Quantum Insights vs Longa

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 — 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 — your personal AI data coach — 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 — custom metrics for any habit, supplement, feeling, or behavior Cross-domain correlation engine — find connections across all your data automatically Q AI coach — ask your data questions in plain English and get real answers Frictionless logging — built to be fast enough that you'll actually stick with it N-of-1 experiments — design personal experiments and measure what actually works CSV import — bring in data from apps you already use Your data stays yours — 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

Your health data already exists. Longa explains it. Every morning, Longa reads your Apple Health data and writes you a few honest sentences about how yesterday actually went — measured against your own 7- and 30-day baselines, not population averages. Not another dashboard of scores to decode. YOUR MORNING READ How you slept, where your HRV and resting heart rate landed, whether you're recovered, and one thing worth doing today. In plain language, in about the time it takes to drink coffee. ASK ABOUT YOUR OWN NUMBERS "Why am I tired?" "Is my resting heart rate trending up since I changed jobs?" "Am I recovered enough to train?" Longa answers from your actual data, not generic advice — and shows the numbers it used. MEASURED AGAINST YOU Your baselines, not averages for your age bracket. A 52 ms HRV means nothing on its own; what matters is whether it's up or down for you. FOR LIFTERS Connect Hevy and Longa reads your full training history alongside sleep and recovery — spotting lifts that have been flat for months, and building updated routines back into Hevy once you confirm them. WEEKLY RECAP Every Sunday, the bigger picture: what moved, what didn't, and what to prioritise next. BUILT ON APPLE HEALTH Works with whatever you already wear. If your watch or ring writes to Apple Health, Longa can read it. PRIVATE BY DESIGN Your health data is read on your iPhone and processed only to answer you — never stored on our servers. Your chats and reports live on your device and your own iCloud. The morning report is free. Longa Pro unlocks the full report and unlimited coaching, with a free first week. Longa Pro is an auto-renewable subscription. Cancel anytime in Settings.
