About

Quantum Insights

Most tracking apps show you what happened. Quantum Insights shows you why. You track sleep. You track workouts. You log supplements, mood, energy. But none of those apps talk to each other โ€” and none of them answer the question that actually matters: what's affecting what? Quantum Insights pulls everything into one place. Define your own metrics, import data from apps you already use, and let Q โ€” your personal AI data coach โ€” find the patterns across all of it. Does sleep predict your mood? Does meditation move the needle on anxiety? Does caffeine timing affect your focus? Stop guessing. Run the experiment. Get the answer. What makes Quantum Insights different: Track anything โ€” custom metrics for any habit, supplement, feeling, or behavior Cross-domain correlation engine โ€” find connections across all your data automatically Q AI coach โ€” ask your data questions in plain English and get real answers Frictionless logging โ€” built to be fast enough that you'll actually stick with it N-of-1 experiments โ€” design personal experiments and measure what actually works CSV import โ€” bring in data from apps you already use Your data stays yours โ€” export everything, delete anytime Terms of Use: https://tanstack-start-app.quantuminsights.workers.dev/terms Privacy Policy: https://tanstack-start-app.quantuminsights.workers.dev/privacy
