The honest origin story isn't "I saw a gap in the market." It's that my twins were born a few weeks early, premature babies need closer feeding tracking than full-term ones, and after a week of trying every baby tracker on the App Store, my partner and I went back to a paper notebook.
The notebook was terrible. I lost it. The handwriting at 4am was unreadable. One of the babies peed on it. But the cognitive load of using it was still lower than any of the apps we'd tried — apps that wanted us to finish a 7-step onboarding before logging a single feed, or open three nested dropdowns to record a wet diaper.
So I built PooPeeMilk. One rule: logging an event takes one tap and zero thought. iOS now, Android next. This post is the technical write-up — what's in the stack, why each piece is there, and what I'd change.
What it actually does
Logs the four things new parents care about — feeds (breast or formula, with volume), diapers (wet or dirty), weights, and milestones with photos. From those logs it generates a 24-hour "rhythm ribbon" pattern view and a pediatrician-ready PDF for appointments.
