Hypnogram

About

Your sleep tracker tells you how you slept. It never tells you why. Hypnogram is the missing layer. You log what you actually did — alcohol, exercise, room temperature, morning sunlight, a wind-down routine — and it compares the nights you did each thing against the nights you didn't. Your nights, against your other nights. Never against an average, never against a guideline. HOW IT WORKS Connect Apple Health and Hypnogram reads whatever already writes sleep to your phone: an Apple Watch, an Oura ring, Whoop, Sleep Cycle, or any other sleep app. If you have history there, it can use up to two years of it on the first night. No wearable? The phone's own microphone can estimate your sleep instead — less accurate, and it says so. Then log your habits in under a minute a day. Every habit you track becomes a ranked card showing the average on the nights you did it, the average on all your other nights, and the difference between them. WHAT IT WILL NOT DO It will not tell you that a habit improves your sleep. It measures which habits line up with your better and worse nights — association, not cause. Your results might say the opposite of what you expected, or nothing at all, and the app will say so plainly. It needs at least three nights with a habit and three nights without it before it will rank anything. Something you do every single night has nothing to compare against, so it never gets a card. The things you sometimes skip are the ones that can actually be measured. It is not a medical device and does not diagnose anything. YOUR DATA STAYS ON YOUR PHONE No account. No sign-up. No cloud sync. No analytics, no trackers, no advertising SDKs. Your sleep and habit data never leaves your device, because there is nowhere for it to go — Hypnogram has no server. FREE Full sleep tracking, and four habits to test: alcohol, exercise, room temperature, morning sunlight. Patterns across your last 90 days. PREMIUM Every built-in habit — caffeine cutoff, screens before bed, supplements, mouth tape, naps, late meals, and more. Custom habits you invent yourself.
