The iOS app
A lab notebook,
a coach, and a plan.
TestoTrack for iOS is built around three things: logging your labs in seconds, seeing your trend at a glance, and asking a coach that actually knows your numbers.

Core capabilities
Everything the trend needs. Nothing it doesn't.
LOGGING
Lab results in seconds
Enter total T, free T, and test date from any lab. Structured, validated, and stored in your personal record.
TRENDS
Longitudinal charts
Interactive trend views over 90 days, a year, or all time — with reference ranges so you know where you stand.
AI COACH
Answers with receipts
A RAG pipeline retrieves relevant, peer-reviewed research and combines it with your data before answering. No hallucinated health advice.
HISTORY
Full conversation memory
Your coach remembers previous conversations and your context, so guidance builds instead of restarting.
PRIVACY
Encrypted end to end
Health data is encrypted in transit and at rest. Your data is never sold, shared, or used for ads. Delete it anytime.
EXPORT
Doctor-ready output
Bring a clean summary of your history and trend to your physician — a better conversation in half the time.
Under the hood
Built like a serious product.
TestoTrack runs on a modern, production-grade stack — the same architecture patterns used by leading digital-health companies.
