Calm, honest software
for people's health.
Silver Fern Labs is an independent studio in Aotearoa New Zealand. We build health tools that tell the truth about what they know, stay quiet when they don't, and keep your data where it belongs — with you.
What we're building
A fasting and metabolic health app with real safety rails, glucose insight without the noise, and an AI coach that only ever carries what you've agreed to share. Currently in closed beta on Android.
How we work
Measured, modelled, or logged — every figure in our software declares where it came from. Estimates are labelled as estimates, always.
No streak pressure, no badges, no engagement machinery. Software should lower the noise in a person's day, not add to it.
Local first, no analytics, no ad trackers, nothing leaves a device without explicit, revocable consent. We build as if we'll never see your data — because we don't.
Made in New Zealand
Built with the patience of a long coastline walk — designed for everyone, everywhere.
