A focused sleep-experiment companion.

One intervention at a time. Honest answers about whether it's actually working.

What it is

NightCue is an iPhone app for people who want to test, one at a time, the things that might be affecting their sleep — caffeine cutoff times, magnesium, room temperature, fixed bedtimes, and similar low-risk lifestyle and supplement interventions.

You connect your Oura ring, log a short daily check-in about what you actually did the previous evening, and NightCue uses that data to give a single, structured read on your current experiment: keep going, it's too early to tell, or stop and switch. No medical claims, no coaching, no AI chat — just a disciplined way to learn what genuinely helps your sleep.

Status

NightCue is in closed private beta. The app is not available on the App Store, has no public sign-up, and is not intended for general use at this stage. Access is by invitation only.
