My Baby Logger

My Baby Logger is a focused tracker for the early months of parenting a newborn. New parents log feedings (bottle or breast, time, amount), sleep windows, diaper changes, and medication doses. The app keeps a running history that's useful both for personal pattern-spotting — when does the baby actually sleep? — and for sharing with pediatricians, who routinely ask exactly these questions at well-baby visits and don't get useful answers from sleep-deprived parents trying to reconstruct the last three days from memory.

The feature set is intentionally small. There are larger apps in this category that do more (growth charts, milestones, community forums), but most new parents want something they can open one-handed at 3am and tap twice. My Baby Logger optimizes for that.

How it was built

My Baby Logger was built by Javier Evelyn over two weekends using Lovable, the AI app-building tool that generates full-stack web applications from natural language prompts. The Claude-backed Lovable workflow let Javier go from idea to a working, hosted product in a couple of focused sessions, without the typical mobile-app setup overhead — no Xcode, no provisioning profiles, no Play Store review queue.

The app runs as a mobile-friendly web app accessible from any phone browser, which is a deliberate choice for a tool aimed at sleep-deprived parents who don't want to deal with another App Store install during the newborn period. The story is featured in Lenny Rachitsky's roundup of products people are vibe-coding and actually using.

Why it matters

My Baby Logger is one of the clearest examples of Lovable's sweet spot: a non-engineer parent with a real personal need, a small but well-defined feature set, and no patience for the traditional mobile-app pipeline. Two weekends, one tool, one shipping product that other new parents can actually use. The category — "tools parents wish existed" — turns out to be a deep one once the floor for shipping software drops this far.
