Your body has a signal. Learn to read it.

Training, recovery, sleep and daily demands all shape your stress response. Cortisol is the hormone at the centre of it. BIOTRACKR.PRO lets you measure it at home, from saliva, and see how your levels move through the day.

• At home. A saliva sample, no needle, no lab.
• Rapid. A result in about 10 minutes per test.
• Your rhythm. Three tests, three time points: morning, midday, evening.
• Digital insights. Scan each test with the BIOTRACKR.PRO app to read and track results.
• Actionable awareness. Read your results alongside sleep, training load and recovery.

How it works

01 Collect. Take a saliva sample at home. 02 Measure. Run the rapid test, about 10 minutes. 03 Understand. Scan with the app and build your pattern over time.

Measure. Monitor. Manage.

BIOTRACKR.PRO is a wellness monitoring tool, not a diagnostic test. Cortisol is one biological signal among many. Speak with a healthcare professional about your individual readings, especially if you take medication such as corticosteroids.
