SleepUntil, the alarm that starts with sleep

sleepuntil.app Observed source
Editorial interest 78/100 Selection signal · not a rating of the site

An Android-first alarm app that lets you choose how long you want to sleep, then calculates when to wake you.

Landing page captured for the 2026-09-16 issue.

Field notes

SleepUntil uses a sleep-duration input rather than a fixed wake-time input: the page’s example lets someone choose between one and twelve hours, then displays the resulting wake time. Its stated four-step flow ends with the phone managing the active session while the user sleeps. Android is identified as the first platform, while Wear OS, Pixel Watch, and deeper health-platform connections are described as planned; the Google Play link still includes placeholder listing language.
