Gyroscope is not just an app, but a new operating system for the human body. You’ll be able to see everything about your biology, and update your internal systems for our modern world. Better nutrition, better exercise, better living with AI. With the world’s first Health Camera, now tracking your life is as simple as taking a photo. Use the app to take a photo of everything you eat (and drink) to get realtime and accurate data. While there are many other photo food camera apps on the market now, Gyroscope is the most accurate and combines photos, text labels, scale data, nutrition labels and years of data for the most reliable tracking system. With Gyroscope One, you can track everything in one place: your food, fasting, mood, meditation, exercise, travel, sleep, glucose, productivity, and thousands of devices like Apple Watch, wifi scales, glucose monitors, blood pressure cuffs, and more. Even if you don’t have any devices, the app can measure essentials like mood, calories, protein, travels, sleep, food and more! Successfully losing bodyfat and staying healthy long term takes more than just eating less. In the app, you can get the full checklist of best practices to make sure you follow the right protocol to not only lose weight, but also keep your muscle mass.

Stop Guessing. Start Discovering. Most health apps tell you what happened, but they rarely tell you why. Causal Lens goes beyond simple charts, using advanced statistical analysis, Causal Inference, to find invisible threads connecting your daily habits to your overall well-being. Do those extra steps today actually decrease your resting heart rate tomorrow? Key Features: The Discovery Engine: Identify which habits actually move the needle. See your "Average Treatment Effect," the real world number representing how one metric influences the other. Connected States: Discover your biological feedback loops. Understand circular relationships, like how better sleep gives you the energy to move, which in turn helps you sleep. Interactive Trends: High Fidelity, smooth charts that allow you to zoom into the details or scroll through years of historical data. Total Privacy: Your health data is yours alone. Our engine runs 100% locally on your iPhone's silicon. No cloud uploads, no external servers, no tracking. Ever. Smart Filtering: Our sparsity filer ensures you only see patterns built on consistent, statistically significant data. No noise, just insights. Finally, we believe that your time and data are personal and valuable. We don't collect any health data and have no servers to store it. This app runs completely on your phone. Also, we don't think apps should be begging for your attention; life is better outside your phone. That is why we have developed this to be fast and easy to read and use, without sending notifications to try and get your attention. Medical Disclaimer: This app provides statistical analysis of historical Apple Health data for informational and educational purposes. Causal Lens is not a medical device. The insights provided are not intended to diagnose, treat, cure, or prevent any disease. Always consult with a qualified healthcare provider before making changes to your health, diet, or exercise routines.
