What’s new
Version 3.4 · Updated September 8, 2026
You can now type the time straight in. [New] - Tap the numbers on the wake time or bedtime and a keypad comes up. Someone whose sleep time changes every day told me the scroll wheel was a chore, so I added this. - Dragging the number and the arrows still work exactly as before. Use whichever you like. - Filling both digits jumps to the next box, so 7:30 is just 730 and 11:45 is 1145. - On a device set to a 24-hour clock you can enter 0 through 23 directly, with no AM or PM to pick. - Late-night times written past 24, like 25:00, are read as the next morning.
