I built a free baby tracker that syncs across devices without requiring an account

Hey everyone! I recently became a dad, and let me tell you - nobody warns you about the logistics nightmare that comes with a newborn.

The Problem

First few days home, we tried tracking everything on paper. Feeding times, which breast, how long, diaper changes, sleep... The notebook quickly became an unreadable mess. Then came the constant texts between me and my wife: "When did you last feed her?" "Which side?" "Did you change her?" "How long has she been sleeping?"

We tried existing baby tracker apps. One wanted us to create accounts and verify emails - not happening at 3 AM with a screaming baby. Another had half the features locked behind a $10/month subscription. A third one had sync, but required both of us to sign up separately and then somehow "connect" our accounts through a confusing process.

I just wanted something simple. Log stuff. Share with my wife. That's it.

The Solution (That Grew Into Something More)

So I built a quick app for myself. Just feedings at first - tap, log, done. Shared it with my wife through a simple sync key.

Then we needed sleep tracking. Added that. Then diapers. Then weight for doctor visits. Then a timer because we kept forgetting when the feeding started. Then dark mode because I blinded myself one too many times at night.

Two months later, that "quick app" became Zaspa - a full baby tracker that actually solves the problems we had.

What Makes It Different

No accounts, no passwords, no BS - You generate a random sync key, text it to your partner, they enter it, done. You're both tracking the same baby in real-time. No email verification, no "forgot password", no account management. Your data stays anonymous on our servers - we don't store baby names or any personal info.

Actually works at 3 AM - Big buttons, one-handed operation, minimal steps to log anything. When you're half-asleep holding a baby, you don't want to navigate through menus.

Fix mistakes easily - Forgot to log a feeding an hour ago? Just adjust the timestamp. Started the timer late? Edit the start time. Life with a newborn is messy, the app handles that.
