HLS Labs
We're a small product lab that builds tools to watch the chaos so you don't have to — starting with the five calendars your family actually lives by.
Our projects
One at a time, finished properly.
Every schedule your family lives by, watched for you.
School, sports, and work calendars sync themselves. A deterministic change engine catches every moved practice and cancelled lesson — and the right parent hears about it the moment it happens.
How we build
Dates, times, and places are deterministic data — parsed, diffed, and traceable to their source. AI can write prose around facts. It never gets to invent them.
No streaks, no badges, no engagement bait. Good software reduces the number of things you have to check. It doesn't add one more.
Provenance on every event. A receipt for every notification. Privacy-minimal profiles for kids. Your data exports whenever you want it to.
About
HLS Labs was founded in 2026 — an engineer, an operator, and a builder who were tired of learning about schedule changes after they mattered. We're bootstrapped, deliberate, and building for the long haul.
