My son was born and I couldn't find a baby tracker that didn't want
our family's health data in some startup's cloud. So I spent my
evenings building one.
A year ago I had cervical spine surgery (ACDF). Recovery gave me a
new perspective — I started building things that actually matter to
me. HydroSleep is the first result.
The NAS sync was the feature I built for myself — we have a Synology
at home and I didn't want yet another cloud subscription. Turns out
no other baby tracker does this.
The PDF pediatrician report was my wife's idea. Now it's the feature
parents use most.
Built evenings after our son went to sleep. Happy to answer any
questions about the app or the stack.
