A LITTLE SCIENCE. A REASON TO PAUSE.
Why bedtime
needs a boundary.
The pull of “one more.”
Apps use notifications to bring you back, while likes and fresh content offer rewards you can’t predict. Experiments show that notifications can distract even without opening the phone, and social-media engagement responds to rewards. At bedtime, a deliberate pause is one way to interrupt that checking loop.

Light tells your body it’s daytime.
Evening screen light—especially its blue wavelengths—can suppress melatonin, the hormone that signals biological night, and shift your body clock later. That can delay falling asleep, even when you planned an earlier night. Effects depend on brightness, duration and timing.

BEFORE YOU CALL IT A NIGHT
A few good
questions.
What happens when bedtime starts?
On Mac, a translucent full-screen overlay appears on every display. On iPhone, Screen Time shields your selected apps and categories. On Android, an overlay covers selected apps when you open them.
What if I really need more time?
Enter your passcode for the grace period you chose (five minutes by default). The boundary returns when grace expires. You can also turn SleepGuard off. It’s a reminder you choose, not a lock you can’t escape.
Does it work after midnight?
Yes. A window like 23:30 to 08:00 runs through midnight and ends the next morning. Each device uses its local time. Settings are local to each device; they don’t sync.
Do you see what I do on my phone?
SleepGuard has no analytics or cloud account. iPhone app selection is managed by Apple’s Screen Time system. Android uses Usage Access on your device to detect when a selected app is in front. Your passcode is stored as a hash.
Is the download ready for everyone?
The Mac download is a local preview build, signed for testing and not yet notarized by Apple. Public Mac and phone releases are coming after signing, device testing, and store review. The phone store links are placeholders until their listings are ready. SleepGuard is free.
Will SleepGuard fix my sleep?
SleepGuard helps you follow a screen-time boundary you set. It isn’t a sleep tracker or a medical treatment, and it makes no promises about sleep outcomes. It simply helps make stopping a little easier.
TOMORROW STARTS TONIGHT.
