SleepCheck

SleepCheck determines whether you've slept today based on one simple rule: Heart rate below 55 bpm → sleep detected This threshold has been deliberately kept extremely simple. During sleep, your heart rate almost always drops below your normal resting level, making a fixed threshold of 55 bpm a reliable indicator for detecting periods of sleep. The widget uses this single rule to determine a clear and minimalist sleep status. Translated with DeepL.com (free version)
