Ratings & Reviews
New: Sleep Shield (iOS 26.5 or later). Pick apps that take a break before your bedtime, while your night is recording, or in the morning. You set the times and can switch it off at any time.
With Premium you can record up to 5 alarm tones of your own, for example with your voice.
Your nights are saved more reliably. If data is missing, the graph now shows a gap instead of a straight line.
