Stop guessing. Run a real experiment on your sleep.
Coming soon to the App StoreMost sleep apps track your sleep and hand you generic advice. Sleep Scientist treats better sleep as an experiment: pick one thing to change, hold it on a schedule, and find out whether it actually improves your sleep — measured automatically from the data your devices already collect. No nightly logging, no accounts for personal use.
Choose an intervention — no caffeine after noon, phone out of the bedroom, an earlier wind-down. Your own past sleep is the control. Everything stays on your device; nothing is uploaded.
Take part in randomized trials run by researchers, anonymously, to build real shared knowledge about what works — not just for one person. Many studies are blinded to keep the results unbiased.
Sleep is read from Apple Health (Apple Watch / your sleep app). You don't log anything.
It tells you when there isn't enough data, or when a change is just noise — and never claims proof from a handful of nights.
The best intervention is the one you keep doing. Studies follow up over time on whether it sticks — and why.
No ads, no trackers. Personal experiments never leave your device; community participation is anonymous.
Sleep Scientist hosts studies — you run them. Publish a randomized trial, set your own consent form, restrict which regions you accept participants from, choose blinding and duration, and attest your ethics approval. How to run a study →
