ClocksOn turns any spare iPhone or iPad into a calm, glanceable bedside clock. Full-screen, chrome-free clock face that automatically sizes itself to fill your display — readable from across the room, day or night. ADAPTIVE BRIGHTNESS The screen reads the light in your room and eases itself down as the room darkens, so it's never blinding at 2am and never washed out at noon. Prefer full control? Switch to manual brightness any time. LIGHT, DARK, OR SYSTEM THEME Pick a theme or let ClocksOn follow your device's setting. Your choice is remembered across launches. ORIENTATION LOCK Lock the clock to portrait or landscape, or let it follow the device automatically — useful when mounting an iPhone or iPad on a nightstand or wall dock. NO CLUTTER No accounts, no ads, no notifications competing for attention. Just the time, presented cleanly. Works beautifully on iPhone and iPad — set a spare device on your nightstand, dock, or desk and leave the clock on overnight.
