Causal Lens

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.
