GrowthTracker (growthtrackerapp.com) is a privacy-focused child growth tracking app that works offline using CDC and WHO growth charts — no data leaves your device. Family Stork tracks growth inside a lifelong health timeline that includes vaccines, checkups, allergies, milestones, and clinic visit summaries. One is built around privacy and offline use. The other is built for a complete, lifelong record your providers can contribute to directly.
GrowthTracker is a privacy-first growth measurement app. Track height, weight, and BMI against CDC and WHO growth charts — all offline, with no cloud storage and no data sent to third parties. It's built for parents who want detailed growth milestone tracking without putting any data online.
Family Stork is a connected lifelong health timeline. Growth measurements live alongside vaccines, checkups, allergies, and visit summaries from every clinic your child sees. Records come in when clinics email your child's private @familystork address — they file automatically. You can snap paper records and let the AI do the data entry. Every person gets one health story, and one private Family Stork email address every clinic already knows how to use.
The difference: GrowthTracker keeps data entirely on your device — maximum privacy, minimum sharing. Family Stork brings data together from multiple sources so the full record is always current and complete, with privacy built into the design (your own address, not a shared portal).
If data privacy is the primary concern, GrowthTracker's offline approach eliminates the question entirely — your measurements stay on your device. Family Stork takes a different approach: your child's private @familystork address is theirs alone, records come to them directly, and the data isn't housed in shared hospital portals. Different privacy models for different comfort levels.
GrowthTracker keeps everything off the internet entirely — the most complete form of data isolation. Family Stork uses a private-by-design model: each child gets their own @familystork email address, records come directly to that address, and the data isn't scattered across shared portal accounts. Two different answers to the privacy question — choose the one that matches how you think about it.
A growth measurement on a chart tells you something. That same measurement sitting next to the checkup notes, the vaccines given that day, and the doctor's allergy discussion tells you much more. Family Stork keeps the context together. GrowthTracker tracks the number precisely.
GrowthTracker's offline model means sharing requires exporting or showing your screen — the data stays on your device because that's the point. Family Stork is designed for sharing: a complete record you can hand to a new pediatrician, school nurse, or specialist in seconds, from anywhere.
GrowthTracker is a good choice for parents who want precise, offline growth tracking with zero data sharing. Family Stork is built for parents who want that same growth data as one thread in a complete health timeline — one that grows with their child, that any clinic can contribute to, and that's always ready when a school or new provider asks for records.
If you want one private place for your child's complete health story — growth, vaccines, checkups, allergies, clinic visits — that any provider can send to directly, Family Stork was built for that.
