Latest release

What’s New

Version 3.3 Aug 11, 2026

Your alarm now rings on time, with the sound you chose. [New] - Set your own sleep length, anywhere from 4 to 12 hours in 15-minute steps. - Start from bedtime instead of wake time and get a suggested time to get up. - Add a Bedtime Countdown widget to your Lock Screen. Pick one of three designs, and tap it at bedtime to start sleep mode right away. [Improved] - The whole app got a visual tidy-up: consistent type, spacing, and fewer colors. - On nights you start sleep mode, your wake alarm sounds just after your wake time even if the app closes overnight. - Home shows last night's sleep as soon as you wake up. - Snoring measurement keeps going if a call comes in, and the measured time is more accurate. - Nights when the microphone was off now show snoring as "Not measured" instead of 0 minutes. [Fixed] - Saying no to notifications no longer leaves you stuck on the welcome screens. - Your wake alarm and bedtime reminder now ring with the sound you picked. - The alarm rings even if your screen was off when your wake time arrived. - Your sleep history no longer disappears, and nights you slept by tapping the star show up on Home and in your stats. - Turning off bedtime reminders no longer turns off your wake alarm. - Snooze on a bedtime reminder now brings it back at the time you picked. - If you take a call while the alarm is ringing, the alarm starts again once the call ends. - Nights you slept with the microphone turned off are now saved to your sleep history. - On devices that use AM/PM, bedtime no longer shows as a 24-hour number. - Your streak stays intact when you open the app after midnight. - Changing your wake time now clears an alarm left at the old time.
