Our Mission

Not Just Diagnostics. Real Training.

By bringing full training into the app — with workouts tailored to your individual strength and endurance — we can help anyone improve. Whether you're an athlete chasing performance or someone investing in long-term health, Protocol is built for you.

Max Strength Test

Max Strength Test

The physical device connects to your phone via Bluetooth and transmits live force data — every pound you squeeze, captured in real time. Squeeze as hard as you can and we'll establish your baseline.

Analyze Your Results

After each test, your score is placed in the context of your age group and gender — so you can see exactly where you stand. Are you stronger than 84% of women in your age group? You'll know it.
