— The SleepUntil ideaAbout SleepUntil
A new starting point for the alarm clock.
SleepUntil was created around a simple observation: bedtime is often flexible, but the amount of sleep you want can be easier to decide. Instead of starting with a fixed wake time, SleepUntil lets you start with your desired sleep duration.
The product is being developed as an Android-first experience, with a roadmap that includes deeper wearable and health-platform integration.
