Generic advice fails the people who need it most. If your body clock runs late, “go to bed earlier” isn't a tip — it's a recipe for lying awake. Vitra now lets you tell it how you actually work, and quietly changes what it suggests.
Sleep and recovery advice is usually written for an imaginary average person: sleeps at eleven, drinks the odd glass of wine, has a coffee at nine. If that's not you, the standard tips don't just miss — they can actively mislead. Telling someone with a delayed body clock to force an earlier bedtime is telling them to spend an hour failing to sleep.
Vitra's premise is the opposite of one-size-fits-all: the read should be tuned to you, not a population average. Part of that is your own baselines — but part of it is knowing a few things about you that no ring can measure.
During setup — and any time later, in Settings — Vitra asks whether a few things fit you. A body clock that runs late (delayed sleep phase). Sleep shaped by trauma. That you don't drink alcohol. That you don't use caffeine. Each one is optional, each one is a single tap, and each one changes the advice you get.
Turn on the delayed-clock setting and Vitra stops telling you to go to bed earlier. Instead it surfaces the guidance that actually shifts a late clock: a fixed wake time, bright light right after waking, and — if you and a clinician choose it — carefully timed low-dose melatonin. It's the difference between advice that fights your physiology and advice that works with it.
If your sleep is shaped by trauma, Vitra softens its language and stops treating a 3 a.m. waking as a discipline failure — because it isn't one. It points toward approaches with real trial evidence, like imagery rehearsal for recurring nightmares or trauma-adapted CBT-I, rather than a list of sleep-hygiene rules you've heard a hundred times.
Tell Vitra you don't drink, and it will never pin a rough night on alcohol or suggest cutting back on something you already don't do. Same for caffeine. Small things — but being told to cut out a vice you don't have is exactly the kind of generic noise that makes people stop trusting an app.
These are sensitive facts, so they're treated that way. Everything you tell Vitra here lives only on your own device — it's never uploaded to a server, and never shared. Vitra's guidance is research rules and your own rolling baselines, computed on your Mac or PC. Nothing about your health, or your history, leaves your machine.
