About this app

Lumo is an always-on night clock with a huge display. Leave this big clock on the bedside, dim the screen, and read the time from across the room. The night clock stays awake all night.

Use Lumo as a Shabbos clock. The screen stays on, the time stays large, and you can keep a short note on the clock for a door code or an address. It is a simple night clock for Shabbos, for Shabbat, and for any night you want a Jewish clock app that just shows the time.

This night clock is also a noise machine for sleep. Play white noise, pink noise, brown noise, blue noise, or grey noise, plus a soft fuzz. These sleeping sounds fade in and out, and the volume stays where you set it. White noise for sleep, in the same app as the big clock.

What you can do with this night clock • Keep a huge clock on the screen all night • Turn the phone sideways for an even bigger clock • Dim the brightness and choose a clock color that is easy on your eyes • Turn on the flashlight • Play white noise, pink noise, brown noise, and other sleep sounds • Save a note, such as a door code, on the night clock • Use 24-hour time • Open Do Not Disturb from the clock

Lumo is the always-on night clock for sleep, a Shabbos clock with a huge display, and a white noise machine for the bedroom.
Big always-on night clock, Shabbos clock, and white noise sleep sounds.
