Not Just Diagnostics. Real Training.
From day one, our goal has been to go beyond simply measuring grip strength. 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
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.
Tailored Workouts
Using your max strength as a baseline, Protocol generates workouts calibrated to your level. Every rep guided, every set tracked. As you improve, your workouts scale with you automatically.
Party Mode
Challenge your friends and family. Add multiple guests, compare scores, and compete head-to-head — making grip training social and genuinely fun for everyone in the room.
