Gritvit: Fitness Community

Fitness apps lie. Anyone can claim they train, and there's no way to verify. Gritvit changes everything.

Gritvit is the first fitness community where every athlete proves they train with real, verified health data. Not claims. Not photos. Science.

HOW IT WORKS
Step 1: Create your profile and connect Apple Health or Health Connect.
Step 2: Complete the 7 day fitness challenge to prove you actually train. Hit 50,000 steps, 40 km distance, and 200 active minutes to unlock the community early.
Step 3: Gritvit analyzes 8 health signals to build your Fitness Score (0 to 100). Resting heart rate, workout frequency, cardio volume, daily steps, active calories, and more.
Step 4: Our ranking algorithm sorts athletes in your feed based on sports compatibility (40%), fitness level proximity (35%), location (15%), and demographics (10%). Science, not luck.

WHY GRITVIT?
Every profile is verified. Every connection is earned. Gritvit is not for everyone, and that is the point. This is a space for people who put in the work and want to train alongside athletes who do the same.
Your Fitness Score updates with your training. Stop working out, and your score decays. Stay consistent, and you climb the leaderboard. Your workouts literally decide where you stand.
