NightCue

NightCue helps Oura Ring users on iPhone run simple experiments with a single change to see what affects their sleep. Log a 60-second morning check-in, and after a couple of weeks, it analyzes your Oura data and gives a clear keep, wait, or drop verdict based on your own data and research rather than a good night or a gut feeling. It focuses on everyday tweaks like caffeine timing, room temperature, consistent bedtimes, and supplements and sticks to one job: telling you if your change actually worked, based on your own data, not generic tips.
