuinely don't know why I did it that way. It felt right at the time.
43 TestFlight builds so far. Build 30 was when Live Activities finally rendered after four straight builds of debugging a blank lock screen. Build 39 was the nursing logic rebuild where side-switching finally made sense. Build 42 was the SmartNap overhaul that threw out the original prediction engine and rebuilt it from real clinical baselines.
Hardest and most fun thing I've built in 16 years of doing this.
Want to try it?
Clementine is in TestFlight. If you're expecting or have a newborn, I'd love for you to test it and tell me what's broken.
Testers get the full app — every feature, including SmartNap — completely free. No catch. The only thing I'm asking for is honest feedback. What works, what doesn't, what made you want to throw your phone. All of it helps.
