FIXIT is an AI-powered health and fitness tracking app. Log workouts, nutrition, water, and body metrics, analyze your exercise form with AI pose detection, and visualize your progress over time — all in one place.

How does AI form analysis work?

FIXIT uses AI pose detection (TensorFlow MoveNet) to track 17 body keypoints from your camera. It analyzes joint angles, posture, and movement to score your form and flag issues like knee cave or forward lean — instant feedback, no coach required.

What can I track in FIXIT?

Workouts and exercises, food and calories, water intake, body-composition metrics (weight, body fat, InBody results), pain, and progress charts — with 100+ guided exercises.

How much does FIXIT cost?

FIXIT is free to start with core tracking. Basic is $7/month (full exercise library, unlimited sessions, progress charts) and Pro is $15/month (AI form scoring, video recording, 3D visualizations, and programs).

Is my health data private?

Yes. Your health data is stored securely and never sold. You control your account and can export or delete your data at any time.
